8. The apparatus in accordance with claim 1 , wherein the web length entering the loop store per time unit is controllable by an internal or external control device in dependence on the loop size.

9. The apparatus in accordance with claim 8 , wherein the removal device is controllable by the control device in dependence on the loop size.

10. The apparatus in accordance with claim 1 , wherein the removal device is controllable such that the web length entering the loop store per time unit is continuously variable in dependence on the loop size.

11. The apparatus in accordance with claim 4 , wherein the varying influence of the material loop on the suction device is provided as a measure for the loop size.

12. The apparatus in accordance with claim 1 , wherein the result of a position determination of the material loop is provided as a measure for the loop size.

13. An apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, the apparatus comprising:

a material store;

a removal device for a removal of a material web from the material store;

a loop store defining a space for the removed material web to form a loop, the loop store located between the material store and the cutting region;

wherein the loop store comprises a suction device for the material loop which acts on the material loop at least in a region at the outgoing side;

wherein the loop store comprises a blowing device for the material loop which acts on the material loop; and

wherein the suction device acts on an outer side of the material loop and the blowing device acts on an inner side of the material loop or vice versa.

14. The apparatus in accordance with claim 13 , the apparatus further comprising a fan having a suction side belonging to the suction device and a pressure side belonging to the blowing device.

15. The apparatus in accordance with claim 13 , wherein the suction device and the blowing device belong to a common air circuit.

16. The apparatus in accordance with claim 15 , wherein the common air circuit is controllable by an internal or external control device in dependence on the loop size.

17. An apparatus for a single-track or multitrack slicing of food products having a product feed which supplies products to be sliced on one track or on multiple tracks to a cutting region in which a cutting blade moves in a rotating and/or revolving manner to cut the supplied products into slices, and having an apparatus for the provision of web-like interleaved sheet material at the cutting region in which the products supplied are cut into said slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, said apparatus comprising:

a material store;

a removal device for a removal of a material web from the material store;

a loop store defining a space for the removed material web to form a loop, the loop store located between the material store and the cutting region, the loop store having a brake for the material web that actively increases the friction for the material web; and

wherein the loop store comprises a contact surface for at least one region of the material loop at the outgoing side of the loop, wherein the contact surface belongs to the brake for the material web.

18. The apparatus in accordance with claim 17 , wherein a common control device is provided which is configured to coordinate the slicing of the products and the provision of the interleaved sheet material.

19. An apparatus for a single-track or multitrack slicing of food products having a product feed which supplies products to be sliced on one track or on multiple tracks to a cutting region in which a cutting blade moves in a rotating and/or revolving manner to cut the supplied products into slices, and having an apparatus for the provision of web-like interleaved sheet material at the cutting region in which the products supplied are cut into said slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, said apparatus comprising:

a material store;

a removal device for a removal of a material web from the material store;

a loop store defining a space for the removed material web to form a loop, the loop store located between the material store and the cutting region;

wherein the loop store comprises a suction device for the material loop which acts on the material loop at least in a region at the outgoing side;
