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  on
page 85.
