B.2.1 Operating principle and machine cycle

Operating principle:

The automatic single-head serging machine 1265-4 allows the automated serging of inseams and side seams of trousers panels, with or without knee lining. The sewing unit automatically sews and serges cleans the fabric contour and incorporates the fullness for the knee lining, if required. The trousers panels are sewn in separate machine cycles:  the inseam or side seam of the rear trousers panel,  the inseam or side seam of the front trousers panel with knee lining on

 the inseam or side seam of the front trousers panel with knee lining on

top,

bottom.

NOTE - Applications

The machine has been designed predominantly for serging trousers panels. However, it can also be used for processing other sewing pieces, e.g. sleeves, short trousers, etc.

Machine cycle, Fig. 2:

The short seams can be serged manually at the sewing head 2 prior to the sewing of the inseam or side seam.  The trousers panels are stocked on the upper tray

, the knee linings are stocked on the lower tray

. The trousers panel is placed onto the working plate, the corresponding knee lining is aligned to the trousers panel with the hems being flush.

 At the optional bonding station 6, the front and

rear trousers panels can be secured to each other using a bonding mesh.

 Both trousers panels are routed below the con-

tour guide 3 and lined up at the stop of the sewing head 2. A photocell starts the sewing process. The fully automatic machine cycle is started.

 During the sewing process, the contour guide 3 and the puller of the

transport unit 7 control the routing of the seam.

 If required, the top and bottom transport units of the sewing unit incor-

porate fullness.

 The transport unit 7 transports the sewing piece from the working plate

to the stacker 8 where the sewing pieces are stacked on top of each other.

 As soon as the sewing process starts at the sewing head 2, the next

trousers panels can be secured at the bonding station.

B.2.2 Securing the sewing pieces

Bonding station, Fig. 3:

To prevent the trousers panel and the knee lining from being shifted during the sewing process, they are secured to each other by hot pressing at a lateral location. At the bonding station 1, a bonding mesh strip 3 is placed between knee lining and trousers panel and heated by the lower stamp 4 of the press unit. Then, the upper stamp and the lower stamp press the sewing pieces together so that they are secured to each other.

B.2.3 Guiding of the sewing pieces

The guiding of the sewing pieces along the stop of the sewing head is controlled by the combined action of contour guide and puller.

Contour guide, Fig. 4:

Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH

Functions of the machine

During the transport of trousers panel and knee lining to the sewing unit, the contour guide controls the shape of the fabric contour and ensures the exact routing of the seam along the sewing stop 6 of the sewing unit. At the contour guide, the following settings are made for the thickness of the fabric:  Height quick adjustment 1 of

the contour guide:

Use this control for the rough ad-

justment of the thickness.

The distance between the con-

tour guide sliding shield 4 and

the working plate can be chan-

ged in four stages of 0.8 mm

each in both directions.

Stage 1: smallest distance

(0,8 mm)

Stage 4: largest distance (3.2

mm)  Height fine adjustment 2 of the contour guide:

The rough adjustment made with the height quick adjustment can

be fine-adjusted. The following should be observed as a rule:

A single fabric layer should pass easily below the sliding plate

while a double layer must not be allowed to pass through the gap.  The pressure that the contour roller 7 applies to the sewing pie-

ces is set with the adjustment screw 3. The setting of the compressed-air nozzle 5 that blows the sewing pieces against the stop should not be changed to adjust the contour control.

Fig. 4

Stop:

The standard version of the machine has a stop that is secured to the contour guide. Optionally, the machine can be equipped with a pneumatic stop. With this option, a pocket pouch can be inserted between trousers panel and lining and serged. In this case, the seam section to the end of the pouch is sewn manually, the remaining section of the seam is sewn fully automatically. The section that is sewn manually is determined by parameter 10 of the sewing function STATION CLOSE. At the end of this section, the transport unit is lowered, the pneumatic stop moves to the pressure foot, and the contour guide controls the seam.

