Abstract: A method of making a coated abrasive article includes at least four steps. In step a), a web is provided comprising a backing having a make layer precursor disposed thereon. The web moves along a web path in a downweb direction, and the web has a crossweb direction that is perpendicular to the downweb direction. The make layer precursor comprises a first curable binder precursor; In step b) an applied magnetic field is provided. In step c), a mixture of magnetizable non-magnetizable particles is passed through the applied magnetic field and onto the make layer precursor such that the magnetizable and non-magnetizable particles are predominantly deposited onto the web in a drop zone according to a predetermined order. At least one of the magnetizable particles or the non-magnetizable particles comprises abrasive particles. In step d), the make layer precursor is at least partially cured to provide a make layer.

Abstract: Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.
