  • Patent number: 10137719
    Abstract: A book binding apparatus is provided with a conveyor belt 5 having a book block conveyance surface 13 extending obliquely downward toward a pair of clamp plates 3 and 4 of a clamper 2 at a book block supply position A. A guide plate 21 is attached to the clamp plate 4 on the conveyor belt side and can swing between a standing position and a tilted position. When the pair of clamp plates is placed in a closed position, the guide plate is held in the standing position. When the pair of clamp plates is placed in an open position at the book block supply position, the guide plate swings from the standing position to the tilted position and connects to the book block conveyance surface.

Thereafter, the coating of adhesive material is applied within the holes of the stack so as to entirely coat the paper at the holes or to coat selected portions of the paper at the holes as desired. After the adhesive material has been allowed to cure or has been cured the paper is releasably retained in adhesive bound pad form and the manufacturing process is complete.

  • Patent number: 5193962
    Abstract: Apparatus and method for binding a book utilizing a binding tape having a flexible substrate and a heat activated adhesive. The binding tape is forced against the front cover of the book utilizing a heated platen, so as to form a front cover seal simultaneously along the length of the front cover. The platen then folds the tape around the edge of the book so as to form the spine of the book. The platen then forces the remaining portion of the tape against the back cover so as to form a back cover seal simultaneously along the length of the back cover.

  • Patent number: 5194116
    Abstract: An assembly for applying hot melt adhesive to the backbone of a book block to attach a cover includes a bath of hot melt glue heated to approximately 350.degree. F. A metal wheel is submerged in the bath. The metal wheel is rotated and scrapers meter the hot melt adhesive on the surface of the metal wheel. The metal wheel transfers the hot melt adhesive to flexible adhesive distribution wheel. The flexible wheel is fabricated of a silicone rubber with iron oxide capable of withstanding the elevated temperatures of the hot melt adhesive while maintaining its flexibility. In addition, the cut and mold of the wheel results in greater flexibility of the wheel, allowing the wheel to flex to engage completely the backbone of each book block to apply the adhesive fully and completely.

  • Patent number: 5179141
    Abstract: A latex adhesive made from a polymer such as a ethylene/vinyl acetate or styrene/butadiene copolymer, a low-boiling alcohol, such as isopropanol, a non-crystallizing polyhydric alcohol such as sorbitol, and preferably a cellulose thickener. The latex adhesive dries so quickly that an adhesively edge-padded stack of paper sheets formed using the adhesive can be cut by hand into tablets within about 30 minutes. These tablets do not leave an upstanding ridge of adhesive when a number of the sheets are torn off.

  • Patent number: 5160234
    Abstract: A sheet binder includes a frame having first and second spaced parallel support walls for receiving therebetween a plurality of sheet to be bound. The walls each have a first end for defining therebetween an opening into which the sheets are inserted, and a second end defining therebetween a binding zone. A heating plate and deposition base are operably associated with the second ends for applying an adhesive strip to associated edges of the sheets for binding the sheets together. The plate and base are displaceably supported within the frame for being linearly and alternatingly moved into and out of the binding zone.

  • Patent number: 5129772
    Abstract: A method of manufacturing a soft-cover book of the type having an opening relaxed position in which front and read cover sections may lay flat against a support surface. A collection of pages are perfect bound to form a book block having a spine which is deformable along an arc of 180.degree. without significantly affecting the bond strength of the book block. Preferably, the book block includes a thin flexible capping material across the spine and portions of the opposed sides of the book block. The book block is moved relative to a valved adhesive application station for selective extrusion of adhesive. The adhesive is extruded to form a plurality of adhesive application areas on the spine of the book block, with each application area being spaced apart from adjacent application areas by adhesive-free areas. A soft cover is then brought into contact with the adhesive application areas. Extrusion may be from an elongated outlet which intermittently applied adhesive across the width of the spine.

  • Patent number: 5073076
    Abstract: A device for simultaneously or sequentially edge binding a sheaf of papers and separately laminating single sheets. A heat applying assembly includes a body of heat conducting material having a generally horizontal elongated slot extending through the body and two pairs of rollers, one at an input end of the slot and the other at an output end thereof for feeding a document between two thermoplastic sheets through the slot. Upper and lower imbedded heating coils apply heat above and below the slot for fusing the thermoplastic sheets to effect lamination of the document. The body of heat conducting material provides an upper surface slanted at an acute angle with respect to the horizontal. A rigid guide surface oriented by an equal angle with respect to the vertical provides for gravity retention of a sheaf of paper to be edge bound against the aforementioned upper surface, a heat setting adhesive being introduced along the common end of tyhe sheaf of papers thereby binding the papers along a spine.

  • Patent number: 4958974
    Abstract: An apparatus which adhesively binds a set of sheets by applying a strip having an adhesive on one surface thereof to the spine of the set. The strip is supported on a heated platen which softens the adhesive. The spine of the set of copy sheets is pressed into the adhesive on the strip. The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness. As the spine of the set of copy sheets is moved into contact with the adhesive on the strip, it is damped to absorb a substantial portion of the kinetic energy of the set of sheets to reduce the deflection and distortion of the set of sheets.

    Abstract: A passbook is provided that substantially prevents alteration or counterfeiting. The passbook is formed from a plurality of sheets of flexible material that are bound to one another at selected locations thereon by welding to define a substantially integral stub. The free edges of the welded pages are then folded back over the welded stub such that the stub is disposed interiorly. The welded stub is difficult to disassemble and reassemble without providing some indication of tampering. Furthermore, the disposition of the welded stub enables the passbook to be laid flat without creating stresses on the stub that could result in separation or delamination.
