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 temporary layer comprising 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;
embossing the layer comprising softened particulate curable binder
material and abrasive particles to provide a pattern of raised areas and
depressed areas and curing the softened particulate curable binder
material to convert the embossed layer into a permanent embossed layer
comprised of cured particulate binder material and abrasive particles and
cure the at least partially cured primer coating on the first surface of
the backing. The invention also provides an abrasive product having an
embossed surface made by the method.
