The side seam can be sewn with a braid pocket, a wing pocket or a pocket that is integrated to the side seam. NOTE - Possible applications! The CLOSING SEAM MACHINE 1282-4 has been designed predominantly for the sewing of trousers components. Therefore, the operation of the machine is described in these instructions using trousers components as examples. However, the machine can also be used for processing other sewing pieces, e.g. sleeves, rear seams of jackets etc. The prerequisite for the correct function is always that the length of the sewing pieces does not exceed the clear distance between the sewing head and the start position of the guide clamp and that the width of the sewing pieces does not exceed the distance between guide rail and worktable front edge. Fig. 2 The front and rear trousers components are placed onto one another with flush seams. The sequence for lining up the trousers components depends on the seam to be effected: • For sewing the crotch seam, the rear component is below, the front component is up. For sewing the side seams of these trousers components, the rear component is up, the front component is below. • For sewing the right trousers components, the sequence is inversed. The two trousers components 2 are inserted, with the hip side oriented toward the sewing unit 4, into the guide clamp 1where they are secured with the needle. If equipped with the optional cloth transfer machine component, the trousers components ends are inserted at the cloth transfer station where they are transferred to the guide clamp and secured. Then, the two trousers components are aligned with the contour guide 3 and lined up at the stop of the sewing unit 4. Machine cycle: Insertion process and machine cycle are effected from left to right: • The trousers components are lined up to guide clamp 1, contour guide 2 and sewing unit 3. • Top and bottom transport element of the sewing unit and the puller transport the sewing pieces to the sewing unit to be tucked and from there to the stacker. • During the sewing process, the automatic contour guide controls the routing of the seam. Fig. 2 -4- Closing Seam Machine 1282-4 Working Instructions B.2 Beisler Automated Sewing Equipment Functions of the machine Fig. 3/4 Guide clamp, Fig. 3: The guide clamp 5 is used as a guide for the trousers ends during the transport along a preset contour. This guide mechanism ensures that the trousers components are always lined up at the contour guide stop and at the sewing unit stop to maintain a constant sewing width and an even routing of the seam along the contour. During the transport, a counterweight 9 suspended from deflection rollers tensions the return ribbon 4 of the guide clamp and the cloth material without stretching it. The trousers ends 7 are inserted into the cloth holder holder clamp. The clamp is closed manually, the needle 6 holds the trousers components in the guide clamp. Just before the contour guide is reached, the trousers components are released from the guide clamp while the air-driven return lever 8 is activated and returns the guide clamp to the insertion station. Fig. 3 Guide rail, Fig. 3: The flexible guide rail 1 determines the route that the guide clamp takes. The shape of the guide rail is identical with the contour of the components to be sewn. The shape is determined by changing the position of the guide rod 2 in the clamp 3. Cloth transfer, Fig. 4: If the machine is equipped with the optional automatic cloth transfer 2 component, the trousers ends are inserted into the cloth transfer and transferred from there to the equally automated guide clamp 1 where they are fixed. -5- Fig. 4 Beisler Automated Sewing Equipment B.2 Closing Seam Machine 1282-4 Working Instructions Functions of the machine Fig. 5 Contour guide, Fig. 5: The contour guide 5 is the guide for the lower cloth layer. It is movable in two directions (X/Y). While the two trousers components are transported to the sewing unit, the contour guide automatically controls the shape of the contour in accordance with the presetting. In addition, a reduction of the seam from wide to narrow step width can be integrated in the automatic contour control. The two trousers components a and b are blown to the stop pins 9 of the contour guide using compressed air. If required, the cloth clamp 8 lowers at the start of the sewing process and fixes the two trousers components additionally for a freely selectable distance along the hem to prevent the trousers components from leaving the contour when the cloth thickens (e.g. pocket fly). The deflection plate 6 prevents the pockets from being caught in the contour guide during the transport. The following settings are possible for the contour guide: • The air pressure for blowing the trousers components to the stop pins 9 of the contour guide can