Abstract
Apparatus for and method of manufacturing tire breaker fabric comprising an elongated sheet of parallel closely spaced cords formed from a single cord laid in zig-zag fashion such that the edges of the sheet are formed by a series of folded cord edges. The apparatus comprises a cord laying head for laying a single cord in zig-zag fashion between a pair of spaced-apart edge forming units each comprising a holding pin engageable with a folded cord edge and a pincher head engageable around the pin to crimp the folded cord edge. A collector and holding unit collects the zig-zag cord assembly so formed and is operable to feed each traverse of cord in sequence to a device for applying elastomer to the cord assembly.
