Abstract

The invention relates to an apparatus for providing web-like interleaving sheet material on one track or on multiple tracks at a cutting zone in which products supplied on one track or multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone, having a removal device that is configured to remove the material web from a material store, and having a loop store in which the material web forms a loop having a loop portion at the incoming side and a loop portion at the outgoing side, wherein the loop store provides a reception space for the loop whose one side forms a support for the one loop portion and whose side opposite the support forms a boundary for the other loop portion.

First claim

The invention claimed is:

1. An apparatus for a single-track or multi-track providing of web-like interleaving sheet material at a cutting zone in which products supplied on one track or on multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone,
the apparatus having a removal device that is configured for a removal of the material web from a material store and having a loop store in which the material web forms a loop, the loop having a first loop portion at an incoming side of the loop store and a second loop portion at an outgoing side of the loop store,
wherein the loop store comprises a reception space for the loop whose one side forms a support for the one of the first loop portion and the second loop portion and whose side opposite the support forms a boundary for the respective other of the first loop portion and the second loop portion,
wherein the reception space is formed with multiple tracks.

2. The apparatus in accordance with claim 1 , wherein the reception space has an opening at least for the outlet of the second loop portion at the outgoing side and an end disposed lower than the opening; and wherein a plane extending through the opening and the end extends at an inclination with respect to the horizontal.

3. The apparatus in accordance with claim 1 , wherein the support provides a planar support surface for the one loop portion of the first loop portion and the second loop portion; and/or wherein the boundary provides a planar contact surface for the respective other loop portion of the first loop portion and the second loop portion.

4. The apparatus in accordance with claim 1 , wherein the support and the boundary extend at least approximately in parallel with one another in the longitudinal direction of the reception space.

5. The apparatus in accordance with claim 1 , wherein the spacing between the support and the boundary at a respective position in the longitudinal direction of the reception space defines a clearance of the reception space; and wherein the ratio between the smallest clearance of the reception space and the greatest clearance of the reception space is greater than 0.8.

6. The apparatus in accordance with claim 1 , wherein the spacing between the support and the boundary at a respective position in the longitudinal direction of the reception space defines a clearance of the reception space; and wherein the ratio between the greatest clearance of the reception space and the length of the reception space effective for the loop formation amounts to less than 0.5 or less than 0.3 or less than 0.1.

7. The apparatus in accordance with claim 1 , wherein the reception space is closed at at least one side.

8. The apparatus in accordance with claim 1 , wherein the reception space has a suction zone for the loop that communicates with a vacuum source to act on an outer side of the loop in the sense of a loop size increase.

9. The apparatus in accordance with claim 8 , wherein one or more suction apertures opening into the suction zone are provided in least one side of the reception space, via which suction apertures the vacuum source communicates with the suction zone.

10. The apparatus in accordance with claim 1 , wherein a braking apparatus for the material web is integrated into the loop store.

11. The apparatus in accordance with claim 10 , wherein the braking apparatus comprises a surface of the reception space at the outgoing side.

12. The apparatus in accordance with claim 1 , wherein the surface at the outgoing side is formed as air permeable.

13. The apparatus in accordance with claim 12 , wherein the surface at the outgoing side communicates with a vacuum source.

14. The apparatus in accordance with claim 1 , wherein the loop store comprises a device for determining a measure for the size of the loop in the loop store.

15. The apparatus in accordance with claim 14 , wherein the device comprises at least one sensor that acts at a surface of the reception space at the outgoing side or at the incoming side.

16. An apparatus for the single-track or multi-track slicing of food products, the apparatus comprising:
a product feed that supplies products to be sliced on one track or on multiple tracks to a cutting zone in which a cutting blade moves in a rotating and/or revolving manner to cut the supplied products into slices; and
an apparatus for providing web-like interleaving sheet material for a single-track or multi-track providing of web-like interleaving sheet material at a cutting zone in which products supplied on one track or on multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone, the apparatus having a removal device that is configured for a removal of the material web from a material store and having a loop store in which the material web forms a loop, the loop having a first loop portion at an incoming side of the loop store and a second loop portion at an outgoing side of the loop store,
wherein the loop store comprises a reception space for the loop whose one side forms a support for one of the first loop portion and the second loop portion and whose side opposite the support forms a boundary for the respective other of the first loop portion,
wherein the reception space is formed with multiple tracks.

17. An apparatus for a single-track or multi-track providing of web-like interleaving sheet material at a cutting zone in which products supplied on one track or on multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone,
the apparatus having a removal device that is configured for a removal of the material web from a material store and having a loop store in which the material web forms a loop,
the loop having a first loop portion at an incoming side of the loop store and a second loop portion at an outgoing side of the loop store,
wherein the loop store comprises a reception space for the loop whose one side forms a support for one of the first loop portion and the second loop portion and whose side opposite the support forms a boundary for the respective other of the first loop portion and the second loop portion,
wherein the reception space is formed with multiple tracks,
wherein the reception space includes at least one dividing member extending in the longitudinal direction of the reception space to separate loops of material webs introduced on multiple tracks from one another, and
wherein the at least one dividing member is adjustable in the transverse direction.

18. An apparatus for a single-track or multi-track providing of web-like interleaving sheet material at a cutting zone in which products supplied on one track or on multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone,
the apparatus having a removal device that is configured for a removal of the material web from a material store and having a loop store in which the material web forms a loop,
the loop having a first loop portion at an incoming side of the loop store and a second loop portion at an outgoing side of the loop store,
wherein the loop store comprises a reception space for the loop whose one side forms a support for one of the first loop portion and the second loop portion and whose side opposite the support forms a boundary for
