10.3.1 Pneumatic Tape Cutter and Empty Tape Duct
The pneumatic tape cutter unit is fixed to the frame of the docking unit with 4 screws. It separates plastic,
aluminum and paper tapes up to a maximum pocket depth of 25 mm. The tape clippings fall down the
waste slide, into the waste tape bin of the component trolley.
The empty tape duct is constructed so that it covers the cutting edges of the tape cutter (for safety), so
that it controls movement of the empty component tapes to the cutter, so that the component reject bin
is integrated and so that it can receive the various nozzle changers for the C&P6/12/20 and TwinHead.

10.3.2 Structure and Function of the Pneumatic Tape Cutter
The empty tape duct guides the empty tapes through the opening (3) in the cutter.
The cutter is based on a horizontal frame (1) with a fixed cutting edge and a flexible blade, which is
moved by two short-stroke cylinders (2). At each upwards or downwards movement, the device cuts off
the tape.
The proximity switch (5) signals the position of the short-stroke cylinder piston and therefore the position
of the cutter blade. The proximity switch enables the control electronics (4) to register whether the tape
has been cut. Cutting only takes place during placement. For operational safety reasons, the tape cutter
is integrated into the emergency stop circuit.
The pneumatic tape cutter is fixed on the frame of the docking unit with four screws and this, together
with the empty tape duct is a complete unit.

The tape cutter is activated when the gantry moves to the first placement position. Alternating one of the
cylinders start to front position. Once the first cylinder reaches the front position, the second cylinder is
started. Both signals ’blade in front position’ trigger control unit to withdraw both cylinders at the same
time.
The cutter can be removed in about 15 minutes for service purposes. For detailed information about
dismantling, refer to the service manual.
