Abstract
Cross-head die apparatus and method for applying visually distinguishable coating layers simultaneously to two filament members such as electrical wires. The apparatus includes a body having a pair of generally axial bores and a pair of radial bores respectively communicating between sources of first and second flowable coating materials and the axial bores. A flow guide to direct the coating materials through the axial bores to form uniform layers on wires moved axially through the bores. The two axial bores mutually communicate through an internal conduit, coaxial with the two radial bores, in the body. The two coating materials are supplied at different pressures, causing a portion of the first material to migrate through the internal conduit from one axial bore to the other, whereby the first material forms the entire coating layer on one wire and appears, together with the second material, as a longitudinal stripe in the coating layer on the other wire.
