Abstract: A method and an apparatus for producing folders of the kind comprising two cover sheets, a spine, which is connected with the cover sheets by means of creasing lines, and a binding agent, which is applied to the inside of the spine and which is activable to connect sheets inserted between the cover sheets to the spine. The binding agent is applied to the spine and to the cover sheets while the cover sheets are essentially parallel to each other and perpendicular to the spine.

Abstract: An apparatus for glueing together two different material layers, of which one is intended to form a first cover in a folder, file or the like and the other a second cover and/or a spine in the folder, file or the like, the glueing being carried out in an area where the layers overlap each other, by a glueing device included in the apparatus, said device coating one side of one layer with a glue strip along or close to one edge thereof. The apparatus also includes an aligning means (23, 25), which aligns both layers relative each other so that they overlap each other in an area which is at least as wide as the width of the glue strip, a pressing means (26, 28) pressing both layers towards each other in the area for the glue strip therebetween, and a feed means (6-10, 15-18, 29-32) for feeding the layers through the apparatus.

Abstract: An apparatus is provided for folding a sheet (1) into a folder provided with a spine and at least one cover. In the portion of the sheet forming the spine of the folder after folding, there is applied a bead (2) of binder for binding sheets of paper, inserted in the ready folder, to the inside of the spine. The sheet is advanced with the bead parallel to the advancing direction via a rail (14) guiding the bead to folding and back-up means implemented as rollers (15, 16, 19, 20), for folding the cover side against the inside of the spine along a line situated closely adjacent and parallel to the bead.

Abstract: In a method for producing book covers, a folder, a booklet or the like having a blank (7) with at least one cover and a spine (3) connected thereto via at least one crease line (4, 5) and a bonding agent or binder for adhering pages or the like inserted in the book covers, folder, booklet or the like to the inside of the spine. To this end the binder is placed in the form of a strip (6') on a base (13) so that both longitudinal side edges of the strip are oriented between two creasing means (11, 12) projecting above the surface of the base, and the blank is aligned into a predetermined position above the base and creasing means, there also being a press means (14) for pressing the blank against the creasing means and strip to form the crease lines and to attach the strip to the inside of the spine. An apparatus for carying out the method comprises a base (9, 10) for the strip (6'), creasing means (11, 12) for orienting the strip, and a press means (14).
