trimmed in the square
The most common method of cutting a sewn book, in
which the edges are trimmed before the book is
rounded. In cutting the head and tail, the spine
of the book is placed in the cutter against the
guide so as to avoid breaking pieces out of the
folds. If there is much sewing swell in the spine,
it may be necessary to build under the clamp of
the cutter to compensate for the swell, otherwise
the book may slip under the clamp because of the
shearing action of the guillotine knife. Cf: TRIMMED IN THE ROUND
