Abstract
Abstract A carrier web with recesses or pockets therein which contain pressure sensitive adhesive. The recesses in the carrier web maintain the adhesive in a discrete pattern during handling and storage and prevent lateral flow of the pressure sensitive adhesive under ambient conditions. The patterned adhesive may be transferred to an article directly from the recesses in the carrier by pressing the article onto the carrier web or indirectly by transferring the adhesive first to a cover sheet or to the flat backside of the web and thence to the article.
