This invention provides a method of making an abrasive article. The method of this invention comprises the steps of: a) providing a backing having a front surface; b) providing a radiation energy transmissive production tool having a contacting surface; c) applying a mixture comprising a plurality of abrasive particles and a binder precursor onto the contacting surface of the production tool; d) causing the mixture on the contacting surface of the production tool to come into contact with the front surface of the backing such that the mixture wets the front surface of the backing; e) transmitting radiation energy through the production tool to at least partially cure the binder precursor to form a shaped, handleable structure; and f) separating the shaped, handleable structure from the production tool. The shaped, handleable structure can be fully cured to form a coated abrasive article.

La présente invention porte sur une méthode de fabrication d'un article abrasif. La méthode comprend les étapes suivantes: a) fournir un support ayant une surface avant; b) fournir un outil de production transmetteur d'énergie de rayonnement ayant une surface de contact; c) appliquer un mélange comprenant une pluralité de particules abrasives et un précurseur de liant sur la surface de contact de l'outil de production; d) amener le mélange sur la surface de contact de l'outil de production à entrer en contact avec la surface avant du support de manière que le mélange mouille la surface avant du support; e) transmettre l'énergie de rayonnement par l'outil de production pour au moins faire sécher partiellement le précurseur de liant de manière à former une structure façonnée et maniable; et f) séparer la structure façonnée et maniable de l'outil de production. La structure façonnée et maniable peut être séchée complètement de manière à former un article recouvert d'abrasif.
