Abstract: A presentation folder having a plastic cover sheet or front and back cover sheets joined at a common edge, capable of holding and protecting contents such as papers having information thereon. The cover sheet has pre-applied graphics forming selected opaque display areas, the remaining areas being transparent or translucent and thus capable of revealing at least some of the information on said papers.

Abstract: A book cover formation machine has feeder stations for the cover cloth and cover boards, a glue-application station for the cover cloth, and an assembly station for mating the cover cloth and cover boards. The machine also has a turn-in station with turn-in elements for folding the head and foot flaps over the cover-board edges in a first plane, and for folding the lateral flaps over the cover-board edges in a vertically displaced second plane. The turn-in station is a separate mechanism juxtapositioned to the assembly station. The functions of assembling the cover cloth and boards, of executing the head and foot flap turn-ins, and of executing the lateral flap turn-ins, are coordinated such that all functions within a cycle are performed on different book covers simultaneously.

Abstract: Apparatus and method are disclosed for preparing a preprinted book cover for application to a book block in a perfect binding system A double-walled tubular attachment strip is adhesively attached to the cover spine portion of successive covers in a continuous process. Covers are fed onto a conveyor at a constant speed with a spacing between covers and adhesives is applied to the spine areas. Simultaneously a continuous double-walled attachment strip with a longitudinal lap joint in one wall is formed without adhesive from a source of paper web stock and pressed, lap joint down, onto the cover spines to form a continuous string of covers. The attachment strip is cut by laser cutting beam between each cover while the covers are moving. The double-walled attachment strip is formed by pulling the web under constant tension through side scoring wheels, hold-down shoes, and forming devices which have surfaces to fold the edges of the moving web through 180.degree.

Abstract: A method for binding the book and an apparatus for forming the book cover are disclosed. The forming apparatus comprises a base portion, an anvil member supported by the base portion and a forming bar, preferably heated, which is operatively associated with the anvil member. In operation, the forming bar engages the anvil member, and the cooperation of the forming bar and the anvil member defines the shape of the spine of a book cover positioned therebetween. Reinforced end sheets are secured to a plurality of pages which are then secured by adhesive means to the formed book cover. The book cover so formed securely holds the pages and secures the spine of the book in a durable construction.

Abstract: A filing book with bag sheets comprising a cover sheet and a plural number of bag sheets made of plastics and fixed tightly at the central part of the inside of the cover sheet by heat sealing to form a singly bound book has a structure that the central parts of all of a number of bag sheets are tightly fixed with the cover sheet of paper by heat sealing through an intermediate laminate of paper and plastics film, an intermediate plastic bonding tape or a plastic sheet laminated to the cover sheet.The filing book with bag sheets stands upright firmly, gives comfortable feeling to hands by providing stiffness and smoothness to the cover sheet because the cover sheet is made mainly with paper and, at the same time, can be prepared easily by fixing the bag sheets tightly with the cover sheet by heat sealing even though the cover sheet is mainly made of paper.

Abstract: A method of making a reinforced book or binder cover of polymer or paper covered panels includes feeding a planar panel such as a paperboard panel into a plurality of cutters, then cutting parallel cuts through the panel with pairs of adjacent parallel cutters and stripping the panel portions between the parallel cuts with a stripping member to form a plurality of spaced panels. A polymer hinge strip is fed onto the planar panels over each stripped away portion and is adhered thereto during the stripping step to thereby hold the separated panels in a spaced relationship to each other to form a hinge between panel sections. A polymer covering is adhered over the paperboard and over the polymer hinge strip on one side thereof to form a cover having a flexible hinge between the spaced panel sections.

Abstract: An apparatus for assembling a cover case and a channel binder includes a hopper containing several cover cases. An applicator for applying adhesive on cover cases is positioned adjacent the hopper. A channel placer is adjacent the adhesive applicator. A pusher assembly moves cover cases from the hopper and through the applicator where adhesive is applied to the back of each cover case. Once adhesive has been applied to the back of the cover case, the pusher assembly moves the cover case to the channel placer. In the channel placer, a channel is removed from a channel cartridge and placed on the adhesive on the back of the cover case. Portions of the cover case with adhesive are then pressed to the bottom and sides of the channel, and the cover case with channel is moved to a storage hopper or to a station for securing an end sheet to the inside of the cover case.

Abstract: In the manufacture of a book cover, a cover sheet is glued to cardboard panels and portions of the sheet are folded around edges of the panels. The glued unit is then passed through a press comprising pairs of press rolls spaced apart in the direction of travel of the glued unit. One roll of each pair contains circumferentially spaced recesses along its outer periphery. The recesses prevent the application of pressing forces to the unit when the recesses reach the unit, whereby an interrupted pressing action is achieved. Each pair of rolls is operated to apply pressing forces to regions of the cover not pressed by the other pair of rolls.

Abstract: The present invention is directed to a method and apparatus for making book bindings.

Abstract: A protective book covering including a relatively long piece of sheet material and a relatively short piece of sheet material overlaying the long piece, the longitudinal edges of the two sheets being sealed together. A seal and tear line extending transverse to their longitudinal edges joins the two pieces and forms a line of severance along which the pieces can be torn to produce two units, each unit having a pocket adjacent to the seal and tear line for accommodating one of the covers of a book. One of the units has a section, extending from the pocket of that unit, long enough to wrap around the spine of the book, and be secured to the other unit. The sheet material is preferably transparent plastic. The book covering can be made in a continuous manner by providing independent lengths of relatively wide and relatively narrow plastic sheet material, and placing the lengths in face-to-face contact so that their longitudinal axes extend in the same direction.

Abstract: A protective book cover of transparent plastic is formed with a strengthened spine section provided by a combination of a spine reinforcing strip and decreased height of the spine section of the protective cover. The book cover receiving pockets of the protective cover are formed with inwardly convex slant-cut edges to facilitate insertion of the book covers, and a card pocket is formed in one of the pockets by a slant-cut slit that is convex upwardly to provide an easily accessible opening. A heat weld seam forming the front and back cover pockets is provided with sharp rectangular inside corners for a closer fit of the protective cover to the book. The protective cover is adjustable for book width by forming it of a primary or outside panel that is scored for separation of a back cover portion which may be adjustably positioned and adhesively secured to a front cover portion.

Abstract: In order to form a hard book binding having a middle covering and two side coverings, a unitary covering is first formed by securing the side coverings onto the middle covering; thereafter, a spine member and two coverboard members are attached, in mutually spaced apart relationship, to said unitary covering at the middle covering and the side coverings, respectively.
