Abstract
An apparatus for cutting segments from a long sheet of multilayered elastomeric material. An initial opening is formed in the sheet without severing reinforcing cords within the elastomeric sheet by a penetrator/separator. Two ultrasonic knives are inserted on either side of the penetrator/separator and positioned to cut the sheet at a small skive angle &agr; with respect to the plane of the sheet being cut. Then the knives are moved to opposite edges of the sheet of elastomeric material.
