5.1.5 Cutting Waste Tape
After parts have been picked out of the tape, the empty “waste”
tape is cut off. Waste tape that has been cut is collected by a
vacuum at the back of the machine.
The waste tape cutting operation is driven by a cam mechanism.
The cam drives a lever, which drives a rod, which drives a lever,
which drives the cutter.
The stroke of the rod is a fixed value determined by the curve of the
cam.

Follow the procedure below to adjust the stroke of the waste tape
cutter claw.
(1) Attach the cam handle on the handle shaft. Turn the handle
until the cam angle indicator reads 245°.
(2) With the cam angle set to 245°, adjust the rod so that the
moving cutter touches the fixed cutter. At this time, the gap
between the the tip of the moving cutter and the underside of
the fixed cutter should be more than 0.5 mm.

(Cam Angle 245°)
(3) Return the cam angle to 0°. Confirm that the gap between the
moving cutter and the fixed cutter is more than 7 mm, and that
the moving cutter lever does not contact the plate.
