ABSTRACT:
A driver assembly for the pad of a high speed floor burnishing machine includes a flexible backing plate having a peripheral retaining skirt which centers the pad on the driver assembly and also prevents the edges of the pad from growing or expanding to a larger circumference during high speed rotary burnishing action. The backing plate adds stiffness to the pad when rotating at high speed, and it promotes uniform contact of the pad with the floor at the outer radial extremities of the pad where the velocity is greatest and the polishing is most effective. In the illustrated embodiment, the pad and driver assembly are surrounded by a shroud which is continuously evacuated by radial air flow generated by the motion of the driver assembly which includes a finned hub. The air flow carries debris generated by the burnisher to a collection bag or filter without leaving the machine.
