building-in machine
A machine used to BUILD IN the text
block of a book into its case or covers.
Building-in machines substitute heat and great
pressure for the element of time required to set
and cure the adhesive and form the joints. For
intermittent or relatively small production, a
single-clamp machine, such as the type often found
in library binderies, is often adequate. It can
build in books up to 12 by 14 by 4 inches in size,
and can process up to five books per minute,
depending upon the skill of the operator and the
CLAMP DWELL
setting of the machine. In general, the longer the
dwell time, the more solid the binding, which is
essentially the reason why a book built in by this
type of machine is not as solid as one left in a
press for a longer period of time. In edition
binding, multiple-clamp machines are usually used,
and can process up to 36 books per minute. In
edition machines, books may be manually inserted,
or fed in automatically after CASING-IN . See also:
