Abstract

A pad for a rotary-type floor cleaning and/or polishing machine which comprises a generally disc-like member of hair or fiber mat, etc., which has a perimetral (i.e., circumferential) edge with a series of recesses extending generally inwardly and away from the nominal outer circumference of the disc-like member, toward the center part of the latter, to form a plurality of sequentially arranged, outwardly projecting portions between such recesses which are disposed adjacent one another around the circumference of the disc-like member. In various possible embodiments, these outwardly projecting portions define an undulating or scalloped outer periphery, and such portions are preferably of rounded configuration, formed by arcuate or at least partially circular edges which also define the aforementioned recesses. Further, in preferred embodiments, such projecting portions are disposed directly and closely adjacent one another around the entire outer periphery or perimeter of the disc-like pad.

Claims

1. A pad for a rotary-type floor cleaning and/or polishing machine, comprising:

a fibrous disk-shaped member having a plurality of arcuate projections extending about the outer perimetral edge thereof, each of the projections being of the same size and shape and being defined by a convex outer surface and further wherein the convex surfaces of each projection meets an adjacent projection such that they intersect at a point, the projections further defining a series of inwardly directed recesses therebetween; and

wherein said recesses extend a distance in a radial direction corresponding to about 10% of the nominal radius defining the outermost circumference of the disk-shaped member.
