Plockmatic PowerSquare™ 224 - Service Training Workbook
Trim blade marking
The trim process uses a double-edge blade to cut thick
books. This can leave a small mark in the centre of the
trimmed edge. The visibility of this mark will depend on
the paper quality and characteristics.
Stitch form
Legs should lie flat so they cannot cause injury
Legs should not re-penetrate the spine
If this is not the case, correct job settings or make
service correction.
Spine forming
The quality of the SquareBack spine is subjective and is
operator adjustable. Its purpose is to produce a book
with a superior appearance to a non-formed spine. The
appearance of the spine will vary according to material
and machine set-up.
Spine forming should not cut the paper nor cause
excessive wrinkling. A witness from clamp, spine
forming and fold blade is visible. It should not encroach
into the book beyond the clamp line.
Production may vary according to operating conditions. In line with a policy of
continual product improvement, the manufacturer reserves the right to alter the
materials or specification of this product at any time without notice.
