Closing Seam Machine 1282-4 Working Instructions

B.2.1 Functional

The CLOSING SEAM MACHINE 1282-4 allows the contour-identical sewing of front and rear trousers components in side and crotch seams. 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.

of the machine

Fig.2

B.2.2 Lining up/aligning trousers components 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 unit4.

Machine cycle:

Insertion process and machine cycle are effected from left to right:

• The trousers components are lined up to guide clamp

, 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. 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 needle6 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.

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.

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 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.

Closing Seam Machine 1282-4 Working Instructions

Fig. 5

This setting ensures the easy gliding of the trou-

sers 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 guide1 for the line-up of the front trousers component. This feature is available only in connection with the optional pneumatic rule guide.

B.2.3 Transport and sewing

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 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).

Fig. 6

NOTE - Reflective film

The reflective area 3 of the photocell must not be damaged as otherwise a failure of the sewing unit will occur.

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.

Stacker, Fig. 8:

The stacker 1 stacks the tucked trousers components.

B.3.8 Starting machine cycle

A machine cycle can be started in three different sequences (mode 00, mode 01, mode 02). The factory default is mode 00.

Controlling machine cycle in mode 00, Fig. 16:

Mode 00 starts a fully automatic machine cycle that is controlled by the photocell.

1. Insert the trousers components into the guide clamp and line them up over the contour guide at the pressure foot.

2. As soon as the cloth material interrupts the light beam of the photocell at the reflective film 1, the machine cycle starts. The photocell responds with a delay whose duration can be set individually using the program control.

• The trousers components are routed along the guide rail to the contour guide.

• The contour guide controls the routing of the seam.

• The sewing unit sews the overlapping components to each other.

•The sewing process is completed as soon as the trousers components have passed the reflective film of the photocell.

• The roller unit pulls the sewing piece from the worktable to the stacker.

•The stacker stacks the trousers components.

Controlling machine cycle in mode 01: Mode 01 starts a combination of manually controlled seam and subsequent automatic machine cycle that is

controlled using the pedal.

1. Insert the trousers components into the guide clamp

and line them up over the contour guide at the pressure foot.

2. Pressing the right side of the pedal 2 starts the se-

wing process. The sewing speed can be controlled in twelve stages, depending on the pressure that is exerted. The higher the pressure, the faster the speed. Using this control, the seam can be controlled manually for complicated sewing stages.

3. The automatic machine cycle can be started by pres-

sing the left side of the pedal 1 at any position of the seam.

• The remaining seam dist ance is effected along the guide rail to the contour guide.

• The contour guide controls the further routing of the seam.

•The sewing unit sews the overlapping components to each other.

• The sewing process is completed as soon as the trousers components have passed the reflective film of the photocell.

• The puller pulls the sewing piece from the workt able to the stacker.

• The stacker stacks the trousers components.
