Abstract

Abstract A pad for treating surfaces such as floors or the like which includes a plate member of rigid material which is wrapped with a continuous ribbon of stainless steel which is relatively thin and narrow, the wraps extending in a circular manner successively over and under the plate member, successively and alternately, in random directions to build up a soft, cushiony mass of the stainless steel strip to a thickness such that the wound ribbon completely covers the plate member in a plurality of layers with the plate member disposed centrally within the mass to form a pad suitable for attachment to a floor-treating machine. This invention relates to an apparatus for treating surfaces and more particularly to a pad of stainless steel arranged to be mounted on a machine for treating surfaces such as floors.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 131 words
A pad adapted to be attached to a rotary buffing machine or the like for treating surfaces such as floors comprising, in combination, a substantially planar, disc-shaped rigid core member of stainless steel wire mesh having a top surface and a bottom surface and a marginal edge, a continuous narrow thin ribbon of stainless steel having a width between approximately 1/16 to 1/8 inches and of helical configuration to provide continuous coils extending throughout its length, said ribbon being wound successively and alternately over said core member top and bottom surfaces in random directions diametrically in a plurality of wraps extending around said marginal edge, portions of said wound ribbon being randomly distributed in overlying relationship to form a circular sponge-like mass with said core member disposed centrally within said mass.
