Abstract
Abstract For accepting folded products (5) and transporting them further, a revolving belt or chain system (7) on which drivers (8) are provided is used following the transfer point between a folding blade cylinder (1) and a folding gripper cylinder (2). After the folded spine (6) has been grasped by the folding grippers (4) of the folding gripper cylinder (2), drivers (8) are laterally inserted into the wedge-shaped region A, after which the folding grippers open. Then the drivers (8) accept the folded products (5) from the folding gripper cylinder (2) or the folding blade cylinder (1) and guide them further, preferably in a suspended condition, for further handling.

Claim 1
Independent Claim
175 words
Device on a folding gripper cylinder to accept and further transport the folded products provided between a folding gripper cylinder and a folding blade cylinder with a crosswise fold, by means of a revolving transport device, characterized in that the revolving transport device (7), provided with drivers (8), is arranged in the approximately wedge-shaped region (A) behind the transfer point of the folded product (5) from the folding blade cylinder (1) to the folding gripper cylinder (2), that the drivers (8) are positioned on the transport device (7) in such a manner that one driver at a time, after the insertion of the folded product (5) into the folding gripper (4) of the folding gripper cylinder (2) is inserted engagingly into the region (A) between the two halves (5a, 5b), which are still resting on the folding blade cylinder (1), and that after the release of the folded product (5) by the folding grippers (4), the drivers (8) transport the folded products (5) further after they have been removed from the folding gripper cylinder (2).

Device on a folding gripper cylinder to accept and further transport the folded products provided between a folding gripper cylinder and a folding blade cylinder with a crosswise fold, by means of a revolving transport device, characterized in that the revolving transport device (7), provided with drivers (8), is arranged in the approximately wedge-shaped region (A) behind the transfer point of the folded product (5) from the folding blade cylinder (1) to the folding gripper cylinder (2), that the drivers (8) are positioned on the transport device (7) in such a manner that one driver at a time, after the insertion of the folded product (5) into the folding gripper (4) of the folding gripper cylinder (2) is inserted engagingly into the region (A) between the two halves (5a, 5b), which are still resting on the folding blade cylinder (1), and that after the release of the folded product (5) by the folding grippers (4), the drivers (8) transport the folded products (5) further after they have been removed from the folding gripper cylinder (2).
Claim 3
Dependent Claim
55 words
Device according to claim 1, characterized in that on either side of the folded products (5) that are to be accepted, one transport device (7) is provided, each of which includes an endless toothed belt or an endless chain, the deflecting wheel (10) of which is disposed in or above the wedge shaped region (A).
Claim 4
Dependent Claim
28 words
Device according to claim 1, characterized in that a folding product peeler device (13) is provided on the folding gripper cylinder (2), engaging below the jacket contour thereof.
Claim 5
Dependent Claim
34 words
Device according to claim 1 characterized in that the speed of revolution of the drivers (8) is lower than the circumferential speed of the folding blade cylinder (1) and the folding gripper cylinder (2).
Claim 6
Dependent Claim
38 words
Device according to claim 4, charcterized in that the speed of revolution of the drivers (8) is approximately 10 to 20% lower than the circumferential speed of the folding blade cylinder (1) and the folding gripper cylinder (2).
Claim 7
Dependent Claim
27 words
Device according to claim 1 characterized in that the revolving transport device (14) having the drivers (17) wraps partway around the folding gripper cylinder (2) (FIG. 3).
Claim 8
Dependent Claim
31 words
Device according to claim 1, characterized in that with an increasing movement component, the drivers (8) accept the folded products (5) from the folding gripper cylinder (2) and transport them further.
Claim 9
Dependent Claim
30 words
Device according to claim 1 characterized in that the revolving transport devices (25, 25', 28, 28') disposed on either side of the folded products (5) extend parallel to one another.
Claim 10
Dependent Claim
107 words
Device according to claim 1 characterized in that the revolving transport device (19, 19') disposed on either side of the folded products (5) extend obliquely to one another, in such a manner that the distance between them is least on either side of the region A and that on either side of the wedge shaped region (A) the drivers (20, 20' are inserted from the side between the halves (5a, 5b) by a control device (23, 23'), and that after a predetermined region, the drivers (20, 20') are retracted from the folded product (5, 5', 5") by the obliquely positioned revolving transport devices (19, 19') (FIG. 5).
Claim 11
Dependent Claim
49 words
Device according to claim 1, characterized in that in the wedge shaped region (A) the drivers (26, 26') are inserted from the side in between the halves (5a, 5b) of the folded product (5) by means of a control device (27, 27') for a predetermined travel distance (FIG. 6).
Claim 12
Dependent Claim
51 words
Device according to claim 1, characterized in that the drivers (30) in the wedge shaped region (A) are guided about a deflecting wheel (29) in such a manner that in the region A they are pivoted from below in between the halves (5a, 5b) of the folded products (5) (FIG. 8).
Claim 13
Dependent Claim
98 words
Device according to claim 1 characterized in that the drivers (35) are guided on a slide (36), which is guided in a left (41) and right (40) guide by a chain (34) about a deflecting wheel (47) in such a manner that the drivers (35), as the chain (34) is guided about the deflecting wheel (47), are inserted in approximately the same angular position (for instance, horizontal) laterally in the rising area of the guides (40, 41) for transfer of the folded products (5) in the area between the halves (5a, 5b) of the folded items (FIG. 10).
