<p>A circular cylindrical bearing section (6) for a die cutter blanket comprises two segments (38, 40) pivoted relative to each other at one interface (34) therebetween and resiliently urged radially apart by spring plungers (54) at a second interface (36) therebetween. A blanket section (26) is wrapped about the two segments (38, 40) which are resiliently urged against the overyling blanket section (26) secured to the bearing section by a conventional channel (59) in the bearing and mating male-female interlocking members (28, 30) on the blanket. An array of bearing-blanket sections (8-10) on an anvil roll (4) are axially coupled by annularly spaced mating pins (74) and notches (80) at opposite axially facing edges of the bearing sections. The array of bearing-blanket sections (8-10) are selectively slid as a unit along the anvil roll (4) to rapidly relocate the blanket sections (26) to minimize local blanket wear. The interlock members (28, 30) of each blanket section (26) may be misaligned axially with the respect to the interlock members of the adjacent blanket sections.</p> |
