Maintenance
Check and, if necessary, adjust the cutting
gap/clearance of the channel guide
The press body (see fig. 88) is guided by
sliding bearings horizontally and vertically
in the press channel. The height of the
press body can be adjusted by means of
different adjusting screws..

Experience shows that wear and tear of
the bearing is very low and there is thus
little need to adjust them. During the 2‐
month's running‐in time the cutting gap
should be checked once a week. After the
running‐in time proceed according to the
appropriate interval in the maintenance
schedule.
Failure to observe this notice may result in
the side edges of the press body and those
of the channel coming into contact. This
results in score groves on the parts which
touch. The functioning and service life of
machine are not normally affected by
these. However, the resulting roughness
means that material will enter this gap.
7.4.16 Adjustment press body, press
channel and cutting gap: check and adjust
if necessary
A correct side guide is very important
otherwise jams will occur. The cutting gap
as well has to be correctly adjusted
otherwise severe damages may occur. A
cutting gap of less than 1 mm is set at the
factory. Ensure that, if at all possible, this
value is not exceeded. A cutting gap which
is too large or, respectively, blunt knives
may in the worst possible case result in
the press face becoming blocked.
A too big cutting clearance (>2mm) in
connection with blunt cutting edges (edge
radius >0,5mm) and appropriate material
behaviour (e.g. foils, PET o.s.) results in
vertical force introductions into the
housing structure which could add a
multiple of the thrust of the pressing ram.
Thus severe damages (cracks, permanent
deformations) can be caused.
