A polyurethane layer is bonded to a sheet metal liner and secured to an anvil roller channel by depending interlocking male and female locking members at the respective blanket ends. The female locking member comprises a U-shaped channel member formed from the liner. The channel member has an extension formed of doubled over sheet material with an inclined lip for engaging the anvil channel in resilient interference fit in cooperation with a distal channel member side wall. The channel member is filled with the layer material as the layer is formed to form a solid female member and has a lateral side wall from which a locking projection extends for locking engagement with a mating recess in the male member. A wedge projection projects from a face of the male member contiguous with the outer blanket surface. The wedge projection extends from the blanket outer surface an extent smaller than the blanket layer thickness to minimize insertion load on the male member due to interference with the female member. This projection compresses during installation and expands during use to fill a gap that otherwise would form between the blanket end faces.
