ABSTRACT:
Instead of being butt-spliced, thermoplastic tapes used to form yarn used by carpet manufacturers are sealed along a longer bias of their off-centered, cross alignment, (providing greater strength but without additional bulk) by means of a heating wand and method of the present invention. The wand includes means for first untwisting the tapes over a short segment thereof and then placing them in relative cross-alignment positions relative to a transversely located heating element. The heating element is in intermittent circuit with an energy source.
