Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abrasive sheet including a plurality of protrusions

An abrasive article is provided that has a backing having opposed first and second major surfaces, an abrasive layer disposed on the first major surface, and a plurality of protrusions extending outwardly from the second major surface. The protrusions comprise a polymer having a Shore A hardness ranging from 5 to 90. These articles provide an alternative sanding solution enabling abrasive articles lacking an attachment layer to be handled effectively and efficiently, providing for a technically superior abrasive sheet on the marketplace that does not use or require an attachment layer.

Abrasive articles, assemblies, and methods with gripping material

A sheet of coarse sandpaper includes a backing layer having opposed first and second major surfaces, an adhesive make coat on the second major surface, coarse abrasive particles at least partially embedded in the make coat, thereby defining a coarse abrasive surface, and an exposed non-slip coating layer on the first major surface. Methods of making and using such coarse sandpaper are also provided.

Sanding tool

A sheet of sandpaper includes a backing layer having opposed first and second major sides, an adhesive make coat on the second major side, abrasive particles at least partially embedded in the make coat, thereby defining an abrasive surface, and an exposed laminated non-slip layer on the first major side. Methods of making and using such sandpaper are also provided.

Sandpaper with laminated non-slip layer

A sheet of sandpaper includes a backing layer having opposed first and second major surfaces, an adhesive make coat on the first major surface, abrasive particles at least partially embedded in the make coat, thereby defining an abrasive surface, and a non-slip coating layer on the second major surface. Methods of making and using such sandpaper are also provided.

Sandpaper with non-slip coating layer

Method of hand sanding a work surface

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.

Laminated flexible resilient abrasive article

A sheet of sandpaper includes a backing layer having opposed first and second major sides, an adhesive make coat on the second major side, abrasive particles at least partially embedded in the make coat, thereby defining an abrasive surface, and an exposed fibrous non-slip layer on the first major side. Methods of making and using such sandpaper are also provided.

The disclosure is directed to conversion assemblages adapted for use in converting a surface modifying apparatus, such as a pole sander, whereby the conversion assemblage includes a generally rigid body assembly including first and second major surfaces opposing each other, the first major surface is adapted for receiving the supporting member, and the second major surface is attachable to a surface modifying member.

Conversion assemblage adaptable for use in combination with a surface modifying apparatus and method thereof

Disclosed are surface modifying apparatus, such as non-motorized and motorized sanding tools, with an illumination system providing an intensity and incidence angle on the working surface that facilitates visual inspection of defects and blemishes on the surface being modified in a safe, low cost, and convenient manner.

Surface modifying apparatus having illumination system and method thereof

A resilient hand-held abrasive article includes a flexible conformable backing layer having opposed first and second major surfaces, a flexible reinforcing layer affixed to at least one of the backing layer first and second major surfaces, and abrasive particles arranged on the reinforcing layer, thereby defining an abrasive surface. The backing layer comprises a multiplicity of separated resilient bodies connected to each other in a generally planar array in a pattern that provides open spaces between adjacent connected bodies.

Resilient abrasive article

A resilient hand-held abrasive article suitable, for example, for woodworking, includes a plurality of separated raised abrasive surfaces to allow the article to more effectively conform to a contoured surface. A method of making such an abrasive article is also disclosed.
