gluing up ( glue up, glue off, gluing off )
1. The process of applying glue, or other
adhesive, to the spine of a book following sewing.
In edition binding, gluing up is a machine
operation, but in library and hand binding it is
generally done by hand. Usually, one of the
polyvinyl adhesives, e.g., polyvinyl acetate, or a
hot, flexible animal glue, or even a hot-melt
adhesive is used. The major purpose of gluing up
is to put the spine of the book in the proper
flexible condition for the molding operations of
rounding and backing. As these two processes were
not introduced into bookbinding until the early
part of the 16th century, gluing up was not done
before that time.
There are advantages in using a relatively slow
drying adhesive in gluing up, as such an adhesive
will remain tacky while the spine is shaped and
the shoulders are set.
2. The operation of gluing the cloth or paper used
for making covers or cases. (102 , 236 , 256 , 335 )
