These cams 11a, 11b, 12a, 12b are arranged, for example, in pairs of cams, with the pair of cams 11 being assigned the cams 11a, 11b and the pair of cams 12 being assigned the cams 12a, 12b, for example.
- the exemplary cams 11a, 11b, 12a, 12b or the pairs of cams 11, 12 can be positioned below the rotating vacuum transfer cylinder 2.
- the exemplary control curves 11a, 11b, 12a, 12b, or the control curve pairs 11, 12, can themselves be movable and optionally moved/displaced into a position on/along the pitch circles 14, 15.
- control cam 12a can be moved from a position on inner pitch circle 15 to a position that is further inside than the radius of inner pitch circle 15, and control cam 12b can be moved from a position on outer pitch circle 14 to a position that is further outside than the radius of the Outer pitch circle 14.
- the cams 11a, 11b, 12a, 12b or cam pairs 11, 12 can be assigned to different work areas 22, 23.
- the cams 11a, 11b of the pair of cams 11 are assigned, for example, to the work area 22 for transferring labels to the containers (not shown) on turntables 8a of the conveyor 8, and the cams 12a, 12b of the pair of cams 12 are assigned, for example, to the work area 23 of the Gluing device 3 assigned.
- cams 11a, 11b, 12a, 12b of a pair of cams 11, 12 can be opposite one another on different pitch circles 14, 15 and each lie in a common plane.
- the cam pairs 11, 12 it is possible, among other things, for the cam pairs 11, 12 to be on different planes.
- the pair of cams 12 assigned to the working area of the gluing device 3 can be on a different level than the pair of cams 11 assigned to the working area 22 for transferring the labels to the containers.
- An example bar control for controlling / switching the movement of the vacuum suction bars can therefore include at least one control cam, e.g. control cams 11a, 11b, 12a, 12b, which, in cooperation with at least one control roller of a vacuum suction bar, controls the movement of the respective vacuum suction bar, e.g. 16a, 16b, 16c , 17a, 17b, 17c, 18a, 18b, 18c, 19a, 19b, 19c, 20a, 20b, 20c, 21a, 21b, or 21c, can control or switch.

- the vacuum suction strips of the strip groups 16, 17, 18, 19, 20, 21 are alternately assigned control curves on different pitch circles.
- This assignment is only an example and can be changed, for example, by the fact that the control rollers of the vacuum suction strips of the strip groups can be switched / reconfigured in order to be able to interact with a control cam on a different pitch circle, so that, for example, the strip group 16 can also be controlled by a control curve / control cams on the outer pitch circle 14 can be switched instead of by a control cam / control cams on the inner pitch circle 15.
- a strip group can include only two vacuum suction strips, for example only a starting suction strip and an end suction strip, ie a central suction strip can be dispensed with, for example.
- the vacuum suction rails can each be connected between an outer working position and an inner working position, with the radial distance of a vacuum suction rail from the longitudinal axis or axis of rotation 13 of the vacuum transfer cylinder 2 in the outer working position being greater than the the radial distance of a vacuum suction bar to the longitudinal axis or axis of rotation 3 of the vacuum transfer cylinder 2 in the inner working position.

- the control cams 12a, 12b in the working area 23 can be moved out of the path of the control rollers or switched off, i.e. the control rollers run past the control cams 12a, 12b without making contact, or the control cams 12a, 12b can be in the path of the control rollers, i.e. so be positioned/connected to pitch circles 14 or 15.
- the end squeegee and the center squeegee are either controlled or switched by the inner pitch circle cam 12a or the outer pitch circle cam 12b.
- Case 1 The slat group located in the work area 22 is occupied / equipped with a label o
- the initial squeegee of the slat group located in the work area 22 is and remains in the outer working position, since its control roller is on a different level than the plane in which the cams 11a, 11b are located.
- Case 2 The bar group located in work area 22 is not occupied / equipped with a label o No difference to case 1.
- the vacuum bars of the bar group located in work area 22 are switched as in case 1.
- the arrangement and position of the control cams 11a, 11b can remain unchanged.
