3._ Material stopper mounting and material stopper
Turn main switch off
- Risk of Injury -
The material stopper mounting 2 must be in a
specific initial position in order to be able to
interchange material stoppers for various seam
configurations without having to make further
adjustments.
At the stopper bolt 5 lying on the stopper there
must be a distance of 88_mm between the front of
the guide pipe_10 and the front edge_1 of the
material stopper mounting 2.
– Loosen nut 4.
– Move the stopper bolt 5 so that there is a gap of
88 mm between the front edge_1 and the
angle_11.
– Tighten nut 4.
The equidistant interval from the seam to the
material edge (seam interval) is determined by the
material stopper 6.
Prerequisite for the setting is that the adjustments
for the right transport carriage end position as per
Section 2.1 and the markings on the rail and
material stopper as per Section 2.3 have been
carried out correctly.
– Loosen screw 3.
– Align the material stopper 6 so that there is an
equidistant seam interval between it and the
material guide rail along their complete length,
e.g. 10 mm.
– Tighten screw 3.
The sewing unit can only be started when the
material stoppers have reached their end
position, this is, when the switch b3 for the left
stopper and the switch b4 for the right stopper
have been activated.
– Turn main switch on.
– Key in Program 63 on the "PROGRAM" switch
and activate with the STOP key. Enter the
number 4 for switch b4.
– Push the stopper all the way to the back until at
rest. - B4+ must appear in the display.
– Should this not be the case then a gap of 0.5
mm must be set between the contact maker 7
and the switch b4. Set contact maker so far
over the switch until B4+ appears.
– Set switch b3 in the same manner.
– The forward and back movements of the
material stoppers should be continuous, not
jerky.
They can be adjusted at the throttle valves 8
and 9.
The right material stopper has an advance function,
this means that when the transport carriage has
passed the right material stopper this then starts its
movement to the front to again position the
material.
The timing is fixed in the controls.
