Die cutter blanket and bearing and method of arranging the blanket and bearing on an anvil

摘要

A circular cylindrical bearing section for a die cutter blanket comprises two segments pivoted relative to each other at one interface therebetween and resiliently urged radially apart by spring plungers at a second interface therebetween. A blanket section is wrapped about the two segments which are resiliently urged against the overlying blanket section secured to the bearing section by a conventional channel in the bearing and mating male-female interlocking members on the blanket. An array of bearing-blanket sections on an anvil roll are axially coupled by annularly spaced mating pins and notches at opposite axially facing edges of the bearing sections. The array of bearing-blanket sections are selectively slid as a unit along the anvil roll to rapidly relocate the blanket sections to minimize local blanket wear. The interlock members of each blanket section may be misaligned axially with the respect to the interlock members of the adjacent blanket sections.
