Die cutter blanket locking arrangement

A die cutter blanket for use with a cylindrical anvil having an axially extending channel in the surface thereof comprising:

• a urethane sheet member blanket having first and second ends, the blanket for wrapping about the anvil;
• a plurality of complementary interlocking fingers at said first and second ends for selective interlocking engagement with each other to secure the blanket to the anvil;
• a first projection depending from and integral one piece with the sheet member blanket of the same material as the blanket at at least one of said ends for complementary engagement with said channel, the material forming the projection and blanket having a first given property such that the blanket exhibits excessive surface wear at said first projection in comparison to the rest of the blanket surface during use unless otherwise precluded;
• and
• a molded urethane sheet insert embedded in said blanket at at least one of said ends overlying at least said first projection, the insert having a second given property different than the first given property for substantially precluding said excessive wear.
