Abstract
The invention provides a method and apparatus for making an abrasive product comprising providing a substantially horizontally deployed flexible backing having a first surface bearing an at least partially cured primer coating and an opposite second surface; providing a dry flowable particle mixture comprising abrasive particles and particulate curable binder material; depositing a plurality of temporary shaped structures comprised of said particle mixture on the at least partially cured primer coating of the first surface of the backing; softening said particulate curable binder material to provide adhesion between adjacent abrasive particles; and curing the softened particulate curable binder material to convert said temporary shaped structures into permanent shaped structures and cure the at least partially cured primer coating on the first surface of the backing. The invention also provides an abrasive product made by the method.
