STRIPPING CAPACITY
A stripping load is a force which occurs on the UP
stroke of the ram. The direction of this type of load
is down on the ram and up on the bed (the reverse
of forming and punching loads). Figure 4-5 shows
the maximum stripping load available at the center
of the machine.

ECCENTRIC LOAD CAPACITY
(FRONT-TO-BACK)
Occasionally special forming or punching set ups
are made which do not have their load centers
located on the bed and ram centerlines. When this
condition exists, care must be taken not to exceed
the maximum eccentric (front-to-back) load capac-
ity of the machine. See Figure 4-6.
