Foot switch (3), snap switch;
Press and hold the switch to start the rotation of the rolls. Insert the forefoot completely to
disable the safety lock that prevents accidental starting.
When the switch is released, the rotation of the rolls will stop.
Nip setting wheel (4), geared wheel;
Turn the wheel clockwise to narrow (close) the nip and increase the pressure or
counter-clockwise to decrease the pressure and widen (open) the nip.
When both rollers touch the materials, the pressure is set.
The nip setting is indicated on top of the cabinet and the pressure is indicated by led's on
the control panel.
Unwind/wind-up tension control (5), knob;
By turning this knob clockwise an amount of friction is set between the shaft and
the frame, so this will act as a unwind brake.
Turning the knob counter-clockwise will release the brake.
Turning the knob further counter-clockwise will set an amount of friction between
the shaft and the driving sprocket wheel, so this will act as a coupling between
motor and shaft. The shaft will now act as a wind-up shaft.
Turning the knob clockwise will release the wind-up shaft again.
Wind-up tension control (6), knob;
By turning this knob clockwise an amount of friction is set between the shaft and
the driving sprocket wheel, so this will act as a coupling between motor and wind-
up shaft.
To release the tension, turn the knob counter-clockwise.
Unwind tension control (7), knob;
By turning this knob clockwise an amount of friction is set between the shaft and
the frame, so this will act as a brake.
Tightening the brake will apply more tension to the material on the shaft.
Turning the knob counter-clockwise will release the brake and therefore release
the tension.
