Abstract: An adhesive binding strip for binding pages in the form of a book. The adhesive binding strip includes an elongated substrate made of a formable material. A band of heat-activated adhesive runs down the central portion of the substrate. A matrix of heat-activated adhesive is placed on the substrate around all edges of the adhesive band. The matrix is spaced apart from the longitudinal edges of the substrate to form longitudinal regions where tapered adhesive sections of the matrix are disposed. The tapered sections have an average thickness which is at least two-thirds that of the remainder of the adhesive matrix. The adhesive band, which has a low viscosity under activation conditions, binds the pages of a book to each other and to the substrate. The adhesive matrix has a high viscosity under activation conditions, serves to bind the entire substrate to the book, while preventing the adhesive band from running out from under the substrate during the binding process.

Abstract: This invention is a binding case for use in an office-type, small-volume, binding operation employing the hot-melt adhesive binding method. The invention is a design and method which cause the excess hot-melt adhesive which expresses laterally from each side of the adhesive strip to be directed in such a way that the excess adhesive does not adhesively bind the book block to the front or rear cover and does not bring about the destruction in appearance or functionality which such undesirable binding would cause. The invention involves a diverting element which forms a channel for the excess adhesive so that the excess adhesive does not bind the book block directly or functionally to the covers.

Abstract: An expandable capacity album or binder for storing and displaying artwork or photographs retains the appearance of a library bound hardcover book at any state of expansion. The front cover and back cover are hinged to a spine which has page retaining channels that allow looseleaf pages to be inserted into or removed from the album. Together, the spine and the channels are adjustable so that the album will expand and contract for different capacities. The outside of the album is covered with leather or cloth to give the album the appearance of a library bound hardcover book. In between the spine and the covering is a resilient material such as plastic foam which can compress or expand so that the covering will always look properly fitted to the spine even when the spine is expanded or contracted to change the capacity of the album. In this way the album maintains its library bound appearance at any state of expansion.

Utilizing such an adaptor provides a simple efficient means of providing removable covers for a ring binder.

Abstract: An advertising insert is secured, page-like, within a magazine and comprises a folded-over rectangular jacket sheet having adhesively intersecured edge portions positioned opposite its fold line and adhesively secured to an edge flap of an anchor sheet bound into the magazine. The top sheet portion of the folded jacket has formed therein a perforation line positioned closely adjacent and extending parallel to the two intersecured jacket edges which, in turn, extend parallel to the central magazine fold axis. An advertising booklet is removably secured and concealed within the folded jacket, and has a fold axis extending transversely to the magazine fold axis. The concealed advertising booklet may be exposed for removal by tearing the jacket along its perforation line and outwardly folding its top sheet portion. Because the booklet-enclosing folded jacket is open along two of its four side edges it is not classified, under U.S. postal regulations, as an "envelope" or a "pocket".

An elongated, flexible label leader (26) is designed to extend through the slot (24) and protrude therefrom at its opposite ends. An adhesive portion (28) is formed at one end of the leader (26). The label (30) may be inserted into the slot (24) by releasably adhering one end of the label (30) to the adhesive portion (28) of the leader (26), and pulling on the other end of the leader (26), thereby pulling the attached label (30) into the slot (24).

Abstract: A thin wood dimensionally stable flat laminate panel made out of one or more wood veneer sheets attached to one or more sheets of core ply material such as chipboard by adhesive. The thickness of the panel is in the range of from about 0.080 inches to about 0.180 inches. Apertures passing through the panel are positioned around or arranged along the edges of the panel in order to decrease warpage of the panel due to moisture passing to and from the wood veneer sheets at the edges of the panel as a result of moisture passing to the atmosphere from the sheets and from the atmosphere to said sheets. The apertures are preferably spaced the same distance apart. The apertures may be formed by using a commercial sewing machine to position the stitching along the edges of the panel. The stitching provides a capillary "wicking" action facilitating venting of the moisture from the wood veneer sheets to the atmosphere. Stitching may also be used to attach a bias cover material around the edges of the panel.
