Abstract
Abstract A wire stripper wheel, of the type having a plurality of layers of woven glass fibers impregnated with and bonded together with a rubber substance, has an additional layer at each end formed with a hard bonding substance such as epoxy resin or polyester. The hard layers cut through tough plastic insulation and hold the glass fibers compressed so they do not fray endwise of the wheel.
