comb binding
A form of MECHANICAL
BINDING consisting of a plastic strip on the
spine from which curved prongs extend. They are
inserted into holes punched into the leaves to be
held. The name derives from the resulting "comb"
appearance of the binding. This type of mechanical
binding provides a more-or-less solid spine on
which the title of the publication may be printed.
Its disadvantages, however. are many: leaves may
be removed quite easily by unauthorized persons,
and groups of leaves often slip from the grasp of
the flexible prongs. In addition, leaves tend to
tear from the binding because the large, usually
rectangular, slots leave relatively little paper
along the line of the punched holes. (316 )
