ABSTRACT:
A method and apparatus for permanently binding sheets of paper into a cover inexpensively and quickly is disclosed. The cover has a top and bottom leaf with a center fold therebetween and a folding score on each leaf near the center fold. An elongated strip of heat reactivatible adhesive is applied to the inner surface of one or both of the leaves between the folding score on the leaf and the center fold. A plurality of sheets are positioned adjacent the strip or strips of adhesive and the entire assembly is then fed into a laminator machine which heats and presses the heat reactivatible adhesive to cause it to flow back towards the sheets. As the adhesive cools the ends of the sheets are held in intimate contact between the leaves near the center fold.
