Abstract

The invention relates to a method for producing collections (15) from a plurality of N (N=2, 3, 4, . . . ) different printed products (11a-d), which collections (15) each comprise a stack (13) of printed products (11a-c), which stack is packed in a packaging element (11d) wrapped around the stack (13). A solution that does not require additional material use includes the following steps: providing the N printed products (11a-d): forming an intermediate stack (13) from N−x (x=1, 2, 3, . . . ) of the N printed products (10a-d); providing the x remaining printed products as a packaging element (11d); and wrapping the intermediate stack (13) in the packaging element (11d).

Claims

1. A method for producing collections from a plurality of N (N=2, 3, 4, . . . ) different printed products having a bond or a fold, which collections each comprise a stack of printed products, which stack is packed in a packaging element wrapped around the stack, comprising the following steps:

providing the N printed products having the bond or the fold;

forming an intermediate stack from N−

x (x=1, 2, 3, . . . ) of the N printed products having the bond or the fold;

providing the x remaining printed products having the bond or the fold as a packaging element;

wrapping the intermediate stack in the packaging element;

wherein the packaging element is laid onto a substratum, and the intermediate stack is laid onto the packaging element in such a way that only a partial area of the packaging element is covered by the intermediate stack, and that the packaging element is wrapped around the intermediate stack by a remaining area of the packaging element not being covered by the intermediate stack; and

wherein, in order to wrap the remaining area of the packaging element not being covered by the intermediate stack around the intermediate stack, the complete remaining area of the packaging element is bent upward approximately at a right angle in a first step and the part of the packaging element bent upward is bent hack over the intermediate stack in a second step.

2. The method according to claim 1, wherein x=1.

3. The method according to claim 1, wherein a unit including the intermediate stack and the packaging element is moved through a wrapping device in order to bend the packaging element.

4. The method according to claim 3, wherein movable elements, which are rotated about an axis of rotation oriented transversely to the movement direction of the unit including the intermediate stack and the packaging element, are used to bend the packaging element in the wrapping device.

5. The method according to claim 3, wherein, after the packaging element has been bent, the bent part of the packaging element is bent back and laid against the intermediate stack by laying the unit including the intermediate stack and the packaging element onto a conveyor belt.

6. The method according to claim 1, wherein some of the printed products have a fold (F) or a bond, that the printed products having a fold (F) or bond are laid one on top of the other during the formation of the intermediate stack in such a way that the folds (F) or bonds form a common edge (K) of the intermediate stack, and that the intermediate stack (13) is wrapped in the packaging element by means of the common edge (K).

7. The method according to claim 1, wherein the packaging elements are grooved before the intermediate stack is wrapped.

8. A device for performing the method according to claim 1, wherein the device comprises a packing device, in which the packaging element lying partially below the intermediate stack is wrapped around the intermediate stack.

9. The device according to claim 8, wherein the packing device comprises a wrapping device and means for moving a unit including the intermediate stack and the packaging element through the wrapping device.

10. The device according to claim 9, wherein the means for moving the unit including the intermediate stack and the packaging element through comprise conveyor segments or conveyor belts lying in a plane, between which a conveying gap is left clear.

11. The device according to claim 10, wherein the wrapping device comprises movable elements, which reach into a conveying path of the unit including the intermediate stack and the packaging element in the conveying gap.

12. The device according to claim 11, wherein the movable elements comprise a brush roller including bristles, which brush roller is arranged in the conveying gap and can be rotated about an axis of rotation oriented transversely to the conveying direction.

13. The device according to claim 11, wherein the movable elements comprise rod-shaped entraining elements, which can be moved through the conveying gap while rotating about a specified axis of rotation.

14. The device according to claim 13, wherein the axis of rotation is oriented transversely to the conveying direction and the entraining elements can perform an oscillatory motion parallel to this axis of rotation at the same time as the rotational motion about this axis of rotation, which oscillatory motion occurs between a first extreme position, in which the entraining elements protrude into the conveying path of the unit including the intermediate stack and the packaging element, and a second extreme position, in which the entraining elements are outside of the conveying path of the unit including the intermediate stack and the packaging element.

15. The device according to claim 14, wherein the rod-shaped entraining elements are arranged on opposite sides of the conveying path of the unit including the intermediate stack and the packaging element in a mirror-symmetric arrangement.

16. The device according to claim 15, wherein, in order to produce simultaneous rotational motion and oscillatory motion, the rod-shaped entraining elements are fastened in a concentric circle to rotary disks arranged at an angle.

17. The device according to claim 15, wherein the simultaneous rotational motion and oscillatory motion of the entraining elements are produced by separate mechanical means.

18. The device according to claim 8, wherein means for feeding the packaging elements to the wrapping device are provided.

19. The device according to claim 18, wherein the feeding means comprise a grooving device for grooving the fed packaging elements.

20. A method for producing collections from a plurality of N (N=2, 3, 4, . . . ) different printed products, which collections each comprise a stack of printed products, which stack is packed in a packaging element wrapped around the stack, comprising the following steps:

providing the N printed products;

forming an intermediate stack from N−

x (x=1, 2, 3, . . . ) of the N printed products;

providing the x remaining printed products as a packaging element;

bending the packaging element via movable elements, which are rotated about an axis of rotation oriented transversely to the movement direction of the unit including the intermediate stack and the packaging element; and

wrapping the intermediate stack in the packaging element.

21. A device for performing a method for producing collections from a plurality of N (N=2, 3, 4, . . . ) different printed products, the collections each comprising a stack of printed products, which stack is packed in a packaging element wrapped around the stack, the method comprising the following steps:

providing the N printed products;

forming an intermediate stack from N−

x (x=1, 2, 3, . . . ) of the N printed products;

providing the x remaining printed products as a packaging element; and

wrapping the intermediate stack in the packaging element, wherein the device comprises;

a packing device, in which the packaging element is wrapped around the intermediate stack;

conveyor segments or conveyor belts lying in a plane, between which a conveying gap is provided, wherein the conveyor segments or conveyor belts convey a unit including the intermediate stack and the packaging element; and

a wrapping device comprising movable elements extending into a conveying path of the unit via the conveying gap.
