Document Type and Number:
Japanese Patent JPH08511479
Kind Code:
A
Abstract:
Methods for preparing flexible, endless, seamless substrates suitable for use in making abrasive articles, and abrasive articles, are presented. One method includes inserting a fibrous material adjacent an interior surface of a drum. A composition comprising an organic binder precursor material is then placed in the drum, and the drum is rotated such that centrifugal forces distribute the composition, including the organic binder precursor material, uniformly about the fibrous material. The composition is exposed to conditions sufficient to solidify the organic binder precursor material such that an endless, flexible, seamless substrate is formed having an outer surface formed adjacent the interior surface of the drum, an inner surface opposite the outer surface and the fibrous material embedded therein.
