4.12 Adjustment for loop-stitching, wire length stitching thickness - stitching table
4.12.1 Adjusting the wire length
According to Chapter 4.4 with the following setting:
• The number determined from the material to be stitched -37- is read off on the right stitching
thickness scale -39-, and set on the left wire length scale -42-, increased by a value of 5 mm.
Example: Reading on stitching thickness scale 39 = 2 mm
Setting on the wire length scale 42 = 2 mm + 5 mm = 7 mm
After the first presetting, the wire length must be precisely adjusted by means of test stitchings.
4.12.2 Adjustment of the stitching thickness
Equal to standard folder stitching
4.12.3 Adjustment of the stitching table and limit stops
- Fig. 4.13 -
The procedure is explained by means of an example:
• A folder has to be stitched with two loops, distance 80 mm (measured from middle) to the middle
of the loops.
• The length of the folder is 210 mm; locate the middle of the back edge with a division mark, i.e.
at 105 mm.
• The folder is placed on the tilted table, so that the middle of the driver and the division mark of
the folder exactly coincide.
• Set the right and left limit stops on either side of the folder to a distance of 40 mm.
• The folder is stitched, pushing first to the right, then to the left limit stop. The distance of 80 mm
measured from the upper and lower edge of the folder corresponds to the distance between the
two loops (middle to middle).
Check equal length of folders before stitching!
Note:
Check distance and execution by means of a specimen folder! Tighten the
knurled screws of both limit stops carefully, to avoid differences in stitching
distance.
