5-5
5. Book Quality
5.10 Books Not Square
Description
Books appear as though they are not cut
square.
Possible Causes
Books are allowed to cool with a twisted
binding as shown in Figure 5-9. When
a book is straightened after trimming, it
looks similar to the book shown in Fig-
ure 5-10. This is the most common
cause of out of square.
Cover overhangs the book. The over-
hang reduces the reliability of the squar-
ing process within the trimmer.
Glue was applied past the binding, leav-
ing a knob-like protrusion. The protru-
sion interfered with the trimmer's regis-
tration and squaring process.
Normal wear has forced the cutting or
registration mechanisms out of square.
Solutions
Carefully handle books that have soft
bindings. Keep twist out of the binding
while glue is setting.
Cut the cover to match the size of the
untrimmed book and/or reduce jogging
pressure (Section 3.6.6 Hydraulic/Air).
Adjust the binder such that glue will not
be applied past the end of the binding.
If normal wear has forced the cutting or
registration mechanisms out of square,
refer the problem to an authorized ser-
vice technician.
