Abstract (en)
[origin: WO2018063958A1] In some examples, an abrasive particle transfer system including a production tool comprising a dispensing surface and a back surface opposite the dispensing surface, wherein the production tool has cavities formed therein, wherein, on a respective basis, each of the cavities extends from a first opening at the dispensing surface through the production tool to a second opening at the back surface, and wherein the second opening is smaller than the first opening; abrasive particles removably disposed within at least some of the cavities such that a portion of each particle protrudes from the back surface through the second opening; and a transfer roll having an outer surface, wherein the production tool is guided along a web path such that the portion of the abrasive particles protruding from the back surface of the production tool contacts the outer surface of the abrasive particle transfer roll to displace the abrasive particles.
