ABSTRACT:
A driver assembly for the burnishing pad of a high speed floor burnishing machine includes a rotatably driven hub having spaced-apart recesses in its outer surface. The hub is fixed to a flexible backing plate having inner and outer depending cylindrical retaining flanges defining a channel in which the burnishing pad is received for attachment to the backing plate by a gripper pad. The inner edge of the burnishing pad is clamped against the gripper pad by an inner clamping cup which is received within the inner retaining flange in an interference fit therewith. The driver assembly is supported on a center caster, the wheel of which is disposed in the clamping cup. The burnishing pad and driver assembly are surrounded by a vacuum shroud which is continuously evacuated by radial air flow generated by the motion of the driver assembly.
