ABSTRACT:
A replaceable cover for the cylindrical anvil of a rotary die cutter includes a blanket body of elastically deformable material, a sheet metal liner for the blanket body, and a latch assembly for securing the ends of the cover together in a lengthwise slot in the face of the anvil roll. This cover is particularly designed for use with a prior art anvil roll wherein the slot in the face of the roll has opposed parallel sides which extend at right angles to the bottom of the slot, and each of which is provided with a groove along its lower edge that forms an extension of the slot bottom. The latch assembly includes a channel member having one side secured to one end of the blanket liner so that the open side of the channel faces the other end of the blanket body for interlocking cooperation with a latch member integrally formed on the other end of the blanket body. The radially inner side of this channel member is sufficiently wider than the slot in the anvil roll so that its edge extends into one of the grooves in the corners of the slot in the anvil roll in the assembled condition of the latch assembly.
