ABSTRACT:
A first layer of urethane sheet material is molded with a plurality of interlocking male and female fingers at opposing blanket ends and which fingers form a projection for insertion into an anvil channel. The fingers are arrayed in a plane beneath the plane of the first layer. The abutting ends of the blanket above the fingers form a seam of different configuration than the fingers, e.g., linear, to minimize formation of flat spots on the work surface. A fabric is bonded to the underside of the sheet material in one embodiment or a second layer of urethane is molded to blanket underside to form a major portion of the fingers and the projection in a second embodiment. The second layer has a relative durometer that is harder than the first layer, and a shrinkage smaller than that of the first layer to minimize the formation of edge curl.