B.2

Control, Fig. 5:

The control of the sewing pieces along the sewing stop is affected by:  the puller speed 4,  the pressure that the contour

roller 3 applies to the se-

wing pieces. The photocell 1 determines the deviation of the fabric contour 2 from the ideal routing at the reflective film and readjusts the speed of the puller 4 as required.  If the sewing pieces are shif-

ted sideways away from the

stop, the puller speed is too

high,  if the sewing pieces warp at

the stop, the puller speed is

too low. The frequency for adapting the puller speed is set with the program control. In addition, the contour roller 3, due to its orientation, pushes the sewing material toward the stop. The lateral thrust depends on the pressure that the contour roller applies to the sewing pieces:  If the sewing pieces are shifted sideways away from the stop, the

pressure is too low,  if the sewing pieces warp at the stop, the pressure is too high. The required contour roller pressure is determined in sewing tests in combination with the puller speed.

B.2.4 Serging the seam

Sewing head, Fig. 6:

The reflective surface 3 of the photocell must not be damaged or dirty as otherwise the sewing unit control may be impaired.

Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH

Functions of the machine

The sewing head performs the sewing, thread cutting, and serging functions. As soon as the photocell 2 recognizes the sewing pieces 1 (the reflective surface 3 of the photocell is concealed by the sewing piece), the sewing process starts:

 the trousers panel is sewn,  the knife 5 serges the seam,  the thread and fabric residues are aspired into

the waste container.

NOTE - Reflective surfaces

B.2.5 Width distribution for knee lining

To ensure the correct width distribution, the transport characteristics of differential transport and top transport must be matched to fit the material of the knee lining.

Presetting, Fig. 7:

In the sewing range of side seam A and inseam B, the trousers panel splits into five sections with the knee lining C extending over four of these sections. For each section, the length can be varied and the pertaining fullness (quantity) can be preset with the program control (see Section D, Programming Instructions).

Quick adjustment, Fig. 8:

The operating panel allows direct access for the quick adjustment of the fullness by modifying top transport 2 and differential transport 1. Select the corresponding function and modify it in a range between -19 and +19 (see Section D, Programming Instructions).

B.2.6 Transport

Transport unit, Fig. 9:

Operating Instructions Automatic Single-Head Serging Machine 1265-4Beisler GmbH

Functions of the machine

The transport unit consists of puller 2 and roller 5.  The puller transports the sewing pieces

during the sewing process and uses its rotational speed to support the control of the fabric contour.

 The roller 5 moves the sewing pieces

beyond the worktable edge and also supports the transport function of the puller. This additional transport function can be enabled for heavy fabrics.

To improve the gliding characteristics of the trousers panels, the working plate has six compressed-air nozzles 1 in the sewing head area. The air blows from below against the trousers panels; the resulting air cushion reduces friction during the transport.

In the sewing range of the side seam hip curve, the position of the strut

is altered to rotate the trousers panel for the sewing process.

B.2.7 Stacking

Stacker, Fig. 10:

As soon as the chain has been severed and the roller has transported the sewing pieces beyond the worktable edge, the automatic stacker is activated and deposits the sewing piece 2 over the bundle rod 1.

Preseams:

Hem seams, fly seams, and hem seams can be serged separately. The characteristics of the preseams are set in a separate parameters list. These settings are used only if the sewing program for preseams is activated.

Inseams and side seams:

Inseams and side seams can either be serged in individual, separate sewing processes or effected as a combined sewing process with alternating seams. In this case, the corresponding preprogrammed seams are enabled in quick access at the operating panel.

Creating identical stitch images:

If identical stitch images are required for inseams and side seams, the knee lining must always be lined up in the same position (always top or always bottom). In this case, the trousers panel is lined up alternatingly flush with the waistband and flush with the hem.

NOTE - Transport roller orientation

After the toothed belt has been replaced, the distance between the transport rollers and the working plate must be checked.

C.5.7 Adjusting the transport rollers

Fig. 5: The transport rollers of the puller 9 and of the roller 2 should

contact the working plate with slight pressure in the lowered position (i.e. distance must be zero in the lowered position). The pressure that the transport rollers apply to the working plate is controlled by a pressure reducer (see Section C.12)

Setting the distance between transport rollers and working plate:

1. Lower the transport unit manually onto the working plate as described in Section D, Programming Instructions.

2. Switch the machine off.

3. To avoid contact between the working plate and the transport rollers, adjust the position of the pressure cylinder clamps 4 and 8 on the corresponding spacer shaft 5 and 7:  Loosen the clamp locating screw and shift the clamp on the spa-

cer shaft. Slide clamp up to reduce the distance, slide clamp down to increase the distance.

