4. Clearance of the Transport Clamps to the Folder Sole

4.1 Manual Adjustment of the Transport Clamps (745-22)

16
There must be a certain clearance between the outer edges 2 of the
folder sole and the inner edges 1 of the transport clamps. By medium
weight cloth for ready-made clothes it must be e.g. 1 to 1.5 mm.
The clearance is necessary in order to assure uniform piping widths on
both sides and an unhindered transport of the material.
With the 745-22 and 745-24 both transport clamps are set by turning
the Allen screws 6.
With the 745-23 only the right transport clamp is set manually.
The scale plates 8 serve as setting aids.
–
To set the clearance turn the Allen screw 6. To turn use the socket
wrench 5 to be found in the accessories pack.
–
The scale plates 8 were aligned at the factory as follows:
When the pointer 7 points to the marking "I" the correct clearance
for sewing medium weight material of two-sided piped pocket
openings is set.
The second marking gives the clearance for sewing a greater
piping width or a one-sided piped pocket opening.
–
By stepping forward or back on the left pedal conduct test runs
with the transport carriage.
The transport clamps must pass the guide plates 4 and the thread
catcher 3 unhindered.
ATTENTION !
The markings on the scale plates 8 are matched to the needle
clearance of the machine head.
When attaching needle holders for other needle clearances the scale
plates 8 must also be replaced.
Pneumatic quick clamp adjustment
By frequent changes of the folder between single and dual piping the
pneumatic quick clamp adjustment simplifies the setting of the
transport clamps.
With the 745-23 the left transport clamp has the pneumatic quick
clamp adjustment as standard equipment (Description see
Chapter 4.2).
With the 745-22 and 745-24 it is available as optional equipment
(Order no. 792 005981).
