Abstract
A durable belt device includes an outer layer made out of a rubber based material and an inner layer that includes at least one reinforcing ply of tear-resistant scrim fabric located between opposed surfaces thereof and a multiplicity of needle fibers that run substantially transversely and perpendicularly through the reinforcing ply and protrude out from at least one surface of the inner layer. A bonding agent forms an intermediate layer that secures the outer layer to the one surface of the inner layer such that the fibers at least partially extend therein.
Claims15
A durable belt device, said belt device comprising:
- a first layer defining generally opposed first and second surfaces, said first layer including a rubber based material;
- a second layer defining generally opposed first and second surfaces, said second layer including at least one reinforcing ply of tear-resistant scrim fabric extending between said first and second surfaces thereof in a direction substantially parallel thereto, said second layer including a multiplicity of needle fibers extending through said reinforcing ply and between said first and second surfaces of said second layer in a direction substantially perpendicular thereto, said fibers protruding out from at least said first surface of said second layer;
- and
- a bonding agent forming an intermediate layer securing said first surface of said first layer to said first surface of said second layer, whereby said fibers at least partially extend into said intermediate layer.
