  • Patent number: 5229183
    Abstract: A method of manufacturing a protective member for a drum from a supply of used tires. A first used tire is obtained from a source and the sidewalls are removed to define a first cylindrical tread section. The first cylindrical tread section is severed to form a first strip. A second tire is obtained from the source and the sidewall removed to define a second cylindrical tread section. The second cylindrical tread section is severed to form a second strip. The first and second strips are thereafter joined together to form a unitary structure. A plurality of substantially rectangular members are cut from the sidewalls of either the first or second used tire. The plurality of rectangular members are attached to the unitary structure to form cleats. The cleats are fixed to a floor to position said unitary structure around the drum and hold the drum in a stationary position.
