Abstract: The invention pertains to a fabric covered book cover having front and back leafboards and a spine wherein both leafboards are covered with a fabric material. One characteristic feature of the book cover is that the spine includes a plurality of longitudinal parallel seams which permit the spin to curl slightly and to fit comfortably in the cupped palm of the hand.

Abstract: A convertible ring binder incorporates front and back covers that are detachable one from the other to enable exchange of the covers for new or different covers. Hook and loop material is utilized to effect detachable attachment of the covers. In another aspect, the ring structure utilized to store paper in the binder is detachably secured to the spine of a loose-leaf ring binder.

Abstract: An adaptor for a ring separator is attached to a conventional ring separator mechanism and provides a means for attaching removable covers to form a binder. The adaptor has a plurality of slots on each side requiring a cover, with at least one slot on each side having an upwardly extending projection which is matable with a hole in a removable cover. The removable cover also has a notched edge with extending portions being receivable slots in the adaptor. When pressed into the slots, the projection engages the hole to hold the cover in place. Utilizing such an adaptor provides a simple efficient means of providing removable covers for a ring binder.

Abstract: A protective cover for a book including cover sleeves consisting of two overlaying sheets bonded together along three edges adapted to fit over book covers or the like. Each cover having a plurality of tear away strips along an open end of the sleeve. Each of the strips bearing a line pressure sensitive adhesive overlaid with a removable protective facing. A line of pressure sensitive adhesive is positioned along the closed end opposite the strips and on the same side of the sleeve as the adhesive on the strips. An elongated narrow spine piece adapted to engage a book spine having a plurality of tearaway strips at least on one narrow end of the spine. Lines of pressure sensitive adhesive along the long edges of the spine piece on the same side thereof. Easily removable protective facing on each of the spine adhesive lines. When the cover is installed on a book or the like there is no attachment to the book surface.

Abstract: A device to facilitate organization of educational and business schedules and paperwork, simultaneous with conveying varied graphic and social images. The device is a ring binder in which a time piece is mounted for easily viewing the time display. A pocket is provided on the front cover of the device for receiving and easily changing opaque and transparent imprinted sheets to alter appearance, while exposing the time display.

Abstract: A binder is provided having a cover featuring a three-dimensional design produced by depressing plastic cover sheets into an opening in an underlying cover panel. The cover sheets are heat sealed together around the perimeter of the cover panel and in the regional of the depression. A plurality of such openings may be provided, all so shaped and positioned as to avoid substantially impairing the structural integrity of the cover.

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.

Abstract: A binder having recesses at both sides of the spine to enable easy grasping for removal from a shelf. The spine recesses also facilitate carrying of the binder. Carrying of the binder is additionally facilitated by a hand-hold recess opposite the spine recesses.

Abstract: A process for the formation of the hinge joints on bound book blocks using a hot melt pressure sensitive adhesive comprising:(a) 20 to 35% by weight of an A-B-A block or A-B-A-B-A-B multi-block copolymer where the A component is styrene and the B component is butadiene or hydrogenated butadiene and the copolymer contains at least 28 parts styrene per 100 parts copolymer;(b) 45 to 70% by weight of a compatible tackifying resin;(c) 5 to 30% by weight of a plasticizing oil;(d) 0 to 5% by weight of a petroleum derived wax; and(e) 0.1 to 2% by weight of a stabilizer.

Abstract: Loose pages can easily be bound in a cover having a strip of aggressive pressure sensitive adhesive near the fold line by aligning the pages with the outer edge and then rolling the inner edge of the cover and pages to shingle the edges along the adhesive to attach each page.

Abstract: A novel inexpensive but durable book cover is provided which enables hard cover books to be provided at a substantially decreased cost with respect to conventional hard cover books. The binder comprises cover members comprising overlying panels which are joined to provide pockets in which may be received the cover of a paperback book and a spine hinged to the cover members through fold lines. The interiors of the pockets are embossed to aid in the insertion of the paperback book covers.