C.5.8 Adjusting the contour guide

The following three adjustments are made for the contour guide.

Height quick adjustment: Fig. 6: Use the handwheel 2 of the four-stage quick adjustment for

the rough adjustment of the material thickness. With each additional stage, the distance between the sliding plate and the working plate increases by a fixed value of 0.8 mm. The selected stage is indicated at the hand-wheel.

Stage 1 0.8 mm Stage 2 1.6 mm Stage 3 2.4 mm Stage 4 3.2 mm

Height fine adjustment:

The adjustment made with the height quick adjustment 1 can be fineadjusted using the height fine adjustment 2. The following should be observed as a rule: The contour guide sliding plate 4 should lower as far as possible, the fabric should pass easily below the sliding plate.

1. Slide the sewing material below the sliding plate.

2. Push the sliding plate manually down all the way to the stop.

3. To lower the sliding plate further, rotate the handwheel 1 counterclockwise.

4. Pull fabric below sliding plate to check whether the sewing material can pass easily.

Beisler GmbH

Contour roller clamping pressure:

The pressure that the contour roller 7 applies is crucial for the continuous guiding of the sewing pieces along the sewing unit stop

. The required pressure is determined by

trial and error.

1. Line up sewing piece and start machine cycle. If the sewing pieces are shifted sideways away from the stop, the pressure is too low; rotate adjusting screw 3 counterclockwise to increase the pressure.

2. If the sewing pieces warp at the stop, the pressure is too high; rotate adjusting screw 3 clockwise to reduce the pressure.

3. The pressure of the blowing unit 5 should remain unchanged.

The sensitivity of the photocells must be adjusted to match the sewing material used. The adjustment is made using a white cloth at the photocell that starts the sewing process.

1. Fig. 7: Ensure that the light beam of the photocell is not interrupted by objects.

2. Adjust the sensitivity so that the light beam recognizes the white cloth when it is moved into the sensor area.

3. Rotate potentiometer 1 and 5 at the photocell face counterclockwise to minimize the sensitivity.

4. Increase sensitivity gradually; after each change, move white cloth into sensor area. When the sensitivity threshold limit is reached, the photocell darkens, and the machine cycle starts.

C.5.11 Adjusting the kettup knife and stop

The standard version of the machine is equipped with a stop that is secured to the contour guide. Optionally, the machine can be equipped with a pneumatic stop.

Fixed stop: Fig. 8: The contour guide stop 3 must be offset

slightly at a distance A of 0.2-0.3 mm in front of the chain cutter knife. The knife must cut thread and fabric residues, but not the sewing piece hem. To adjust this offset, the entire contour guide is shifted on the cover plate which is installed loosely into the working table recess and secured by magnets.

1. Lift cover plate with contour guide.

2. Remove the two contour guide retaining screws

at the front of the cover plate; loosen the contour guide retaining nut 4 at the rear of the cover plate only enough to shift the contour guide.

3. Reinstall cover plate and shift contour guide so that the distance A (between chain cutter knife and stop 3) is approx 0.2-0.3 mm. Check distance using a feeler gauge.

4. Tighten the two retaining screws 5 at the front of the cover plate.

5. Remove cover plate and tighten the contour guide retaining nut 4.

6. Align pressure foot 1 to stop 3. Loosen pressure foot locating screw, push pressure foot close to stop, then tighten locating screw. The distance B between pressure foot and chain cutter knife should be approx 0.5 mm.

Pressure foot pressure:

When sewing front trousers with knee lining, the trousers panel can be sewn with the knee lining either on top or at the bottom. While the knee lining is sewn, the pressure that the pressure foot applies to the sewing pieces changes temporarily and then returns to the normal value. The two pressures are set seperately using the rotary knobs.

1. If the lining is on top, the pressure applied to the sewing pieces while sewing the knee lining is reduced. Use the rotary knob 1 to set the pressure to 0.1 mPa and check the pressure at the manometer 2.

2. If the lining is at the bottom, the pressure applied to the sewing pieces while sewing the knee lining is increased. Use the rotary knob

to set the pressure to 0.25 mPa and check the pressure at the

manometer 2.

