edging
1. The beveling of an edge, usually of a leather
covering, but also paper, vellum, etc., by means
of an EDGING KNIFE
. The purpose of "edging" a leather cover is to
prevent the leather turn-in from bulging,
especially at the head and tail of the spine. When
applied to paper, the term generally refers to the
process of cutting or beveling two pieces of paper
so that there is no high or low spot where they
are joined. In craft bookbinding today, edging of
paper is more or less obsolete, having been
superceded by the use of long-fibered Japanese
copying paper. 2. See: EDGE ROLLED .
