ADHESIVE BINDING MEANS FOR EDGE BINDING ASSEMBLED PAGES TOGETHER IN BOOK FASHION

摘要

A strip-like part or cover for edge binding assembled pages to form a book-like assembly, the part consisting of a substrate such as paper bearing three stripe-like formations of heat activated adhesive on one side thereof. The central adhesive stripe is substantially thicker than the other two stripes, and extends along the substrate axis with a width approximately equal to the overall thickness of the book to be bound. The remaining adhesive stripes, which flank the central stripe are preferably comprised of adhesive having a relatively high tack when heated while the adhesive comprising the center stripe has a relatively low tack when heated to facilitate application of the binding stripe. As an alternate, the flanking stripes may be comprised of a pressure sensitive adhesive.
