Adjusting apparatus and method for a folding-unit cylinder

1. An adjusting apparatus of a folding-unit cylinder for actuating members which guide folded products, comprising:

a linkage which is set longitudinally such that a length of the linkage defined by a first end of the linkage to a second end of the linkage is adjustable by an adjusting drive which is arranged in the folding-unit cylinder; and

an adjusting member which is articulated on an output side of the linkage such that the adjusting member is rotationally driven by the linkage, is mounted so as to be rotatable about an axis of the folding-unit cylinder, and actuates the members which guide the folded products.

2. The adjusting apparatus according to claim 1 , wherein the adjusting drive has an output shaft to which a bevel gear wheel is fitted which meshes with at least one further bevel gear wheel which is fitted onto a spindle, and wherein the further bevel gear wheel drives the spindle.

3. The adjusting apparatus according to claim 1 , wherein the adjusting drive is configured as an electric motor.

4. The actuating apparatus according to claim 1 , wherein the adjusting member is provided with an outer crown gear, wherein a pinion engages into the crown gear, and wherein the pinion drives a shaft which is mounted on the folding-unit cylinder with shaft sections, engages into a tubular support with eccentric shaft sections, and has a connecting section between the shaft sections, and further wherein the tubular support bears a member which is deployable radially to guide the folded products.

5. The adjusting apparatus according to claim 4 , wherein the tubular support is connected fixedly to a second tubular support by a guide rod in order to secure the tubular supports against rotation.

6. The adjusting apparatus according to claim 4 , wherein the member is configured as a circumferential section of a gathering cylinder.

7. The adjusting apparatus according to claim 1 , wherein the adjusting member is connected fixedly to a member which is positionable in a circumferential direction and guides the folded products.

8. The adjusting apparatus according to claim 7 , wherein the member which guides the folded products is configured as a fixed folding-jaw part.

9. The adjusting apparatus according to claim 1 , wherein the adjusting member bears a pivot axis of a member wherein the member grips the folded products for guidance purposes.

10. The adjusting apparatus according to claim 9 , wherein the member that grips the folded products is configured as a folding jaw.

11. An adjusting apparatus of a folding-unit cylinder for actuating members which guide folded products, comprising:

a linkage which is set longitudinally by an adjusting drive which is arranged in the folding-unit cylinder; and

an adjusting member which is articulated on an output side of the linkage, is mounted so as to be rotatable about an axis of the folding-unit cylinder, and actuates the members which guide the folded products;

wherein the linkage has a rotatable spindle which is mounted so as not to be displaceable in a longitudinal direction and has an outer threaded part, wherein the outer threaded part engages into a threaded bush which is coupled to the adjusting member by a bolt.

12. The adjusting apparatus according to claim 11 , wherein a threaded connection between the outer threaded part and the threaded bush is a self-locking configuration.

13. An adjusting apparatus of a folding-unit cylinder for actuating members which guide folded products, comprising:

a linkage which is set longitudinally by an adjusting drive which is arranged in the folding-unit cylinder;

an adjusting member which is articulated on an output side of the linkage, is mounted so as to be rotatable about an axis of the folding-unit cylinder, and actuates the members which guide the folded products; and

a slip ring which is connected fixedly to a shaft of the folding-unit cylinder and which interacts with a current-conducting contact which is attached to a fixed wall of the folding unit, wherein the current-conducting contact is arranged such that it is movable off of the slip ring.

14. The adjusting apparatus according to claim 13 , wherein a shaft is provided with a cam which moves the current-conducting contact off of the slip ring.

15. An adjusting apparatus of a folding-unit cylinder for actuating members which guide folded products, comprising:

a linkage which is set longitudinally such that a length of the linkage is adjustable by an adjusting drive which is arranged in the folding-unit cylinder; and

an adjusting member which is articulated on an output side of the linkage, is mounted so as to be rotatable about an axis of the folding-unit cylinder, and actuates the members which guide the folded products;

wherein the linkage has a rotatable spindle which is mounted so as not to be displaceable in a longitudinal direction and has an outer threaded part, wherein the outer threaded part engages into a threaded bush which is coupled to the adjusting member by a bolt.

16. The adjusting apparatus according to claim 15 , wherein a threaded connection between the outer threaded part and the threaded bush is a self-locking configuration.

17. An adjusting apparatus of a folding-unit cylinder for actuating members which guide folded products, comprising:

a linkage which is set longitudinally such that a length of the linkage is adjustable by an adjusting drive which is arranged in the folding-unit cylinder;

an adjusting member which is articulated on an output side of the linkage, is mounted so as to be rotatable about an axis of the folding-unit cylinder, and actuates the members which guide the folded products; and

a slip ring which is connected fixedly to a shaft of the folding-unit cylinder and which interacts with a current-conducting contact which is attached to a fixed wall of the folding unit, wherein the current-conducting contact is arranged such that it is movable off of the slip ring.

18. The adjusting apparatus according to claim 17 , wherein a shaft is provided with a cam which moves the current-conducting contact off of the slip ring.
