Crooked/Warped Squarebounds
Crooked or warped spines of square bound books are a result
of the glue that is used to attach the cover to the book.
A constant bead of glue was very hard to maintain, and very
often an excess dose of glue would be applied to the cover prior to it being
attached to the book. When the cover was stuck to the body pages, the spine is
ran across a roller to flatten it and give it the square shape, then another
pair of rollers flattens it out on the front and back covers. If there was
excess glue, it would cause the various warping defects. Square bound books are
made the same as stitched books with one exception; the body pages are grouped
into eight page “sections” and stacked on top of each other. The stack is
stitched (stapled) front to back to hold them together, instead of through the
center of the book as on a traditional comic. Finally, as touched on before, a
bead of glue is applied to the spine and the cover is wrapped around the body
pages.
This defect of a warped spine is very common on such books
as Giant-Size X-men #1 or any other square bound book.
