Clip supply

1. A supply of suspension elements being fed in a feeding direction to a clipping machine for producing sausage-shaped products and being attached to said sausage-shaped products, the supply comprises:

a carrier strip having at least an upper and a lower surface and two longitudinally extending edges arranged parallel to each other, and

a plurality of suspension elements attached to the upper or lower surface of the carrier strip in at least substantially regular intervals, wherein the carrier strip, including the suspension elements, is wound, thereby forming a roll, and having at least one mark which is attached to the carrier strip at a predefined distance from an end of the carrier strip.

2. The supply according to claim 1 , wherein the at least one mark includes information regarding a number of suspension elements remaining on the carrier strip in the feeding direction upstream of said mark.

3. The supply according to claim 2 , wherein the information included in the at least one mark is used for controlling the clipping machine.

4. The supply according to claim 1 , wherein the at least one mark is a machine readable label.

5. The supply according to claim 4 , wherein the at least one mark is a RFID label.

6. The supply according to claim 1 , wherein the at least one mark is covered by a covering element.

7. The supply according to claim 1 , wherein the carrier strip of the supply is a double layer strip having an upper and a lower layer, with the upper and lower layer each having an upper and a lower surface and with the lower layer facing the lower surface of the upper layer with its upper surface, with the suspension elements disposed between the upper and lower layer in at least substantially regular intervals, and wherein the at least one mark is also disposed between the upper and lower layer at the predefined distance from an end of the carrier strip.

8. The supply according to claim 1 , wherein the clipping machine comprises a sensor device for detecting the at least one mark which is attached to the carrier strip of the supply, and for reading information stored on the at least one mark.

9. The supply according to claim 1 , wherein the suspension elements comprise suspension loops.

10. The supply according to claim 1 , wherein the sausage-shaped products comprise sausages.

11. A method for detecting an end of a supply of suspension elements fed in a feeding direction to a clipping machine for producing sausage-shaped products and being attached to said sausage-shaped products, the method comprises the steps of:

feeding suspension elements, which are attached to an upper or lower surface of a carrier strip in at least substantially regular intervals, to the clipping machine for attaching said suspension elements to the sausage-shaped products, and

scanning the carrier strip and detecting at least one mark positioned on the carrier strip at a predefined distance from an end of the carrier strip.

12. The method according to claim 11 , further including the step of reading the information stored on the at least one mark.

13. The method according to claim 12 , further including the step providing a signal to the clipping machine for controlling the clipping machine on the basis of the information readout of the at least one mark.

14. The method according to claim 12 , further including the step of outputting a signal corresponding to the information readout of the at least one mark.

15. The method according to claim 11 , wherein the at least one mark has information regarding a number of suspension elements remaining on the carrier strip in the feeding direction upstream of the mark.

16. The method according to claim 11 , wherein the suspension elements comprise suspension loops.

17. The method according to claim 11 , wherein the sausage-shaped products comprise sausages.
