Abstract: The present invention is an operator replaceable cartridge which is used in an apparatus for binding together a plurality of sheets to form a bound booklet. The flow of adhesive stored in the chamber of the housing is regulated to control the distribution of the adhesive on an applicator blade. The applicator blade is mounted on the housing and is of the length at least equal to the length of the marginal region of the sheet. In operation, the applicator blade reciprocates into and out of contact with the marginal region of the sheet to form a line of adhesive thereon.

Abstract: A sheet for binding loose pages together in pamphlet form comprises a thin flexible sheet having a band of pressure sensitive adhesive coated along one longitudinal edge and protected by a release liner. The sheet permits binding the sheets easily by hand.

Abstract: The invention relates to a gluing apparatus which can be used in particular as part of a book casing-in machine. The gluing apparatus includes an application roller for applying a glue layer to a surface to be glued and a dosing roller for dosing the amount of glue. The application roller comprises an axis-parallel depression and the dosing roller comprises an axis-parallel projection engaging in the depression. The profile of the projection (20) of the dosing roller (2) merges from the cylindrical peripheral surface (4) via an involute into a coaxial cylindrical portion (22) of greater diameter while the profile of the depression (10) of the application roller (1) merges from the cylindrical peripheral surface (3) via a curve forming the counter profile to the involute of the projection (20) into a coaxial cylindrical portion (12) of smaller diameter.

Abstract: Stacks of paper sheets are transported at a level above a heated paste tank and their lower edge faces are contacted by the upper portion of the peripheral surface of a driven wheel-shaped applicator whose lower portion dips into the supply of paste in the tank and an intermediate portion of which is located above the upper level of the supply of paste and upstream of the upper portion. The intermediate portion of the peripheral surface receives a mixture of paste and air from a spray nozzle which, in turn, receives the mixture from a conduit containing a mixer and a pump and having an intake end immersed in the supply of paste in the tank. The pump draws air or another gas into the conduit by way of a pipe upstream of the mixer, and the latter converts the supplied paste and gaseous fluid into a foam which is delivered to the orifice of the nozzle.

Abstract: A copying machine/finisher system is disclosed as having a rotary sorter arranged to receive a stream of copy sheets produced by a processor in conjunction with an automatic document handling apparatus of the type which produces multiple copies of a document sheet placed at an exposure station. The sorter collates the stream into booklets as the sorter is rotated in an indexing manner. An adhesive binder and a stapler are selectively positioned to effect binding while the booklets are still in the bins of the sorter. Binding is effected in timed relationship with sheets still entering the sorter. The sorter/finishing apparatus may also be a stand alone system.

Abstract: A flyleaf heat sealer for adhering a flyleaf having its inner surface pre-coated with hot melt or heat sensitive adhesive to the exposed outer surfaces of the end sheets of a book block insert, includes means for engaging and transporting a book block insert and the flyleaf folded therearound, means for directing a flow of air heated to a temperature adequate to melt the adhesive against and impinging upon the outer surfaces of the flyleaf, and means for pressing and cooling the flyleaf and book insert between them and removing heat from the flyleaf and book block, and thus curing and hardening the adhesive.

Abstract: The invention is concerned with the field of devices for spread-applying liquids, and in particular, with a device and method for spread-applying glue on the spine region of a book.The technical problem to be solved was that of providing bookbinding machines which could spread glue controllably and evenly, and apply said glue on all the suitable locations for glueing and only there.The problem is solved by providing a device which has a pair of containment lateral sides arranged at extrusion nozzles and alongside the path followed by said book spines, said lateral sides being movable to and away from each other and defining an extrusion chamber which envelopes both said spine and book edges adjacent it, and has a working chamber operative to supply said nozzles with glue and being confined between two juxtaposed pressure elements which are movable together with said containment lateral sides.

Abstract: A binding strip for binding a stack of sheets together in a book-like fashion. The binder strip includes an elongated substrate made of a formable material such as a strip of heavy paper. A relatively wide band of heat-activated adhesive extends down the center of the substrate. Two relatively narrow bands of heat-activated adhesive are disposed on opposite sides of the central adhesive band. The central adhesive band, which has a low viscosity at the application temperature, serves to bind the edges of the sheets together and to the substrate. The side adhesive bands, which are at least one-half as thick as the central adhesive band and which have a high viscosity at the application temperature, functions to secure the first and last sheets of the stack to the substrate. The first and last sheets serve as the cover sheets of the bound volume. The side adhesive bands also function to contain the low viscosity central adhesive during the binding process.

Abstract: A sheet stack is bound by applying adhesive with a drum from which adhesive is wiped just before the stack arrives to prevent excess adhesive on its front edge. Other features include a sheet-aligning jog table that moves out of position before the stack reaches the drum, the use of separators between a plurality of stacks that travel past the drum simultaneously, and a bound stack of sheets with a cover having a small, folded-over portion adjacent to the stack.

Abstract: An adhesive binding machine which is for gluing the covers to the collated pages of the books and which includes a cutter for trimming the edges of the pages, a glue pot for applying glue to the cut edges, a nipper for pressing a cover to the glued edges of the pages and pinching it around the pages.

Abstract: A binding apparatus, for attaching loose sheets to a folder or file provided with a binding agent, comprises a hotplate (2) against which the folder is inserted through an opening (4) defined between supporting means (5, 6). The hotplate is kept constantly heated, while a time circuit controlled by means of a push button unit (10) activates an alarm means (12) when a set time is at an end. The regulatable time circuit is always zeroed when the folder is taken out of the opening, since the folder affects a light beam across this opening to a photocell which is connected to the time circuit (FIG. 1).
