continuous trimmer
A trimming machine which does not have to be
stopped and started for each cut, as is the usual
case with the typical guillotine cutter. It has a
revolving cutting bed equipped with four faces,
each of which has its own clamp. When one clamp is
filled with books, it closes and the bed makes a
quarter revolution carrying the books under the
fore-edge knife. While the fore edges are being
trimmed, the operator fills the next clamp, the
bed makes another quarter turn, and the heads and
tails of the books in clamp one are trimmed at the
same time the fore edges of the books in clamp two
are being trimmed. Another quarter turn brings the
books in clamp one over a conveyor where they are
released. (339 )
