edge gilding machine
A machine, used mainly in edition binding, for
gilding the edges of books. The books are placed
in the machine and the edges are prepared for
gilding in the usual manner. A sheet of gold foil
is placed over the edges, and heat and pressure
are applied by two heated silicone rubber rollers.
The first roller, which is used in conjunction
with a sheet of fiberglass, smooths the foil over
the edges and insulates the foil from heat until
it is under pressure. The second roller then
presses directly onto the foil and seals it to the
edges. Large numbers of books are edge gilded in
this manner, particularly in the Bible publishing
business. (229 , 264 )