be set at the throttle 2. • The setting of the two handwheels 3 and 4 depends on the material thickness of the cloths to be processed. • Use the handwheel 3 to set the distance between the center tab and the baseplate of the contour guide. Fig. 5 -6- This setting ensures the easy gliding of the trousers components through the contour guide and prevents the cloth contour from overturning at the stop pins. • Use the handwheel 4 to set the distance of the cover plate that holds the deflection plate 6 to the center tab 7 . Cloth guide, Fig. 5: To allow a seam to be sewn in tailor quality, the system can be equipped optionally with an additional cloth guide 1 for the line-up of the front trousers component. This feature is available only in connection with the optional pneumatic rule guide. Closing Seam Machine 1282-4 Working Instructions B.2 Beisler Automated Sewing Equipment Functions of the machine B.2.3 Transport and sewing Fig. 6 Sewing head, Fig. 6: The machine can be equipped with either a narrow or a wide sewing unit 2. The seam width is determined by the width of the pressure foot of the sewing unit and by the setting of the rule stop 7. The standard version of the system comprises the manually set rule stop 4 to ensure a constant seam width throuhout the entire length of the sewing piece. The pneumatically controlled rule guide 8 allows a tapered seam width by controlling the contour guide advance in the direction of Y using the shaft 6 and the catch 7. The photocell 1 at the sewing head controls the sewing start. When the reflection of the light beam on the reflective area 3 is interrupted by the cloth material, the pressure foot lowers. Depending on the preset start mode, the sewing process now starts fully automatically or must be started manually. The curve which the contour guide travels for controlling the closing seam is calculated by the program control, unit using the input X/Y values (see Section D, Programming Instructions). NOTE - Reflective film The reflective area 3 of the photocell must not be damaged as otherwise a failure of the sewing unit will occur. -7- Fig. 6 Beisler Automated Sewing Equipment B.2 Closing Seam Machine 1282-4 Working Instructions Functions of the machine Fig. 7/8 Transport unit, Fig. 7: The transport unit 1 consists of the puller 4 and the roller unit 2. The roller unit picks up the trousers components 3 from the sewing head transport and transports them along the worktable edge to the stacker (Fig. 8). The puller adapts its rotating speed correspondingly to ensure that the cloth contour is guided at the rule stop. If the sewing piece moves away from the rule stop, the puller reduces its rotating speed so that the sewing piece is pulled towards the rule stop. When the sewing piece is moved too close to the rule stop, the rotating speed of the puller is increased. To improve the gliding of the trousers components, the puller area has six compressed-air nozzles 5 in the working plate. The compressed air blows against the trousers components from below to create an air cushion that reduces friction. Fig. 7 Stacker, Fig. 8: The stacker 1 stacks the tucked trousers components. Fig. 8 -8- Closing Seam Machine 1282-4 Working Instructions B.2 Beisler Automated Sewing Equipment Functions of the machine Fig. 9 B.2.4 Switches The closing seam machine is equipped with three different types of switches: • Emergency switch for stopping a sewing program, • supply switch for current, • control switches for controlling the machine operation. Emergency switch Program stop switch When the program stop switch 1 is pressed, all machine movements and the sewing process are stopped immediately. The switch engages when pressed. Rotating the switch in the clockwise direction will unlock the switch, and it moves back to its original position. The control program performs a reset. Supply switches Main switch The main switch 2 is used to turn the power supply of the machine on or off. For safety reasons, the machine must be turned off using the main switch when it is standing still for an extended period; in this case, all functional units are deactivated. The main switch also serves as an additional emergency off switch. Fig. 9 -9- Control switches Pedal for machine operation The pedal 3 has two functions: It controls the machine operation gradually and it can be used to change the rotating speed of the sewing motor or the sewing speed of the sewing unit in twelve stages. Kneeswitch for machine operation The kneeswitch 4 is used to start fully automatic machine operation. Reset switch The reset 5 is used to restart the insertion process. If the lower ends of the trousers components are not clamped correctly into the guide clamp, actuating the catch will open the guide clamp; when the reset switch is pressed, the insertion process restarts.

