Title: Machine removes adhered floor coverings, e.g. carpet or plastic flooring
Inventor: FITTERER CHRISTIAN
IPC: E04G23/00
Filed: 1998-03-30
Abstract: This unusual machine prepares floors for new coverings, by completely removing the adhering, old floor covering. This may comprise sheets or tiles of polyvinyl chloride, linoleum, carpet or carpet tiles. Its novel form includes a casing with winding reel for a rope. Electric motor drive and gearing are included. The reel winds the rope, which overlaps neatly, without fouling at the sides. The rope passes over a roller at the same height as the lower edge of the reel. So that the rope may be deployed in all directions, there are also rollers at the corners of the casing. To prevent the tensions arising from causing eccentricity, the machine has sharp wedge supports biting into the floor, in conjunction with a vertical jack extended up, and pressing against the ceiling. Should support against the ceiling be infeasible, the machine is fixed by its corners to the floor.
