Operation
4.20 Needle transport
Needle transport improves seam quality in difficult-to-sew and difficult-to-
feed materials such as stretch material, patterned and stripe material,
knitwear, coats and leather goods. The transport length can be individual-
ly adapted to the material and stored in the program.
The needle transport setting varies with the sewing material and the
achieved sewing result.
The needle transport is adjusted using the OP7000 control panel.

4.21 Stepper motor-controlled transport clamp adjustment
with material spreading
Fig. 41: Spreading the transport clamp
The positions of the transport clamps relative to the folder sole can be set
individually and depending on the material in the program. This is made
possible by the automatic conversion from double pipe to single pipe and
program storage to a wide range of material thicknesses.
It is, furthermore, possible to spread the material after lowering the trans-
port clamps in order to achieve better seam quality and more precise
corner cuts.
The setting for the transport clamps is made using the OP7000 control
panel. Program parameters > Process of transport clamp >
