ABRASIVE ARTICLE WITH OPTIMALLY ORIENTED ABRASIVE PARTICLES AND METHOD OF MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO2002068154
Kind Code:
A8
Abstract:
The invention provides abrasive articles with optimally oriented abrasive particles (60) and a method of making the same. The method involves contacting a substrate (61) with the contact and mating surfaces of tools to provide an embossed substrate (61) with perforated depressions (62), distributing abrasive particles (60) within the depressions (62) of the substrate (61), optimally orienting each abrasive particle (60) in the depression (62) containing the abrasive particle (60), creating a differential pressure between the top surface and the back surface of the embossed, perforated sheet (61) wherein a lower pressure is applied to the back surface to hold the oriented abrasive particles within its depression (62) while removing at least a major portion of abrasive particles (60) not within the depressions from the top surface of the sheet (61) and permanently bonding the abrasive particles (60) in the depressions (62) and they are optimally oriented to provide the abrasive product.
