Abstract
The disclosure relates to a method and apparatus for the attachment of a zipper to a reclosable package or bag, particular packages or bags of relatively larger sizes. Pinch rollers separate the flanges of the zipper so that the interior walls of the flanges are pointing upward, then hot-melt adhesive is sprayed downwardly onto the flanges. The zipper is then guided over the edge of the horizontally-oriented package or bag by a tube with a longitudinal slot. The package or bag, with the zipper attached, is engaged between a driven-belt apparatus with a nip formed between opposed belts, thereby applying consistent and even pressure to the zipper flanges and assuring that the hot-melt adhesive forms a bond which is consistent, reliable and strong.
