C.5.8 Adjusting the contour guide
The following adjustments are made for the contour guide:
Height quick adjustment:
Fig. 7: Use the handwheel 2 of the four-stage quick adjustment for
the rough adjustment of the material thickness. With each additional
stage, the distance between the sliding plate and the working plate
increases by a fixed value of 0.8 mm. The selected stage is indicated at
the hand-wheel.
Stage 1 0.8 mm
Stage 2 1.6 mm
Stage 3 2.4 mm
Stage 4 3.2 mm
Height fine adjustment:
The adjustment made with the height quick adjustment 1 can be fine-
adjusted using the height fine adjustment 2. The following should be
observed as a rule: The sliding plate 4 should lower as fas as possi-
ble, the fabric must pass easily below the sliding plate.
1. Slide the sewing material below the sliding plate.
2. Push the sliding plate manually
down all the way to the stop.
3. To lower the sliding plate even fur-
ther, rotate the handwheel 1
counterclockwise.
4. Pull fabric below sliding plate to
check whether the sewing material
can pass easily.
Contour roller pressure:
The pressure that the contour roller
6 applies is crucial for the conti-
nuous guiding of the sewing pieces
along the sewing unit stop. The requi-
red pressure is determined by trial and
error.
1. Line up sewing piece and start ma-
chine cycle. If the sewing pieces
are shifted sideways away from the
stop 7, the pressure is too low;
rotate adjusting screw 3 counter-
clockwise to increase the pressure.
2. If the sewing pieces warp at the stop, the pressure is too high; rotate
adjusting screw 3 clockwise to reduce the pressure.
3. The pressure of the blowing unit 5 should remain unchanged.
