Replacing a label roll

Detecting end of roll
To keep downtimes during production as short as pos-
sible, the roll should be changed as quickly as possible.
Threading the label material through the entire machine
is relatively time consuming. Threading in can be avoid-
ed by connecting the beginning of the new material roll
to the end of the old material roll (= splicing). This
means that the material end must be detected before it
is too late.
Various functions are provided for detecting the materi-
al end; see section Material end / roll diameter 
page 92.
Remove wound carrier material
The backing paper rewinder can exactly rewind the
amount of backing paper remaining from a material roll
with 300 mm diameter.
CAUTION!
A backing paper roll exceeding the
diameter limit can stall and damage
the machine!

Always remove the backing paper
from the rewinder if you insert a new
material roll.
1. Turn thumb screw loose and swivel guide rod [46A]
aside.
2. Pull out the release button [46B].
The rewider's spreading mechanism is loosened.
3. Remove wound backing paper.
4. Swivel guide rod to the unwinder axle and shift it
close to the material roll. Tighten the thumb screw.
