  • Patent number: 4140335
    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.

  • Patent number: 4077824
    Abstract: A continuous business sheet or paper-like web carries image transfer means which is supported by a thin plastics film or layer of tough flexible carrier material. The film or layer of carrier material is removably attached to the sheet and may be removed from the sheet before or after use of the transfer material. Thus, when desired, the transfer material is removed from the business sheet by removal of the carrier material and the business sheet is thus freed from the transfer material and from any problems which may be associated therewith.
