Cutting principle
Production without chip-out (3):
• the upper cutting cylinder (1) cuts the format.
• the lower cutting cylinder (2) is stationary in its resting position.
Production with chip-out (4):
• the lower cutting cylinder (2) cuts the format (= chip-out + format).
• the upper cutting cylinder (1) cuts the chip-out off the front edge of the
format.
Heated side walls • In order to maintain a constant temperature and achieve perfect cut
quality, the side walls of the sheeter unit are actively heated.
• Heating begins when the main switch is switched on.
• The duration of the warm-up phase depends strongly on the respective
ambient temperature.
At an ambient temperature of 18°C, this is approx. 15-20 min .
To ensure that the entire cutting unit is heated evenly, a warm-up
phase of one hour should be observed. This avoids increased
wear on the cutting units
.
• If a temperature of 33°C is not reached, production is not enabled. This
is indicated by a message on the touchscreen.
• Never operate the sheeter when the set temperature has not yet been
reached, otherwise this could result in serious property damage.
• A fluctuation on the temperature indicator during operation is normal
and is caused by the set hysteresis characteristic curve.
