Abstract
The present invention provides an apparatus for continuously coating aligned cords having knots or other enlarged irregularities therein. A cord-alignment baffle means of novel construction located at the cord entrance of an extrusion coating die assembly enables passage of splices such as knots. The baffle means comprises a plurality of cord-alignment apertures, each of which comprises a guide position and an enlarged knot-passing position. During operation of the coating process, cords are maintained in alignment as they pass through the die, and intermittent knots pass through the enlarged knot-passing positions of the alignment apertures. A bleed means controls the pressure within the extrusion chamber to prevent undesirable backflow through the enlarged knot-passing positions of the alignment apertures.
