An abrasive belt is provided which comprises a textile fabric being formed of interconnected yarns, and a coherent abrasive area formed on one side of the textile fabric, wherein the abrasive belt further comprises a plurality of regularly distributed openings in the form of through holes. The abrasive belt allows for a homogenous distribution of the abrasive material and thus an even sanding finish as well as for an appropriate dust removal and appropriate mechanical properties.

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.

A grinding wheel includes an elastomerically deformable supporting layer, at least a first metallic surface fastened to the elastomerically deformable supporting layer, the metalic surface being an elastically deformable metal foil and includes abrasive particles attached to the at least one metalic surface. The particles may include at least one of: cubic boron nitride or diamonds. The metal foil may have a thickness of less than 1 mm. The abrasive particles may be bonded galvanically on the metallic surface. The abrasive particles may be bonded on the metalic surface in a plurality of areas having regions without abrasive particles therebetween. The metal foil may be adhesively bonded onto the elastomerically deformable supporting layer. The elastomerically deformable supporting layer may be plastic foam. The elastomerically deformable supporting layer may be adhesively bonded onto a metallic supporting body.

A grinding plate for a grinding disk of a grinding machine, wherein the grinding plate has a basic body and a Velcro hook layer with Velcro hooks. The basic body of the grinding plate includes a fiber-reinforced plastic and the Velcro hook layer comprises a nonreinforced plastic. A method for producing such a grinding plate is also provided. The Velcro hook layer can be molded as a thin layer of nonreinforced plastic onto the basic body made of a fiber-reinforced plastic. The grinding plate can be produced in particular in a two-component injection molding method.

This invention relates to compressed composite backing materials (e.g., compressed polymer impregnated backing substrates) and coated abrasive articles that include such compressed composite backing materials. This invention also relates to methods of making and using said compressed composite backing materials and coated abrasive articles. The claimed processes and systems related to the use and manufacturing of coated abrasive articles are improved and cost effective.

The present invention relates to a support for an abrasive comprising a nonwoven fabric being a through-air thermally bonded nonwoven fabric comprising multicomponent binder fibers. The present invention relates also to a method of forming said support and to the use of said support in the manufacture of an abrasive article.

The present disclosure relates to abrasive aggregates comprised of abrasive particles in a vitreous binder composition, and methods of making and using such abrasive aggregates, including in abrasive articles. The abrasive aggregates can include modifier particles. The abrasive aggregates can include a layer of outer particles on at least a portion of the outer surface of the abrasive aggregate.

A nonwoven abrasive article includes a lofty open nonwoven fiber web comprising entangled fibers; and abrasive platelets secured to the entangled fibers by at least one binder material. A majority of the abrasive platelets are respectively bonded in an edge-wise manner to at least one of the entangled fibers. Methods of making the nonwoven abrasive article and converted forms, including a convolute abrasive wheel, are also disclosed.

Aspects of the present disclosure relate to a method of making an abrasive article. The method can include providing a combination of a mesh backing and a fastener. The mesh backing has a first side and a second side and the mesh backing has a fastener disposed on the second side and intertwined through the mesh backing therein. The combination comprises a raised portion on the first side having a first dimension. The method can include calendering the first side of the mesh backing to form a calendered mesh backing such that the raised portion results in a second dimension. The second dimension is less than the first dimension. The method can include depositing a curable make layer precursor on a major surface of the calendered mesh backing, deposing a plurality of abrasive particles onto the curable make layer precursor, and at least partially curing the curable make layer precursor.

An abrasive article comprises abrasive particles adhered to a substrate by a binder material comprising an at least partially cured resole phenolic resin and an aliphatic tack modifier. The amount of resole phenolic resin comprises from 60 to 98 weight percent of the combined weight of the resole phenolic resin and the aliphatic tack modifier. A method of making the abrasive article is also disclosed.
