Trim
The book passes between two facing sets of conveyors in the trimmer infeed. These
conveyors move the book to the trim stop.
The distance of the trim stop from the trimmer blade is calculated by the PSQ160
according to the size of the job. The PSQ160 applies an amount of trim according to
the size of the paper. The operator can change the amount of trim from the touch
screen if necessary.
The trim clamp and trimmer blade move forwards in one action to hold and trim the
book. The trim clamp and trimmer blade then return to their start position.
Trimmings are pushed into the trim bin by flexible fingers on one of the trimmer
infeed conveyor shafts.
The drive for the trimmer blade and the trim clamp is transferred from the main
electric motor by a chain and clutch system. Rotary movement is changed to linear
movement with a crank mechanism.
