ABSTRACT:
Adhesive, preferably pressure sensitive adhesive, is applied to an article f manufacture, such as the closure flap of an envelope or paper bag in such a way that the adhesive is protected against activation prior to closing the article. For this purpose, the adhesive is first applied to a continuous web or tape of a carrier material that either has an inherent anti-stick characteristic or is provided with an anti-stick surface coating relative to the adhesive to be applied. Preferably, the adhesive does not cover the entire surface of the carrier strip, but rather covers only areas in the form of stripes extending at least partly across the width of the carrier web. The adhesive stripes are spaced from one another and preferably also from at least one edge of the carrier web or tape. The carrier web is then severed into strips, each provided with one adhesive stripe and these strips with the adhesive stripes thereon are then secured between two rollers to the surface area to be provided with the adhesive. The web material forms a substrate or backing for each individual adhesive stripe. The backing is then removed when the article is to be closed. The apparatus for this purpose is provided with a feed advance for the tape or web, with an adhesive applicator and with a cutter that preferably also functions as a strip applicator.