To allow for testing machine movements or interval operation, the individual stages of movement can be activated with the inputs/outputs of the machine control unit (see programming instructions, Section D.4.3., Service menu level 1). Usually, the setting up of the machine is controlled by parameter values of the sewing programs (special parameters) and the parameter values of the machine control unit (global parameters). The following mechanical changes may be required additionally to ensure correct seams with the set parameter values. Guide rail adjustment: Fig. 12: The flexible guide rail 4 determines the routing direction of the guide clamp. The shape of the guide rail is identical with the contour of the pieces that are to be sewn 5. The routing is determined by changing the position of the guide shaft 3. Setting the contour: 1. Place trousers component under guide rail and align hip side with the sewing unit, with the contour guide stop and with the end at the insertion station. 2. First, set the slightly flat contour at the insertion station. Loosen fixing screws 2 of corresponding clamp elements 1, shift guide shafts 3 with guide rail to trousers hem and fix it there by tightening fixing screw 2. 3. Set guide rail finishing curve above the contour guide. Release clamping element locking lever 6, align guide rail curve with trousers component and fix it by tightening locking lever. 4. Position pick-up clamp 7. This clamp is used to disengage the trousers components from the guide clamp just before it reaches the contour guide. The traveling motion of the guide clamp should occur as late as possible; however, the pick-up clamp should stop the motion in a sufficient distance from the contour guide. Loosen knurled screw 8, position pick-up clamp at guide rail and secure it in this position by tightening knurled screw. 5. Tuck trousers components, check routing of seam and readjust guide rail if required. - 16 - Closing Seam Machine 1282-4 Working Instructions C.5 Beisler Automated Sewing Equipment Maintenance Fig. 13 Setting the contour guide: The following can be set at the contour guide: • material thickness of the cloths, • the pressure of the compressed air used to blow the trousers components to the contour guide stop, • lowering position and pressure to be exerted onto the upper trousers component, The setting is to ensure that: • the sewing pieces can be blown easily to the contour guide, • the trousers components glide easily on the worktable and maintain their position to each other during transport. Setting material thickness for sewing pieces: The setting for the material thickness is determined in a test by presetting the corresponding knurled screw and by a visual check at the contour guide stop. Fig. 13: The material thickness is set correctly if: • a single layer of the cloth can be blown easily to the contour guide stop 4, • a double layer of the cloth does not fit in the space between the baseplate 8 and the center tab 7 or between center tab and cover plate 8. 1. Set presetting for the lower cloth layer at knurled screw 2. 2. Set presetting for the upper cloth layer at knurled screw 3. 3. Avtivate blowing system using Input/Output function (see Section D, Programming Instructions). OUT 18: Activate blowing system, OUT 3: Close contour guide. 4. Check to see how the cloth glides to the stop 4 and readjust the knurled screws 2 and 3 repeatedly, as required. 5. Adjust the pressure of the blowing system. Rotate the throttles of valves 1 and 4 using a screwdriver. • front throttle 1 for upper cloth layer, • rear throttle 4 for lower cloth layer. To increase the blowing pressure, rotate the throttle clockwise; to reduce the pressure, rotate the throttle counterclockwise. - 17 - Fig. 13 Beisler Automated Sewing Equipment C.5 Closing Seam Machine 1282-4 Working Instructions Maintenance Fig. 14 Fig. 14: Setting the contour guide position 1: The start and stop positions of the contour guide in the direction of X and Y are set using the special parameters 36 and 39 (direct access via access level 2) of the program control (see Section D, Programming Instructions). The start and stop positions are aligned with the contour of the trousers components and should be set so that the cloth clamp is always lowered exactly onto the hem. The program control calculates the traveling motions of the contour guide as a curve. NOTE - Cloth clamp position! If the sewing of pockets is integrated in the side seam, the start position of the contour guide should be set in a way that ensures that the lower start point of the pocket is positioned before the contour guide and that the cloth clamp also checks the contour of the trousers until the start point of the pocket has been sewn. Fig. 14: Setting the pressure of the automatic cloth clamp: The clamping pressure of the cloth clamp at the contour guide can be set steplessly using the rotary button 2. - 18 - Fig. 14 Closing Seam Machine 1282-4 Working Instructions C.5 Beisler Automated Sewing Equipment Maintenance Fig. 15 Setting the rule stop: The stitch width is determined by the width of the pressure foot and by the distance between the pressure foot and the stop. Two versions of the rule stop are available: • Standard rule stop, • automatic rule stop with catch for contour guide. NOTE - Stitch width! The minimum stitch width should not be adjusted using the contour guide settings but by replacing the sewing unit/ pressure foot assembly. If the sewing unit is replaced, the rule stop must be readjusted. Removal and installation of the sewing unit are described in the separate instructions for the sewing head. NOTE - Contour guide positions! Before the rule stop can be set, the start and stop positions in the direction of X/Y must be set correctly. Setting the standard rule stop: 1.

