ABSTRACT:
A method and apparatus for tufting weatherstripping involves forming a barrier fin on a substrate, advancing the substrate with the barrier fin extending downwardly from the underside thereof past a tufter head, and passing the downwardly extending barrier fin through a channel in the needleplate of the tufter head while the substrate passes over and is supported by the needleplate. A row of tufts is then tufted along one or both sides of the barrier fin. The barrier fin may be formed by folding the substrate, adhering a strip to the underside of the substrate, or by forming a film from a row of previously inserted tufts. Preferably, the substrate is guided transversely to ensure alignment of the barrier fin or fins between the rows of tufts.
