US 6,966,553 B2 · Device for preparing adhesive bindings of blocks and brochures, especially for small print runs

Abstract

The present invention pertains to a device of compact design for preparing adhesive bindings of blocks and brochures as well as to a process that can be carried out by means of a device according to the present invention, wherein it has a linear conveying system with clamping rails moving to and fro, whereby the blocks are conveyed in at least two steps. Processing operations are performed on the block during the resulting phases of movement and stop phases. The clamping rails have different shapes at the contact surface toward the block depending on the requirement of the stations fed by them. The complete unit makes possible the universal production of commemorative volumes, brochures and folded brochures and comprises for this purpose the application of end papers, the folding and the application of covers. The end papers are fed flush to the finished spine after the processing of the spine. The gluing of the block spines is carried out at right angles to the height of the block during the stopping of the block by a lifting movement of the gluing mechanism. The feeding of slip-fold strips is coupled with the lifting movement of the gluing mechanism. The delivery is carried out gently by means of a rotatable system of clamping stations.

Dependent claims

A device for preparing adhesive bindings of blocks and brochures in an optimally utilized space, said device comprising:

a conveying device provided with a set of clamping rails for fixing a block or a brochure for moving said block or a stack of papers to be bound through the device, said clamping rails having a pick-up, and a return positions;
a processing unit for preparing a straight block spine;
a pair of feed units for adding end papers to be placed on a front side and a back side of said block or stack of papers, each of said pair of feed units arranged adjacent to and on either side of said processing unit and operates in a direction perpendicular to a conveying direction, each said feed unit further comprising a storage unit for holding a stack of end papers, an end paper separation unit for sucking a lowermost sheet from said stack of end papers, and a pull-off roller-belt transportation unit for pulling, transporting and dropping said lowermost sheet onto an exact end position of said aligning plate to flush align a lower edge of each of two said lowermost sheet with a right and a left lower spine edges of said block or stack of papers;
a gluing station for applying glue to said spine of said block or stack of papers;
and
a delivery device for removing a completely glued said block or stack of papers, wherein said conveying device has a separate holding means for fixing said block or stack of papers being processed in said gluing station during said return of said clamping rails into a pick-up position for a new block or stack of papers.

A process for preparing adhesive bindings of blocks and brochures in an optimally utilized space with a device, in which a block or a brochure is guided through the device by means of a conveying device provided with clamping rails for fixing said block or brochure, wherein

a straight block spine is first prepared in a processing unit,
a front end paper and a rear end paper are each separated from a stack of papers placed on either side of said conveying device, and said end papers are transported in a direction perpendicular to a direction of said conveying device and dropped onto an aligning plate to merge onto the front and rear sides of said block, a spine edge of said end papers aligned flush with a spine edge of said block,
after which glue is applied to said spine of said block or brochure in a gluing station by gluing, and
after a completion of said gluing, a completely glued said block or stack of papers is discharged, wherein
a conveying through the device takes place in at least two steps by a forward and return movement of said clamping rails clamping the block laterally on a left side and a right side when viewed in said direction of conveying,
the block is taken over by a separate holding means during a return conveying stroke of said clamping rails and pass through a conveying stop phase, during which said gluing on said spine of said block takes place, and that processing operations are carried out on said block both during said movement and during a stop.

A compact binding device comprising:

a block conveyer with two opposite clamping rail means for clamping a block, said clamping rail means movable alongside said block conveyer in a conveying direction, wherein said clamping rail means secures an upright block with a spine side facing downward at an intake position and mobilizes said block to top of an aligning plate;
an underneath roller-shaped spine-preparing unit adjacent said intake position;
an end paper applying unit positioned to operate perpendicular to said conveying direction adjacent said aligning plate, said end paper applying machinery further comprising a stack of end papers, a separation means that separates one of said stack of end papers, a guiding means that moves and drops said one separated end paper on said aligning plate, positioning said one separated end paper in a flush position with said block adjacent to said block and merges said one separated end paper flush aligned with said block;
an underneath gluing station under said aligning plate;
a side gluing mechanism at a distance away from said gluing station, for glueing a strip of a side adjoining said spine side as said block is moved along said block conveyor;
a cover applying and conveying station located at a distance away from said underneath gluing station.
