Unwind unit
– A loop forms in the loop space as a buffer between
the unwind unit and label dispensing,
ALS 350: [44 arrow], ALS 450: [45 arrow].
– A photoelectric sensor in the loop space monitors
the loop.
– If the loop becomes too large, the control system au-
tomatically slows the unwinding speed. The dis-
pensing speed does not change.
– ALS 450: The dancer arm swings approximately into
the centre position [45B].
Rewind unit
– The multiple deflections with the spring-loaded
dancer arm act as a buffer between the label output
and the rewind unit. During operation, the dancer
arm swings between the horizontal and its upper
end limit,
ALS 350: [44A], ALS 450: [45A].
– If necessary, the control system automatically slows
the rewinding speed. The dispensing speed is not
affected by this.
