Trimming
Booklet maker sends a start signal. The transport motor (TM-M1) starts and trans-
ports the booklet into the machine. The infeed sensor (TM-Q13) is activated by the
booklet. The booklet passes and deactivates the infeed sensor (TM-Q13). When
the booklet hits the stop gate, the transport motor (TM-M1) stops. The timing is
controlled by transport motor sensor (TM-Q4) and set by the paper size.
Trim knife motor (TM-M2) starts moving the knife down. After a while when the
knife is about to cut the sheets, transport motor (TM-M1) is triggered by knife posi-
tion sensor (TM-Q5) to reverse and helps knife motor (TM-M2) during the cutting
stroke. About the time when the knife has cut through the sheets, the stop gate
motor (TM-M3) moves the stop gate down and the transport motor (TM-M1) re-
verses again to transport the set out of the machine. The knife motor completes its
cycle and stops at the trim knife home position sensor (TM-Q5).
The stacker motor (ST-M1 - not shown in picture) starts when the outfeed sensor
(TM-Q6) activates and runs for a short while to separate the booklets on the stack-
er belt. When outfeed sensor (TM-Q6) activates, stop gate motor (TM-M3) moves
the stop gate to up position and is stopped when the stop gate home position sen-
sor (TM-Q7) activates.
