Abstract
A plurality of sheets are attached together by one or a plurality of thin films or layers of tough flexible material. A film may attach two sheets together firmly or in a releasable manner to permit relative movement between the sheets. In one form of the invention, each film or layer of flexible material is attached by self-bonding to the sheets between which the film or layer is disposed. In another form of the invention, each film is self-bonded to only one sheet and a plurality of films are attached together to attach a plurality of sheets together. The film may carry image transfer material on a complete surface thereof or on a portion thereof, in addition to serving as attachment means for adjacent sheets. In another form of this invention, the film serves only as a means for attachment of adjacent sheets, one to the other. In one form of the invention, the elastic characteristics of the film are employed in urging adjacent sheets to remain in predetermined fixed relationship, while permiting relative movement between adjacent sheets when forces occur which urge such relative movement, such as during folding, or during movement of the sheets over a drum or during angular movement of the sheets and the like.
