    Abstract: A heat-activatable adhesive article is provided. The article, preferably a tape, includes a substantially laterally stable heat recoverable carrier film having at least one surface comprising a recessed surface portion and a raised surface portion therein; and an adhesive layer in the recessed surface portion in an amount such that the adhesive does not extend above the raised surface portion thereby forming an exposed raised surface portion. In use, the carrier film recovers upon exposure to heat thereby allowing the adhesive in the recessed surface portion to contact a substrate. The heat-activatable adhesive article can be positionable, repositionable, or both.

    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.

    Abstract translation: 一种其中具有凹口或袋的承载网,其中包含压敏粘合剂。 载体网中的凹槽在处理和储存期间将粘合剂保持在离散的图案中,并防止压敏粘合剂在环境条件下的横向流动。 图案化的粘合剂可以通过将制品压在载体网上而直接从载体中的凹部转移到制品上,或者间接地将粘合剂首先转移到覆盖片或幅材的平坦背面,从而转移到制品上。