Beisler GmbH

Fig. 10

Compressed air nozzles:

To improve the gliding characteristics of the sewing pieces, the working plate has six compressed-air nozzles near the sewing head. The air blows from below against the sewing pieces; the resulting air cushion reduces friction during transport. The pressure depends on the weight of the material used. It is set using the valve 4 and must be determined by trial and error.

Transport unit clamping pressure:

The pressure that the transport rollers apply to the working plate is controlled using a pressure reducer. It can be matched to fit the thickness of the material used. The pressure is set using the valve 5 and must be determined by trial and error.

C.5.14 Adjusting the stacker control cams

Fig. 12: The motion sequence of the individual stacker linkages is con-

trolled by the roller valve 1 and by the speed of the pneumatic cylinders 7.  To change the beginning or the end of a motion section, the position

is shifted along the start cam 4 or along the closing cam 5 on the linkage.

 The speed of the motions can be changed using the throttles

and 8 at the pneumatic cylinders.

Changing the cam position:

1. Loosen the locating screw 2 or 3 of the corresponding cam.

2. Shift the start cam 4 or the closing cam 5.

3. Tighten the locating screw.

Beisler GmbH

Setting the speed of the motion sequence:

1. To change the speed of the forward motion, rotate the ajusting screw of throttle 6.

2. To change the speed of the rearward motion, rotate the adjusting screw of throttle 8.

3. Directions of rotation:  Rotate throttle counterclockwise to increase the

speed.

 Rotate throttle clockwise to reduce the speed.

Coordination of the motion sequence:

If the roller valve switches early, the linkage strikes. The distance between the start cam and the roller valve contact 5 must be increased. If the roller valve switches late, the motion sequence is interrupted. The distance between the start cam and the roller valve contactor must be reduced. The positioning of the cams must ensure that the closing cam switches the motion of a linkage off when the start cam of the subsequent linkage has actuated the contact at the roller valve. The motion sequence of the stacker consists of six steps:

1. Cylinder 1 picks up.

2. Roller valve 12 is activated.  Cylinder 2 lifts.

3. Roller valve 32 is activated.  Cylinder 3 throws over.

4. Roller valve 11 is activated.  Linkage rearward motion starts.

5. Roller valve 22 is activated.  Cylinder 2 lowers.

6. Roller valve 14 is activated.  Cylinder 1 returns to basic position.

2.1 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.

 allow the enabling or disabling of machine functions, e.g. differential

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.

transport or top transport.

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!

Program control

D.2

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.

D.2

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

The program control has ten factory-installed sewing programs.

Functions of special parameters:

v Top transport w Differential transport

To ensure correct width distribution, the transport characteristics of differential transport and top transport must be fit to match the material of the knee lining. This is required when waved lining is sewn. For this purpose, the quick adjustment can be used to change the orientation of the differential transport unit or of the top transport unit to the sewing unit in a value range of -19 to +19. This setting affects

only the section of the seam for which fullness has been activated.

Fig. 5: Splitting the seam into sections:

Within the sewing range, the trousers panel splits into sections:  Side seam A with basic setting

S1 - S4 = 15 cm, S5 is the remaining trousers length.

 Inseam B with basic setting S5 -

S2 = 10 cm, S1 is the remaining trousers length from photocell 15 to the knee lining (usually approx 6-7 cm). This section is determined by trial and error for each sewing piece.

 The knee lining C extends over

four of these five sections.

For each section, the length can be varied and the pertaining fullness (quantity) can be preset with the program control.

Fig. 5

Changing the fullness by accessing the complete parameter list of the sewing function.

Basic setting:

When this menu is opened, the input field 3 of the basic setting parameter is activated (i.e. it appears on a black background) and can be changed. If none of the individual sections has been activated, the fullness (quantity) of the basic setting refers to all five sections. Fig. 6: The first section 1 is deactivated, the other four sections 2 are activated (sections 2-5 appear on a black background and are marked as active).

Functions:

 An individual section is activated or deactivated by pres-

sing the function key below it 4.

 The function SLOW (available for differential transport

only) or PRESSURE (available for top transport) is activated by pressing function key F1 6 and the key for the corresponding section at the numeric keypad (each activated section appears on a black background). Use the F2 key 5 to change the seam pattern.
