发明名称 METHOD AND APPARATUS FOR MANUFACTURING ABRASIVE ARTICLES
摘要 <p>A method for making a nonwoven abrasive article. A preferred aspect of the method comprises the steps of: a) providing a nonwoven web having a first side and a second side, the web comprising a plurality of fibers; b) frothing a liquid make coat precursor; c) applying the frothed make coat precursor to at least the first side of the web in such a manner so as to achieve a substantially uniform coating of the make coat precursor along the fibers of the web; d) spraying a plurality of fine abrasive particles onto the first side of the web, wherein the particles are sprayed so as to form a cloud of abrasive particles that deposit onto the fibers of the web in a substantially uniform distribution; and e) curing the make coat precursor to thereby form a hardened make coat which adheres the abrasive particles to the web and wherein the abrasive particles substantially protrude from the outer surface of the hardened make coat.</p>
