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

1. A method for producing adhesive-bound, printed items composed of a number of printed products, comprising:

gathering printed products into loose book blocks along a first section of a circulating conveyor, the gathering being conducted while the printed products are positioned transverse to a conveying direction and in a reclined position that is inclined counter to the conveying direction;

supplying the book blocks to an additional conveying section of the circulating conveyor, following the first section;

accelerating the book blocks in the additional conveying section to achieve a greater divisional spacing between the book blocks;

pivoting the book blocks to an upright position such that one side edge of the respective book blocks is in a position approximately parallel to the conveying direction; and

lifting the book blocks up from the parallel position and transferring the book blocks to respective conveying clamps of an adhesive binder.

2. The method according to claim 1 , further including the step of positioning the one side edge to form a spine of the book block after pivoting the book blocks to an upright position.

3. The method according to claim 1 , including exerting a force onto flat sides of the book blocks at least near the end of the first conveying section to hold the book blocks in place.

4. The method according to claim 3 , wherein the exerting step includes exerting the force onto the flat sides of the book blocks prior to the acceleration or pivoting of the book blocks.

5. An arrangement for producing an adhesive-bound, printed item composed of a number of printed products, comprising:

a circulating conveyor comprising a conveying track and a plurality of spaced-apart conveying units driven along the conveying track in a conveying direction, the circulating conveyor further including:

a first conveying section along which printed products are gathered into loose book blocks in the conveying units which are positioned transverse to the conveying direction and in a reclined position that is inclined counter to the conveying direction; and

an additional conveying section to which the book blocks are supplied from the first conveying section for being conveyed to an adhesive binder, wherein the additional conveying section is operative to accelerate the conveying units so that a divisional spacing between the book blocks is increased, and to pivot the conveying units so that the book blocks are moved to an upright position, wherein the conveying units include lifting devices.

6. The arrangement according to claim 5 , and further including circulating conveying clamps arranged above the additional section of the circulating conveyor and driven in a conveying direction and at a conveying speed,

wherein the book blocks are lifted up and transferred to the conveying clamps from the conveying units in the additional section, and

wherein the additional section is driven so that the conveying units move at least during the operation of lifting up the book blocks for the transfer to the conveying clamps at the same speed and in the same direction as the circulating conveying clamps.

7. The arrangement according to claim 6 , wherein the conveying units are adapted to hold the printed products and/or the loose book blocks.

8. An arrangement for producing an adhesive-bound, printed item composed of a number of printed products, comprising:

a circulating conveyor comprising a conveying track and a plurality of spaced-apart conveying units driven along the conveying track in a conveying direction, the circulating conveyor further including:

a first conveying section along which printed products are gathered into loose book blocks in the conveying units which are positioned transverse to the conveying direction and in a reclined position that is inclined counter to the conveying direction; and

an additional conveying section to which the book blocks are supplied from the first conveying section for being conveyed to an adhesive binder, wherein the additional conveying section is operative to accelerate the conveying units so that a divisional spacing between the book blocks is increased, and to pivot the conveying units so that the book blocks are moved to an upright position; and

a holding device installed along the additional conveying section to act upon the loose book blocks, wherein the holding device comprises blast air feeding nozzles.

9. The arrangement according to claim 8 , and further including circulating conveying clamps arranged above the additional section of the circulating conveyor and driven in a conveying direction and at a conveying speed,

wherein the book blocks are lifted up and transferred to the conveying clamps from the conveying units in the additional section, and

wherein the additional section is driven so that the conveying units move at least during the operation of lifting up the book blocks for the transfer to the conveying clamps at the same speed and in the same direction as the circulating conveying clamps.

10. The arrangement according to claim 9 , wherein the conveying units are adapted to hold the printed products and/or the loose book blocks.
