9.2 Adjustments
9.2.1 Spirals
It is possible to modify the position of the spiral end by pulling it
forwards until the geared motor panel comes out.
Rotate the spiral until the ideal position is found.
Release the spiral which will return to its housing because of the
spring effect.
Each spiral can rotate by 45° at a time (see fig.9.3)
9.2.2 Spiral replacement
It is possible to replace the spirals with others with a pitch that is
suitable for the product to be delivered. To carry out this operation,
proceed as follows:
- rotate the spiral in a clockwise sense until it is released on the
dragging cam (Fig.9.4)
- bend the spiral downwards slightly and pull it outwards.
For reassembly:
- couple the spiral behind the notch on the cam (Fig.9.4-pos.1).
- introduce the spiral in the slot on the cam (Fig.9.4-pos.2).
