Abstract
Apparatus and method for producing, on a commercial scale, forming tubes of high quality and uniformity including one or more beads on the outer periphery of the tubes which terminate a desired distance from the tube end edges by sequentially cutting the bead cord material to the desired length and at the desired time relative to the tube ends and feeding such cut bead cord material between selected tube plies during the winding of the plies on a mandrel to form tubular material and then cutting the tubular material to form tubes of the desired length. Also, such apparatus and method provide for the picking up and rolling of the beads which are interrupted on the outer periphery of the tubular material and the subsequent cutting of the tubular material intermediate such bead interruptions.
