Floor cleaning grinding or polishing machine - has motor driven brushes or stones kept in same plane as support roller

摘要

The floor cleaning polishing or grinding machine has a baseplate (23) on which a motor is mounted. Underneath is a flange which carries grinding (polishing) stones or brushes which are rotated by the motor. A roller (17), with its spindle parallel to the surface (19) which is to be worked, is mounted on the baseplate or its housing (11). The place (20) where the roller touches the work surface is in the same plane (21) in which the working surfaces of the brushes etc. lie. The height of the roller can be adjusted. Two short rollers can be used, instead of one long roller. The height is adjusted by a handwheel (18) alongside the motor (15).
