ABSTRACT:
A method of manufacturing a friction band useful as either a brake band or a transmission band is provided. The band includes an arcuate metallic strip lined with a frictional strip. These strips are adhered together while in a flat, straight condition. The adhered strips are then formed into a generally arcuate shape, with the lining strip on the interior. Brackets are then provided on each free end of the metallic strip. The brackets are welded to the metallic strip. Sufficient area of the metallic strip is exposed in the area of the brackets to permit use of closely adjacent electrodes against the bracket and metallic strip.
