A method for producing adhesive-bound book blocks from gathered signatures for which the individual signatures forming a non-bound book block are supplied while positioned on the spine on a transfer section to an opened conveying clamp on a perfect binder and are subsequently held while clamped in by the closed conveying clamp along the flat outer surfaces. The gathered signatures of a book block are released in an additional conveying section from the conveying clamp in order to be aligned while guided. Prior to leaving the conveying section for aligning the signatures, the signatures are clamped in once more by the conveying clamps along the flat outer surfaces, so that they can be conveyed to further processing locations.

Method for producing adhesive-bound book blocks from gathered signatures

An apparatus is provided for pressing a casing or a slip-fold against an adhesive-covered back and adjacent side flanks of a book block, which is conveyed while clamped into a circulating clamp of a perfect binder with the book back projecting downward. The apparatus includes a back pressing device for pressing the casing against the adhesive-covered back and a flank pressing device for pressing the casing against the side flanks. These devices are driven synchronized with the timing of the book binder clamps for conveying the book blocks. At least the flank pressing device is assigned an individual drive unit which is connected to a control device of the perfect binder.

Apparatus for pressing a book casing or a slip-fold against an adhesive-covered back

A method and arrangement is provided for producing an adhesive-bound printed item composed of a plurality of printed products. The printed products are gathered into loose book blocks along a first conveying section of a conveying track for a circulating conveyor while positioned transverse to a conveying direction and inclined counter to the conveying direction. The book blocks are then accelerated in an additional section of the circulating conveyor to obtain a larger divisional spacing between the printed products. The book blocks are transferred from the additional section of the circulating conveyor to clamps of a transporter and pivoted to an upright position where one side edge is approximately parallel to the conveying direction. The book blocks are transferred from the clamps of the transporter into respective circulating conveying clamps of an adhesive binder.

Method and arrangement for producing an adhesive-bound printed item composed of several printed products

A glue applicator for applying an adhesive to the spine of a book block or to adjacent areas of a book block of stacked printed sheets being conducted past the glue applicator includes a tank holding liquid adhesive, into which at least one glue applicator roll dips to take up the adhesive and to transfer it to the spine of the book block, the roll being driven in the same travel direction as the book block, wherein the glue applicator roll works together with a doctor blade which is installed above the surface of the glue in the tank, and wherein the doctor blade determines the thickness of the adhesive film to be transferred to the spine of the book block through variation of its distance from the glue applicator roll, and where an actuating element for the doctor blade is positively connected to a cam disk, which is driven by a motor.

A glue spreader for spreading glue to a back or adjacent area of a book block of gathered printed pages conveyed past the glue spreader on a conveyor includes a tub for holding the glue. At least one application roller, drivable in the same direction and at the same speed as the book block, is submerged in the tub in order to take up the glue and transfer the glue to the back of the book block. A blade coater is adapted for arrangement above the glue level in the tub at a changeable distance to the application roller. An actuation element is coupled to the blade coater for adjustment of the blade coater for determining a thickness of a glue film to be transferred to the book block back based on the changeable distance to the application roller. A controllable electric motor has a drive element and the actuation element of the blade coater is operatively connected to the drive element of the controllable electric motor.

Glue spreader

An applicator for applying an adhesive to a spine or adjoining regions of a book block conveyed guided past the applicator along a conveying plane in a conveying direction includes a trough for holding the adhesive. At least one applicator roller protrudes into the trough and is arranged for transferring adhesive onto the spine of the book block for forming an adhesive layer on the spine. The roller is driven in a direction which is the same as the conveying direction and defines an approach region in which the surface of the roller approaches the conveying plane. A sharply-pointed separating wedge is disposed downstream of the approach region of the applicator roller and forms a separating region for the supplied adhesive between the applicator roller and the conveying plane of the book block.
