nipping press
A small press consisting essentially of a fixed,
horizontal iron base plate, and an upper, movable
platen that is raised and lowered by means of a
relatively long, vertical screw. The nipping press
is used to apply quick and uniform pressure in a
variety of bookbinding operations. While the
nipping press does not have the available DAYLIGHT or the
pressing power of the STANDING PRESS , it
is relatively easy to open and close which makes
it very useful for a quick pressing operations.
The true nipping press does not release its
pressure until released by the turning of the
screw; however, substitute "nipping presses,"
which are really "letter-presses" or "copying
presses," once used in business offices for
"copying" letters, are limited in their ability to
apply pressure because they have a tendency to
ease the pressure when the handle is released. (203 , 335 )
