- the invention provides that the device for supplying negative pressure can be mounted in the circumferential direction so as to be displaceable about the central axis 16 in directions a and b.
- the device 8 By moving the device 8 in the direction a, at least along parts of the area A, it is achieved in particular that suction within a transport cycle begins earlier, so that the required negative pressure for suctioning a piece of hose 10 is also reached earlier.
- a displacement of the slidably mountable device 8 in the direction a is thus provided in particular at higher transport speeds.
- the displaceably mountable device 8 can be displaced in direction b, at least along parts of surface B. Due to the slower transport speed, a shorter path is sufficient to achieve the necessary negative pressure for the suction of a piece of hose 10. Here it is more important to ensure that the negative pressure does not break in too early, so that a hose is released during the transport process before it reaches a discharge device 14. This would result in compression of a hose 10 within the system, which can lead to a complete system failure.

- the detection unit 54, the processing unit 56 and the control unit 58 can be arranged in particular within the device 8.
- the individual system components can also communicate wirelessly or contactlessly with one another via Bluetooth, WLAN, NFC, Zigbee or the like and accordingly cannot be connected to one another via a communication and control line 59.
- a change in the transport speed of the present system can be recognized in a simple manner, whereupon the desired position of the device 8 can be adapted accordingly in order to both secure takeover and secure transfer of hose pieces 10 to ensure.
- the aforementioned system components of a detection unit 54, a processing unit 56 and a control unit 58 can also be arranged remotely from the device 8 and preferably integrated into a control unit or the like.

- This position is advantageously provided for high transport speeds, so that an earlier evacuation (in relation to the orientation according to FIG. 3) ensures the suppression required for hose transfer despite the high transport speed.
- a detection unit 54, a processing unit 56 and a control unit 58 can also be provided to automate an adaptation of the position of the device 8 to a transport speed, as is not explicitly shown here.

- Such an arrangement is particularly suitable for slow transport speeds, since evacuation is not critical here due to the low transport speed. However, this arrangement ensures that the hose section 10 in question can still be safely transferred to the discharge unit 14 even at a low transport speed.
- a detection unit 54 (not shown here), a processing unit 56 and a control unit 58 can also be provided here with regard to an automated adaptation of the positioning of the device 8 to the transport speed.
- the device 8 is formed in several parts and comprises a first part 8a and a second part 8b separated therefrom by a web-like intermediate element 49.
- the two parts 8a and 8b can be moved independently of one another along the directions a and b within the surfaces A and B in the circumferential direction to the central axis 16. In this way, a particularly precisely adjustable supply of the suction devices 6 with negative pressure can take place, so that a suction point for a supply process can be set independently of a delivery point for a discharge process.
