ABSTRACT:
A surface finishing member having an extended working surface adapted for movement repetitively across the surface of an object to be finished, and a method of its manufacture. The member has a body formed of a reinforcement layer lying generally parallel to and spaced substantially below the working surface, the layer being substantially inextensible in a direction of movement, a relatively thick working layer having throughout a large multiplicity of wear-resistant fibers in a random, needled mass, component fibers of the layer being needled through the reinforcement layer, and an elastomeric material impregnated through the working layer and the reinforcement layer. The member may also include pre-applied particles of finishing compound disposed at and adjacent to the working surface. When the finishing member is new, the thickness of the working layer between the working surface and the reinforcement layer is the major thickness of the member. During operation, and as gradual wear of the working layer occurs, the impregnated mass of needled fibers at the working surface continually defines surface interstices in which particles of abrasive compound can lodge and be carried with resilient support across the surface to be finished. In the preferred embodiment the member is in the form of a belt.
