Loading positions for hind trousers parts
–
Hind trousers can be positioned according to two methods:
a) symmetrical at the central light spot 2 (according to the dart)
b) according to the positioning marks 4 or 8
–
Align the end of pocket opening 7 preferably at the rear light spot
3.
The hind trousers parts should be positioned as close as possible
to the operator. Thus, the hind trousers can - after positioning - be
safely smoothed out when the feeding clamps move forward.
