摘要： Methods for preparing abrasive articles and novel methods of making 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. Coated abrasives formed by this method, as well as other methods, are provided wherein an effective amount of a fibrous reinforcing material is engulfed within an organic polymeric binder material. Sufficient binder is present such that there is one or more regions of organic binder material free of fibrous reinforcing material, to which abrasive particles are attached.

摘要： A coated abrasive backing consisting of an endless, seamless, loop is provided. The backing loop includes about 40-99% by weight of an organic polymeric binder, based upon the weight of the backing; and an effective amount of a fibrous reinforcing material engulfed within the organic polymeric binder material. The endless, seamless backing loop includes a length with parallel side edges, and at least one layer of fibrous reinforcing material engulfed within the organic polymeric binder material such that there are regions of organic binder material free of fibrous reinforcing material on opposite surfaces of the layer of fibrous reinforcing material. The fibrous reinforcing material can be in the form of individual fibrous strands, a fibrous mat structure, or a combination of the these. A method for preparing the endless, seamless backing loop for a coated abrasive belt is also provided. The method includes the steps of preparing a loop of liquid binder material having fibrous reinforcing material therein around the periphery of a drum; and solidifying the binder material such that an endless, seamless, backing loop having fibrous reinforcing material engulfed within the organic polymeric binder material is formed.
