7. Transfer carriages
7.1 General information
The transfer carriages , moved by 2 motors in X and Y direction, have
following duties:
–
Transporting the material by means of the transfer plate from the
folding station to the sewing station.
–
Moving the material during the sewing process according to the
seam outer contour
Following static traction forces of the X and Y carriage can be used for
trouble shooting. The values acquired are measured by a spring
balance.
X carriage without belt drive about. 70-80 N
Y carriage without belt drive about. 70-80 N
The sewing result can be improved by the following constructive
measures:
–
Owing to the parallel-action joint, the transfer plate is more or less
parallel to the working surface also in lifted position. Consequently,
no displacement of the fabric of different thickneses by the transfer
carriage.
–
The rubber springs of the reception fork care for compensation of
any irregularities in the material. Therefore, same fabric pressure
at all parts.
7.2 Adjusting the parallelism of the transfer plate
Rule and control
The transfer plate must be parallel to the table top surface when it has
been lowered and depresurized.
Correction
–
Regulate the adjustment screw in the bore-hole 1 accordingly.
