BACKGROUND
The appellants’ invention relates to a quad roll decurler
wherein the degree of curl can be adjusted (specification, pages
1 and 6).
Claim 1 is representative of the invention, and is
reproduced as follows:
1. A quad-roll curl control apparatus comprising:
first, second, third, and fourth rolls configured to form
first and second nips;
the first nip comprising the first and third rolls;
the second nip comprising the second and fourth rolls;
respective bearings supporting ends of the first and second
rolls;
the third and fourth rolls each having a substantially
uncompressible surface;
the first and second rolls each having a compressible
surface into which the third and fourth rolls selectively
penetrate, respectively;
a curl adjuster connected to the first and second nips to
control the selective penetration of the first and second roll
compressible surfaces by the third and fourth roll substantially
uncompressible surfaces; and
a gate member in communication with the first and second
nips, the gate member sending sheets to one of the first and
second nips for application of respective types of curl.
