Abstract
Co-extrusion cross-head die apparatus for applying two coating materials in inner and outer layers to an electrical wire, or the like. A body member has a through, axial bore in which a tip and die members, with respective tip and die holders, are positioned. A pair of radial bores, with which sources of two flowable coating materials communicate, extend from the exterior of the body member to the axial bore. The first coating material flows forwardly of the apparatus through a first flow passage, the second coating material flows rearwardly through a second flow passage, and the two materials flow forwardly, in superposed relation, through a third flow passage from a confluence of the first and second passages to an orifice in the die member where they are deposited in uniform, inner and outer layers, on the wire.