If the transport roller pressure onto the working plate is too high, the cloth layers may be dislocated toward each other during the transport. If thick material is used, the lowering position and therefore the pressure of the transport rollers must be adapted to the material thickness. The three downrollers 2 of the roller unit should exert slight pressure onto the working plate. Fig. 19 Setting the distances of the transport rollers and of the down rollers to the working plate: 1. Lower transport unit manually onto working plate (see Section D, Programming Instructions, Selecting machine control inputs/outputs). 2. Turn machine off. 3. Transport rollers: To adjust distance A between working plate and transport rollers, change the position of the pressure cylinder clamp 3: • Loosen the fixing screw 6 of the clamp 7 and move the clamp along the puller shaft 8. Move clamp upward to reduce the distance or downward to increase the distance. • Check distance A using the cloth material to be processed. The cloth should pe pulled easily under the feed roller 4 and must neither warp nor be pressed against the working plate. After the cloth material has been removed, the feed roller must not touch the working plate. 4. Tighten clamp fixing screw 6. 5. Downrollers: To adjust the distance between the working plate and the downrollers 2, change the position of the pressure cylinder clamp 1 on the shaft: • The roller fork should be lowered so far that the profile 9 of the downrollers shows a distinct pressure surface. - 23 - Beisler Automated Sewing Equipment C.5 Closing Seam Machine 1282-4 Working Instructions Maintenance C.5.5 Machine set-up Fig. 20 Adjusting the stacker motion: The motion of the individual stacker linkages is controlled by the microswitch 2 and by the speed of the pressure cylinder 7. To change the start or end of a motion stage, either the start knop 4 or of the finishing knop 1 is repositioned on the linkage. To control the speed of the motion, the throttles 6 and 8 at the pressure cylinders are repositioned. Fig. 20 Setting the knop positions: 1. Loosen knop fixing screw 3. 2. Reposition knop 4 or 1. 3. Tighten knop fixing screw. Setting the motion speed: 1. To change the speed of the forward motion, rotate the adjusting scew of throttle 7. 2. To change the speed of the rearward motion, rotate the adjusting screw of throttle 6. 3. Directions of rotation: • To increase speed, rotate throttle in counterclockwise direction. • To reduce speed, rotate throttle in clockwise direction. Coordination of the motion: If the microswitch switches early, the linkage strikes. The start knop must be repositioned to achieve a larger distance to the microswitch contactor. If the microswitch switches late, the motion is interrupted. The start knop must be repositioned closer to the microswitch contactor 5. The positioning of the knops must ensure that the finishing knop stops the motion of a linkage after the start knop of the next linkage has actuated the microswitch contactor. The stacker motion consists of six stages: 1. Cylinder 1 pulls up. 2. Microswitch 12 is activated. • Cylinder 2 lifts. 3. Microswitch 32 is activated. • Cylinder 3 throws over. 4. Microswitch 11 is activated. • Linkage return motion starts. 5. Microswitch 22 is activated. • Cylinder 2 lowers. 6. Microswitch 14 is activated. • Cylinder 1 moves back to start position. - 24 - Closing Seam Machine 1282-4 Working Instructions C.5 Beisler Automated Sewing Equipment Maintenance Fig. 21 C.5.5 Machine set-up Regulating the pneumatic air cushion: Six compressed air nozzles 1 around the puller create an air cushion that ensures the low-friction transport of the sewing pieces to the stacker.

