stuffing
1. The operation of inserting layers of chipboard
into a book having excessive sewing swell before
nipping, so as to prevent the book from starting.
Also called "packing." See: START . 2. The
process of incorporating grease into a tanned
hide, either by hand or by drumming, so as to
improve its quality or to impart special
properties. DUBBIN
is frequently employed in this process, although
other materials are also used. The mixture spreads
over the damp fibers, and penetrates into them as
the leather dries. The oil enters the hide easily,
while the harder fat remains on the surface or in
the surface layers. Stuffing is generally used on
heavy hides in lieu of FATLIQUORING . (305 , 339 , 363 )
