TARTUP AND OPERATION
Setting the return force of the linear
dancer lever
The linear dancer lever is set so that a wide range of la-
bel materials can be processed without having to
change the setting of the dancer lever return force.
Adjusting the return force:
1. Pull out the knob [40A].

The knob is under spring tension. Hold onto the
knob firmly until it locks into place again.
2. Turn the knob (pulled out) to the desired position.
Adjustment range: 355° (i.e. slightly less than ½
revolution in each direction)
3. Carefully release the knob and allow it to lock into
the desired position.

Do not release the knob until it has locked into
position.
Reducing the return force
Very narrow label material may tear in some circum-
stances or may be stretched so much that dispensing
accuracy is impaired. If this happens, the dancer lever
force must be reduced:
 Turn the knob in direction "–".

The direction of rotation for "–" is opposite on LH
and RH machines:
•
RH: turn anti-clockwise
•
LH: turn clockwise
Increasing the return force
In some cases the label belt may "flutter". This means
that the dancer lever is stretching the label belt be-
tween the dancer lever roll and the dispensing edge too
slowly. If this happens, the dancer lever force must be
increased:
 Turn the knob in direction "+".

The direction of rotation for "+" is opposite on LH
and RH machines:
•
RH: turn clockwise
•
LH: turn anti-clockwise
