A method of transferring a shaped particle to a substrate includes providing a scrim of at least two elongate strands periodically joined together at flexible bond regions to form an array of apertures between the strands. The scrim is extended along at least one direction to increase the minimum dimension of the apertures. Shaped particles are applied to the extended scrim and at least a portion of the shaped particles enter in at least some of the apertures therein. The extended scrim is relaxed and frictionally retains the particles between the elongate strands. The particle loaded scrim is extended along at least one direction to release and transfer the shaped particles to the substrate in a predetermined orientation.

A sleeve having an outer surface, a sleeve sidewall, a first end, a second end, and at least one gap at either the first end or the second end is positioned within the bag. The sleeve's first end is positioned adjacent the coupler to direct incoming air towards the sleeve and the sleeve is positioned within the bag such that a bypass volume is present between the outer surface and the inner surface.

A structured abrasive article includes a backing having a structured abrasive layer disposed on and secured thereto. The structured abrasive layer includes shaped abrasive composites that comprise abrasive particles and nonionic polyether surfactant dispersed in a crosslinked polymeric binder. The abrasive particles have a mean particle size of less than 10 micrometers. The nonionic polyether surfactant is not covalently bound to the crosslinked polymeric binder and is present in an amount of from 2.5 to 3.2 percent by weight based on a total weight of the shaped abrasive composites. The structured abrasive articles are useful for abrading a workpiece.

Structured abrasive article and method of using the same

Abrasive articles, and methods of making abrasive articles that include a supersize coating or component, such as one configured to inhibit the collection of dust and/or swarf on the abrasive coating. The supersize component can be applied to the abrasive coating after converting the abrasive article with a laser or other conversion mechanism, whether non-contact or mechanical contact. In some embodiments, no fresh or exposed abrasive or backing surfaces exist; that is, the supersize component covers all surfaces.
