摘要： 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 greater than a linear dimension of one side of the adjacent reinforcement layer. In yet another aspect, at least one of the floor-contacting disks has an angle 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.

摘要： A polishing or grinding pad with a multilayer reinforcement is provided. In one aspect, a floor polishing or grinding pad assembly employs a flexible pad, at least two reinforcement layers or rings with different characteristics, and multiple floor-contacting tools such as abrasive disks. In another aspect, a workpiece polishing or grinding pad assembly includes a flexible and rotatable pad, a polymeric reinforcement layer coupled to the pad and a metallic reinforcement layer to which are coupled abrasive tools. In yet another aspect, a floor-facing reinforcement is more flexible than a pad-facing reinforcement which is more rigid.
