ABSTRACT:
A web bending fixture to bend lithographic plates used in web offset printing and production. Precise bends are created by a precision machine tool fixture. The fixture utilizes continuously supported eccentric camming members, one on each end of the fixture, each supported by a plurality of split bearings within which the camming members rotate. After the lithographic plate is precisely aligned with unique registration means and immobilized, the camming members, are moved into position and, rotating within the bearings, form the leading and trailing edges of the plate around precisely positioned and fixed anvils.
