- Risk of Injury -
With curved material guide rails the guide rod 2 is
moved within an allowable range crosswise to the
direction of sewing.
The range is properly set if there is a distance of
135 mm between the transport carriage 3 and the
clamping piston 4 when the guide rod 2 is pulled to
its rest at the front of the unit.
For a perfect laying-on of the rail the guide rod
must be set tight and parallel to the table top.
– Loosen the clamping piece 8 and set the
dimension 135 mm.
– When tightening the clamping piece 8 take care
that the stroke cylinder 1 is vertically aligned.
– Measure the distance to the material slider bed
with the guide rod 2 in its forward and rear
positions.
– Should the distances not be equal, first loosen
the guide beads 6.
– Achieve parallelism of the guide rod 2 by
adjusting the excentrically bearinged guide
rollers 5.
This is to be performed appropriate to the
measurement results so that first one of the
rollers is loosened and turned slightly.
The transport carriage is to be held tight by the
second roller.
– Set the guide rails 6 tight on roller 7.
Take care that the guide rod can still be easily
moved.
The left guide rod is to be adjusted in the same
manner.
