Set stopper screw 3.
When the flap feed is swung in during the work cycle, it lays on
tight on the gripping folder. In order to avoid whipping and thus a
displacement of the flap in the clamps, the flap feed must lay on
forward.
–
Set the flap support.
Loosen screws 9 and 10.
In the swung-back position the edge of the flap support 5 should lie
parallel with the edge 2 of the aligning plate.
–
Tighten screws 9 and 10.
–
Set the stop 8.
The aligning plate 1 should not strike under the flap support 5
when swinging back.
The sewing area of the sewing unit is established at max. 180 mm and
set accordingly at the factory. The marker lights and the stops 4 and 7
are set correspondingly to the seam beginning and seam end.
–
Check the setting of the stops 4 and 7.
If the flap edge is positioned exactly on the light marker, then, with
the flap held clamped and the device swung out, the flap edge 6
must lie exactly at the level of the stop 7.
The same applies analogously for stop 4.
Note
A pattern-perfectly aligned flap should not be pulled out of its position
when taken up by the flap feed 11.
This leads to an imprecise sewing result !
–
Set cylinder 14.
The cylinder 14 must press the opened flap feed 11 down so far
that the flap can swing in securely and unimpaired.
When the flap feed closes the flap should not be pulled out of its
position or strongly buckeled.
The lower clamp 12 must build one level with the flap support 13.
–
Set the cylinder 15, flap clamps, stops and shock absorber as
described in Chapter 5.
