Abstract:
1. A method of manufacturing a rubber sheet containing short fibers, the method comprising the steps of: mixing short fibers in a flowable rubber matrix; forming the flowable rubber matrix with the fibers therein into a cylindrical shape with a circumferential extent using a die from which the flowable rubber matrix departs at a first location in the cylindrical shape; separating a portion of the circumferential extent of the cylindrical shape with the flowable rubber matrix with fibers therein in the cylindrical shape; and forming the cylindrical shape with the portion separated into a sheet form, wherein the step of separating a portion of the circumferential extent comprises separating from 5–25% of the circumferential extent by cutting the cylindrical shape adjacent to the first location.
