ABSTRACT:
A pad assembly for a vacuum rotary sander has a flexible pad body secured to a rigid head that is connectable to a vacuum housing and a pad rotating means. A plurality of apertures in the head communicate with other apertures in the lower surface of the pad by internal channels which are angled toward the direction of rotation of the pad. The apertures in the lower portion of the pad coincide with apertures in an abrasive disc removably secured to the assembly and may be elongated in the direction opposite to that of rotation so as to allow some slippage of the abrasive disc relative to the pad assembly. There is also disclosed a device for quickly positioning and loading an abrasive disc onto the pad assembly.