Symbol bar 7 The symbol bar indicates the menus that can be selected directly from the start level by using the function keys. All other menus for setting machine or program functions can be selected from the various program levels. The display of the operating panel shows the pertaining menu symbols. -3- Beisler Automated Sewing Equipment D.2 2.1 Closing Seam Machine 1282-4 Working Instructions Program control Program control layout The program control is controlled using three different kinds of menus: 1. Operational menus with direct acces 2. Programming menus 3. Service menus Operational menus The operational menus are used to directly select functions that • allow corrections of the sewing process, • support auxiliary processes required during machine operation, e.g. passing thread through needles, • allow the enabling or disabling of machine functions, e.g. differential feeding or top feeding. Programming menus The programming menus are used for programming sewing programs and pertaining seams: • modifying existing seams, • copying and renaming sewing programs, • programming new seams, • erasing seams. Service menus The service menus are used for managing sewing programs; they offer functions that support the set-up and the testing of the machine: • transmission and storage of data, • input / output tests for the initiators of the compressed air system, • diagnostic tests for motors, • additional programs. Access to some of the service menus and programming menus requires an access privilege that protects the data from unauthorized manipulation. In the service menu, data can only be input or changed after the service code has been entered. If required, the service code can be requested from the machine manufacturer. Menu level structure The operational menus consist of direct access 1 and direct access 2. The programming menus consist of level 1 and level 2. The service menus range from level 2 to level 4. CAUTION - Machine damage! Some of the menu inputs will start individual machine components or a machine cycle. If components have been partially or completely removed or are not operational, machine components may be damaged. Do not input data unless the machine is operational! -4- Closing Seam Machine 1282-4 Working Instructions D.2 Beisler Automated Sewing Equipment Program control Sewing program A sewing program controls the entire machine operation during production: • the routing of a seam, • the sewing of a seam, • the transfer of the sewing piece to the stacker, • the stacking of the sewing piece. A sewing program is determined by three different kinds of values: • Sewing functions Sewing functions are machine components that can be enabled or disabled to perform part of a sewing process, e.g. roller or stacker. • Sewing parameters Sewing parameters are settings that refer only to one particular seam of the sewing program. Changes to the sewing parameters will affect only the currently selected seam of the sewing program for which the setting is made. • Basic parameters Basic parameters are values that control the basic functions of the machine. Changes to basic parameters will result in changes of all stored sewing programs. Sewing programs can be extended, renamed or copied. In a sewing program, at least one seam must be activated. If a sewing program consists of several seams, a subset of seams may be deactivated. Basically, it is possible to create entirely new sewing programs; however, it is usually easier to: • copy a factory-programmed sewing program to a free location in the memory and to modify this program, • copy an already modified sewing program to a free location in the memory and to adapt it further in accordance with the intended purpose. Seam number Each sewing program can be executed with up to five seams. The seams are assigned to the sewing program by seam numbers (1, 2, 3, 4, 5). NOTE - Editing seams Any data changes in the program control, such as • setting parameters, • changing seam names, • copying seams, • erasing seams, always apply to the marked seam of the sewing program shown on the display. -5- Beisler Automated Sewing Equipment D.2 Closing Seam Machine 1282-4 Working Instructions Program control Memory Sewing programs are stored in the memory (M). The program control memory can contain up to 20 sewing programs (M 01-M 20). All sewing programs stored in the memory can be copied and stored to the memory card for data backup. Factory settings Depending on the production type of the sewing pieces, various sewing programs for the program have been preprogrammed at the factory. Programs for trousers production: M 01 Side seam with braid pocket M 02 Side seam with pocket in side seam M 03 Side seam with wing pocket M 04 Crotch seam M 05 Crotch seam with tailor quality M 06 Side seam with seam break before hem (available only for systems with additional thread trimmer feature) Programs for jacket production: M 0I Main seam M 02 Seam break by stitch counter M 03 Seam break by photocell M 04 Thread trimming at beginning of seam, sewing start in sewing piece -6- Closing Seam Machine 1282-4 Working Instructions D.2 Beisler Automated Sewing Equipment Program control 2.2 Menu level overview -7- Beisler Automated Sewing Equipment D.3 Closing Seam Machine 1282-4 Working Instructions Programming 3.1 Operational menus The functions of the operational menus extend over two access levels.
