A laterally-stretched netting comprising a patterned abrasive layer on a first major surface thereof, and methods of making.

A sanding cloth comprising a substrate sheet of flexible and pliable material having a first side and a second side. An amount of first adhesive is applied to the first side of the sheet. A first grit material is applied to the first adhesive wherein the sheet is flexible and easily pliable and conformable to tight fine spaces that are sanded when preparing trim moldings, furniture refinishing and similar finish applications. Adhesive and grit can be applied to one or both sides of the cloth.

Provided are abrasive articles, and related methods, that include a flexible abrasive layer having opposed first and second major surfaces, a foam backing bonded to the second major surface, the foam backing being resiliently compressible, and a plurality of slits disposed on the first major surface and penetrating through the flexible abrasive layer and at least partially through the foam backing. In further disclosed embodiments, the abrasive article includes, a flexible abrasive layer having opposed first and second major surfaces, a structured member extending across the second major surface of the flexible abrasive layer, where the structured member and the flexible abrasive layer have respective three-dimensional patterns of discrete, isolated wells that correspond to each other, and a foam backing extending across a major surface of the structured member opposite the flexible abrasive layer, the foam backing being resiliently compressible.

A lapping material having a knitted fabric constituted by warp knitting or weft knitting, and a resin with which the knitted fabric is impregnated.

The invention relates to obtaining an abrasive product comprising a backing layer and an abrasive layer, wherein the backing layer comprises propylene homopolymer or copolymer.

The invention relates to obtaining an abrasive product comprising a surface with multiple abrasive zones supported by a backing layer. The abrasive zone are surrounded by interconnected channel portions comprising first channel portions with a first transverse dimension td1 and second channel portions with a second transverse dimension td2 larger than the first transverse dimension td1.

A flexible antistatic abrasive with a combined support consisting of a plastic film, on which binder resins are applied, consisting of a maker coat, on which the abrasive adheres, fixed by a size coat and if necessary coated with a third binder, in which the plastic support film is laminated with at least one reinforcement substratum or base support and in which all the components of the combined support are treated with materials designed to provide the support with antistatic properties. Other aspects are disclosed and claimed.

The invention relates to a vulcanized fiber grinding tool (1) comprising two vulcanized fiber grinding disks (2, 3) which are adhered to each other over the entire surface by means of an adhesive layer (4) arranged between the vulcanized fiber grinding disks (2, 3) such that the vulcanized fiber grinding disk (2, 3) outer faces provided with the grinding means point away from each other and the use of a support plate is not necessary.

Disc-shaped sanding element (1) and method for manufacturing this sanding element (1) with a circular circumference with at least two layers (4,5,6) bonded to each other containing abrasive grains (11, 12), wherein these layers (4,5,6) extend at least to the circumference of the sanding element (1) in order to form a sanding edge (8) on this circumference (7), wherein each of these layers (4,5,6) has layer properties including compressibility, abrasive grain density, abrasive grain size and grain material. The layers (4,5,6) contain a three-dimensional thread or fibre structure in which said abrasive grains (11,12) are distributed, wherein adjacent layers (4,5,6) have at least one different layer property.

The present disclosure relates generally to the field of surface finishing operations, more particularly to micro-finishing systems and processes. The micro-finishing system and process of the present disclosure is configured to perform surface finishing operation on a work-piece. The micro-finishing system comprises: (i) a micro-finishing film having a layer of abrasives which is configured to be rubbed against the work-piece, (ii) a contact tooling which is configured to provide support to the micro-finishing film, and (iii) ports which are configured within the contact tooling strategically to reduce heat and frictional losses generated due to rubbing of the layer of abrasives against the work-piece by a minimum flow of coolant at the desired location. The ports are typically drilled holes.
