Abstract:
A floor polishing or grinding pad assembly is provided. In one aspect, a polishing or grinding pad assembly employs a fibrous pad, a reinforcement layer or ring, and multiple floor-contacting disks. In another aspect, the reinforcement layer includes a central hole through which the fibrous pad is accessible and the fibrous pad at the hole has a linear dimension (x) greater than a linear dimension (y) of one side of the adjacent reinforcement layer. In yet another aspect, at least one of the floor-contacting disks has an angle (α) offset from that of a base surface of the disk, the fibrous pad and/or the reinforcement layer. A further aspect employs a smaller set of disks alternating between and/or offset from a larger set of the disks. In another aspect, the reinforcement layer includes a wavy or undulating internal edge shape.

Claim (Index 29):
A method of using a pad assembly, the method comprising:\n (a) attaching an upper side of the pad assembly to a powered machine; (b) contacting abrasive tools of the pad assembly and a flexible pad of the pad assembly against a floor, with a reinforcement layer being located between the pad and the tools; (c) exposing a central area of the pad through a hole of the reinforcement layer such that a linear dimension of the central area within the hole is greater than a linear dimension of one side of the reinforcement layer between the hole and a periphery thereof, such that the central area of the pad contacts the floor; (d) rotating the pad assembly by the powered machine; and (e) polishing or grinding the floor with a floor-contacting nominal surface of at least some of the tools, which is angularly offset by at least two degrees relative to a bottom surface of the pad.
