3. Manufacture of material clamps
3.1 Determination of seam coordinates
Contour template
Bed-plate for flaps
Bed-plate for waistband extensions
Upon the setting up of the sewing programme, the exact seam contour must be entered in the Dacs739 software. Therefore, the individual coordinate points of the seam contour must be determined
The coordinate points are determined by means of the 0739 410220 contour TAGtemplate included in the “transponder loader” kit.
Position and adjust seam template on the contour template. For adjusting of a flap template see chapter 3.1.1. For adjusting of a waistband extension template see chapter 3.1.2.

Sewing range of diagonal flaps
CAUTION! Risk of damage!
For diagonal flaps, do not sew an angle of less than 45°.
Determine the coordinates for the individual points 1 to 4 and enter the values in the Dacs739 software.
Note
In the Dacs793 “Documents” folder, sample files for frequently used flaps and waistband extensions are saved. The sample files can be edited for the creation of your own designs.
CAUTION!
Prior to editing, save the sample files under a different name.
Files for flaps
flap-1.dac to flap-7.dac
Files for waistband extensions
waist-band-1.dac to waist-band3.dac

3.1.1 Positioning of seam template for flaps on the contour template
12 3
Place flap template 3 onto the contour template.
Align template as follows:
Vertically (A)
The centre of flap 3 is to be positioned at the level of hole 2 for the clamping element 4.
Horizontally (B)
Seam 1 is to run with a minimum distance of 30 mm to the left and right of the clamping elements 4 and 5 respectively.
CAUTION! Risk of damage!
If the distance from the seam line to the clamping elements 4 and 5 is less than 30 mm, there is a risk that the device may collide with the suction device.
Note
Due to the minimum distance of 30 mm to the clamping elements on both sides, the use of two clamping elements is only possible for a flap widths of 100 mm and larger. For flap widths < 100 mm, only one clamping element can be used.

5-10
3.1.2 Positioning of seam template for waistband extensions on the contour template
2
1
Place template 1 centred onto the “88 mm” line of the contour template.
Align template vertically (A):
CAUTION! Risk of damage!
If distance a (see drawing below) is longer than 25 mm, there is a risk of collision with the extraction unit. Shorten lever 2 of the clamping device accordingly and define new location hole.

Note
The distance of the edge of the waistband strip to the stops may vary between 58 mm and 80 mm.

3.2 Transferring contours of material clamp to stitching plates
1
After the sewing programme has been set up by means of the Dacs739 software, contour 1 of the material clamp can be stitched to provide a template.
Note
If the sewing programme is to be tested first, transfer the seam picture to the stitching plate and stitch.
Set up sewing programme. Thereby take into account the position of the sewing piece on the respective bed-plate (see chapters 3.1.1 and 3.1.2).
Place zero gauge with transponder 1 onto the transponder loader. The gauge is included in the delivery of the 739-23 sewing machine.

5-12
Transfer seam contour by means of the Dacs739 software to the transponder.
or
Draw material clamp contour. Select “Objects > Calculate seam template” from the menu. An line that runs parallel to the seam at a distance of 3 mm is created.
Transfer template contour by means of the Dacs739 software to the transponder.
3.3 Transfer of stitching contour to the stitching plate
21
Preparation of sewing machine
Remove cutting device 2 from the sewing machine.
Replace needle 1 with a shortened pointed needle.
Position pointing plate 3 on gauge 4.
Insert gauge in such a way that the pointing plate is positioned below the needle.
Turn needle bar downwards and check the height of the shortened needle (pointer).
The pointer must only touch the pointing plate.
Turn needle bar upwards.
Remove zero gauge.
Pointing of contour
Switch on sewing machine
Press the “OK” key. The sewing machine is referenced.
Place zero gauge on the guide.
Press “S” key. The stitching programme is read. “Pointing” appears on the display. The contour is being pointed.

3.4 Infeed and exit of edge cutter
3.4.1 Infeed and exit of material clamps for flaps
During the referencing of the sewing machine, the edge cutter is positioned parallel to the material clamp guide.
To ensure that there is sufficient room for it to turn at the beginning and at the end of the seam, the bed-plate must be equipped with the respective infeed and exit openings.
For the calculation of the equidistant by the Dacs739 programme, a vertical line is automatically drawn from the sewing start downwards and an additional point 1 is generated. This point 1 is the switch-on point for the edge cutter.

Flap beginning
Draw a straight line from the first stitching point 2 to a point
that is 3 mm to the side of the zero point 3.

Flap end
Clearance 5 is required for the cutting and clamping of the thread.
Draw a vertical line of 30 mm from the last stitching point 4 downwards. Draw a horizontal line from the endpoint of this line to the edge.
The two lines may also be joined by a curved line.

End of waistband extension
Clearance 5 is required for the cutting and clamping of the thread. –
Draw a vertical line of 20 mm (for a radius of 10 mm) from the last stitching point 4 downwards. Draw a horizontal line from the endpoint of this line to the edge.
The two lines may also be joined by a curved line.

3.5 Trimming of bed-plate, intermediate sheet and clamping plate
43 21
Place bed-plate 4, intermediate sheet, clamping plate and pointing plate on top of each other and secure with two countersunk screws, washers and nuts. For flaps, put screws through holes 1 and 3, for waistband extensions put screws through holes 2 and 3.
Note
If the contour runs through one of the holes 1, 2 or 3, first assemble the package and drill a new hole with a diameter of Ø 4 mm through all four plates.
Cut out contour.
Deburr contour.
5-16
5
Produce edge crimp 5 of approximately 1.5 mm at the base side of the bed-plate near the seam line.
3.6 Manufacture of fullness plates
The fullness plate 1 is also calculated by the Dacs739 software. –
Generate fullness contour. Select “Objects > Calculate fullness contour” from the menu.
Place zero gauge with transponder onto the transponder loader.
Transfer fullness contour by means of the Dacs739 software to the transponder.
Transfer fullness contour to the stitching plate as described in
chapter 3.3.
Cut fullness plate to size.
Deburr the edges of the fullness plate.

Material position
Measurements in mm
The bed-plate and the clamping plate are already equipped with holes 1 and 2 for a clamping element. Hole 2 should be positioned on a line going through the centre of gravity of the material clamp contour. If the preset position does not fulfil this requirement, new holes must be drilled.
Define position of clamping elements. The length of B depends on the width of the flap.
Indicate holes on the bed-plate and the clamping plate (for
dimensions, see drawing).

1
Measurements in mm
The bed-plate and the clamping plate are already equipped with holes for the clamping element. Depending on the handling, the clamping element can be positioned to the right or the left respectively.
If the preset holes 1 are not appropriate (collision with the suction pipe), the tension lever can be shortened and new holes can be drilled into the clamping plate and the tension lever.
Note:
Install tension lever to the left or right, depending on the handling.
