  • Method of making coated abrasive belt with an endless, seamless backing
    Patent number: 6406576
    Abstract: 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.
