Dancer arm adjustment
Depending on the label format, the retraction force of the dancer arm can be reduced or
increased. If, under certain circumstances, very narrow label material tears or stretches to
such an extent that the dispensing accuracy fluctuates, it is advisable to reduce the force
of the dancer arm. Conversely, a stronger force can be advantageous for very wide label
material.
With the adjusting handle (pos. 2, Fig. 7-1) the retraction force can be adjusted in two
stages, stage 1 corresponds to the lowest and stage 2 to the highest force setting.
