  • Method for fabricating a sawtooth clamp cushion
    Patent number: 4788021
    Abstract: A method of fabricating a clamp cushion for use with a clamp device for mounting and restraining wires. Uncured resilient material is extruded through an extrusion die to form an extrusion having a raised upper surface on one side and, on the other side, a passageway being defined by longitudinal side walls and cover flaps to accommodate the clamp device. A toothed surface is then pressed into the raised surface of the extrusion to form a plurality of longitudinally spaced transverse nodes.
