Blanket clamping apparatus

摘要

A blanket clamping and tensioning apparatus for use in a blanket cylinder in a rotary printing press is disclosed. An axial groove at the periphery of the blanket cylinder carries a pair of spaced inserts which define an interior chamber. A radially movable clamping bar assembly is carried within the chamber and contacts camming surfaces on the inserts. The ends of the blanket are inserted in the space between the inserts and the clamping bar assembly is moved radially inwardly thereby camming clamping means toward each other to grip the blanket. Four embodiments are disclosed in which there are shown different gripping portions of the clamping bar assemblies.
