The RW500 rewinder is a center-driven rewinder with servo drive and elec-
tric roll lift.
The compressed air is supplied via an external compressed air hose.
The compressed air supply is required to:
• Tension the pneumatic core shaft in the paper roll core.
• Supply the pneumatic dancer.
• Supply the pressure arm.
The main control panel with EMERGENCY STOP palm button is used to
control the:
• Roll lift.
• Rewinder in the machinery (system).
The roll lift is used to load and unload paper rolls.
The rewind direction is counter clockwise in normal operation (viewing di-
rection from operator side).
Reverse operation (rewind direction clockwise) is possible.
The winding speed of the paper roll is controlled by:
• A sensor that records the roll diameter.
• The position of the dancer.
The diameter of the standard core shaft is 70 mm.
As an option, core shafts with larger diameters can also be supplied. This
is recommended when processing thicker papers or cardboard.
The compressed air pistol is used to tension the pneumatic core shaft in
the paper roll core.
The pressure arm with pressure shaft prevents air pillows forming between
the webs.
This improves the winding quality.
The roll end or roll change is set by entering a specific roll diameter in the
touchscreen.
