Abstract
A pressure platen for use in an endless abrasive belt surface finishing device which includes a platen assembly arranged to move in a reciprocal pattern relative to the work surface. The assembly includes means for continuously driving the platen along a reciprocal path with platen guide wheels being provided which engage a stationary track for maintaining horizontal orientation of the platen. The surface of the platen is preferably provided with a graphite containing cloth cover. The improved platen assembly enhances the performance of the system through improvements to the quality of the finish, a significant increase in belt life, and also an increase in the lifetime for the graphite impregnated cover.
