Checking the transfer process
The schematics to the right display the typical transfer
process: from dispensing the label to transferring the
label to the product.
1. Once a print or dispensing command is received,
the label is transferred across the dispensing edge
[32a] and separated from the release paper [32b].
The label is transferred closely past the edge of the
vacuum plate [32c].
The amount of bending in the label depends on the
following factors:
– Feed speed
– Adhesive force
– Label thickness
– Room temperature
If the label is not deflected far enough to come
past the vacuum plate, adjust the height setting
of the dispensing edge. See chapter
Adjust the
distance to the dispensing edge

on page 21.
2. The support air [32d] deflects the label away from
the vacuum plate.
For more information, see chapter
Adjust the
vacuum at the pressure plate

on page 24.
3. The label is ‘caught’ by the vacuum plate and
moved along by the feed force. The suction force of
the vacuum plate must not exceed the feed force
for the label. Here, it is important to consider the in-
teraction between feed force, support air angle,
support air force and suction force.

support air

on page 24.
4. Once the label has separated completely from the
dispensing edge, it snaps onto the vacuum plate.
The distance to the dispensing edge prevents the
label from adhering during the downwards move-
ment of the vacuum plate towards the final position.
5. The vacuum plate is pushed downwards to the final
position and the label is transferred onto the prod-
uct.
