C.5.8 Adjusting the contour guide
The following three adjustments are made for the contour guide.
Height quick adjustment:
Fig. 6: 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 contour guide sliding plate 4 should lower as
far as possible, the fabric should 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 further, rotate the
handwheel 1 counterclockwise.
4. Pull fabric below sliding plate to check
whether the sewing material can pass ea-
sily.
Contour roller clamping pressure:
The pressure that the contour roller 7 ap-
plies is crucial for the continuous guiding of
the sewing pieces along the sewing unit stop
6. The required pressure is determined by
trial and error.
1. Line up sewing piece and start machine
cycle. If the sewing pieces are shifted side-
ways away from the stop, 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.
