ABSTRACT:
A resilient disc shaped wheel and supported abrasive belt for grinding glass. A central bore in the wheel provides for mounting to a rotating drive shaft driven by a motor. Circumferentially spaced radially extending slits are disposed incrementally around the entire circumference of the wheel, defining flexible teeth therebetween. The slits are cut only a portion of the way through the wheel leaving a continuous membrane of resilient material tending to hold the teeth in position upon rotation. An abrasive belt is positioned around the outer perimeter of the wheel, and held in place by the centrifugal forces imparted to the teeth.
