The trimmings buffer motor (M37) turns on and moves the trimmings buffer [3] slightly to the left by a
prescribed distance and stops. The trimmings sub buffer disengages from the hook that links it to the book
press plate [4] and returns to its home position, allowing the trimmings to fall into the trimmings buffer .
2nd Cut
This operation cycle for the 2nd cut is the same as 1st cut.
3rd Cut
The sub buffer operation (used for the 1st and 2nd cuts) is not used for the third cut on the fore edge. The
trimmings are allowed to fall directly into the trimmings buffer.
After 3rd Cut
The trimmings buffer motor (M37) turns on and moves the trimmings buffer [1] to the top of the trimmings
box on the right.
The trimmings buffer moves to the right until the trimmings buffer HP sensor: left (S103) goes ON then the
amount of movement to the right is controlled by a rotation flag in the trimmings buffer clock sensor (S101).
First, the trimmings buffer and book press plate [2] stop at the home position with the dump port [3] of the
book press plate over the trimmings box [4]. Next, the trimmings buffer moves over the dump port so the
trimmings [5] can fall into the trimmings box below.
