Improvements in high speed floor burnishing machines.

摘要

A pad driver assembly (40) for a high speed floor burnishing machine (10) includes a flexible or semi-rigid backing member (45) with a pad (53) beneath it and gripping projections (54) for holding the pad (53) in place. The backing member (45) is provided with apertures (50) so that when the pad assembly (40) is driven at high rotational velocities beneath a shroud (20), air is drawn in through the apertures (50) and forced radially outward in the pad (53), increasing the gripping action between the gripping projections (54) and the pad (53), and also increasing the downward atmospheric pressure on the peripheral portion of the pad to promote increased polishing effectiveness.
