Problems solved by technology

Conventional sandpaper generally exhibits good initial stock removal (i.e., cutting) characteristics, but produces relatively deep scratch marks for a given mineral glue, and often has an undesirably short life
Additionally, the thin, flat, smooth nature of traditional sandpaper makes the article difficult to grip, control, and manipulate, and does not make the sandpaper well suited for sanding curved, contoured or textured surfaces

Embodiment Construction

[0026] Referring now to the drawings, in which like reference numerals indicate like or corresponding parts throughout the several views, Figure 1-3 A pliable resilient abrasive article 10 comprising an abrasive sheet 12 and a backing sheet 14 is shown. The abrasive sheet 12 includes an abrasive support layer 16 attached to a backing sheet 14, an integral coating 18 ( image 3 ) on the abrasive support layer 16, and a plurality of abrasive particles 20 at least partially embedded in the integral coating 18. The abrasive support layer 16, integral coating 18 and abrasive grains 20 included in the abrasive sheet 12, and the backing sheet 14 are described in detail below.

[0027] Backing sheet 14

[0028] The backing sheet 14 is formed from a durable elastic conformable material. The backing sheet 14 provides a comfortable gripping surface for the user and also provides a degree of conformability to the abrasive article whereby the abrasive article 10 can more effectively ...

Abstract

A sheet-like abrasive article includes a resilient backing sheet having opposed major surfaces and a continuous abrasive sheet affixed to the backing sheet. The abrasive sheet includes an abrasive support layer with abrasive particles arranged thereon, thereby defining an abrasive surface. A sanding tool assembly including such a sheet-like abrasive article is also disclosed.

Description

Background technique [0001] The present invention relates generally to sheet-like abrasive articles for abrasive work surfaces, and more particularly, to flexible, resilient sheet-like abrasive articles, and to sanding tool assemblies including such abrasive articles. [0002] Sheet-form abrasive articles are commonly used in a variety of sanding operations including manual sanding of wooden surfaces. During manual sanding, the user may hold the abrasive article directly in the hand and move the abrasive article across the work surface. Of course, manual sanding is a more laborious task. [0003] To facilitate manual sanding, the sheet-like abrasive article can be placed on the sanding board. The sanding plate is firmly attached to the abrasive article, and the user can grasp it at any time, making manual sanding faster and easier. One commercially available sanding board is the 3M Grinding Board, available from 3M Company in St. Paul, Minnesota. TM Rubber matte board (3M ...
