USP 13 Universal Speed Punch
Operating Instructions
The Universal Speed Punch from
GBC Automated Finishing Division
is specially designed to punch
various weight paper sheets and
cover stock. The machine has a
variable speed control which can be
adjusted from 70-110 cycles per
minute.
The thickness of individual layers
being punched is adjustable, but
should not exceed a maximum of
.080” per lift. Depending on the
quality and weight of the material
being processed, it may be necessary
to adjust the lift to less than maximum.
.070” is a good operating lift to avoid
excessive wear on the punch pins and
to maintain a quality hole.
With proper maintenance the
Universal Speed Punch will provide
troublefree, continuous operation for
many years.
Important: Only a sharp, well-
lubricated and properly installed die
set will have a long life and give
good quality punching. Clean punching
without paper welding yields more
efficient binding. Punching dies should
be sharpened every 100 hours of
operation or when the punched holes
begin to get ragged. This, too, will
depend on the type of stock being
punched, i.e. hard finish, coated, etc.
REPLENISH THE SUPPLY HOPPER
CONTINUOUSLY TO OBTAIN
MAXIMUM PRODUCTION.
