Plockmatic PowerSquare™ 224 - Service Training Workbook
8.5 Shuttle - Book Transport
The set is collected by the shuttle and moved to the 1st stitch position. A cam
mechanism tightens the shuttle pick-up fingers on the set when the shuttle
moves towards the 1st stitch position. The increased hold makes sure the
pages remain in alignment when the set is stitched. The rear or large shuttle
pick-up fingers incorporate rollers to prevent toner deposition that could mark
the covers of the books.
The set is stitched, then moved by the shuttle to the next stitch position. This
process is repeated as necessary to a maximum of 6 stitches. When set to
AUTO, the PSQ automatically calculates the stitch positions. The user can
change the stitch pitch within certain limits. This function can be used to give a
clearance between the stitches and the print on the spine of the book.
The set is moved to the folding area when the set is stitched. When the shuttle
moves to the folding area, the pick-up fingers loosen on the book.
The shuttle is driven by a 230V AC electric motor, Shuttle Servo Motor, through
a linear transmission.
