[0028] FIG. 1 shows a slicing device 5. The slicing device 5 has a cutter blade 11 which cuts a foodstuff product 2 into foodstuff slices 12. To this and, each foodstuff product 2 by way of a conveying means 4, presently two conveyor belts 4, is continuously or intermittently transported in the direction of the cutting plane 6 of the blade 11. The lower conveyor belt 4 is simultaneously a product support. The cutter blade 11 is fastened to a rotating blade receptacle 3 and in a cutting manner interacts with a cutting edge 9 which is provided at the front end of a product support 4, for example, together with the latter defining the cutting plane 6. A so-called cutting gap which is to be as small as possible but has to be sufficiently large for the blade not to contact the cutting edge is present between the blade 11 and the cutting edge 9. This gap has to be regularly set. This may be performed by moving the blade and/or the cutting edge. Moreover, the cutting edge must be aligned so as to be parallel with the blade. After slicing, the foodstuff slices typically drop onto a placing table 1 which is provided with transportation means, for example a transportation belt or transportation tapes, on which said foodstuff slices are configured so as to form a respective portion 14, presently a stack. The completed portions 14 are then transported away from the region of the cutter blade and then packed. A sheet-metal underlay tray which in particular prevents excessive elongation of the transportation means may be provided below the transportation means of the placing table. The slice thickness is then a result of the indexing path of the foodstuff product between two cuts. In the case of a constant rotating speed of the blade, regulating the slice thickness is performed by way of the indexing speed of the foodstuff product. The slicing device may have one gripper 8 per indexing lane, which gripper 8 grips the rearward end 13 of the foodstuff product 2 prior to or during slicing, stabilizing the latter during slicing, in particular toward the end of slicing, and disposing of the end piece that cannot be sliced. Each gripper is preferably provided on a gripper carriage (not illustrated) which moves the grippers to and fro, in particular in parallel with the indexing direction of the foodstuff product.
[0029] The slicing device is preferably provided having multiple tracks, i.e. so that a plurality of foodstuff products 2 are in particular at least in part simultaneously, or at least in part sequentially, sliced by one blade. To this end, the device for each foodstuff product has a dedicated track 7 along which said foodstuff product is transported in the direction of the blade 11.

In the present case, the cutting strip has an interleaver exit duct 15 from which an interleaver strip exits, said interleaver strip being likewise severed by the cutter blade from the interleaver strip and being provided between two foodstuff slices such that the adhesion between the foodstuff slices is reduced. According to the invention, this cutting strip is now manufactured according to the rapid-manufacturing method, or by way of a layered construction, respectively. On account thereof, the interleaver exit duct in particular may have a shape which has not been possible by casting, injection-molding, or a subtractive machining method. The cutting strip is preferably manufactured from a plastics, metal, and/or ceramics material. These materials are preferably applied as a powder and thereafter connected to the material layer therebelow. It has been surprising to a person skilled in the art that, despite a comparatively porous construction of the material, the hygiene required for a foodstuff-processing device is existent.
[0031] FIG. 3 shows a further preferred embodiment of the present invention. In the present case, that part that has been manufactured according to a rapid-manufacturing method, or by way of a layered construction, respectively, is the product gripper 8 which is made to connect to the rear end, i.e. that end that faces away from the cutting face, of the foodstuff product 2. In particular, the gripping tongs 16 which are driven into the product as soon as the gripper bears on the rear side of the foodstuff product are manufactured according to the rapid-manufacturing method, or by way of a layered construction, respectively. On account thereof, very complex structures of the gripping tongs, which improve contact between the gripper and the foodstuff product, may be implemented, on account of which the latter in terms of the position thereof may be better stabilized in particular when slicing of the foodstuff products is close to being terminated. Alternatively or additionally, according to a further preferred embodiment of the example, the contact face of the gripper for the foodstuff product is manufactured according to the rapid-manufacturing method, or by way of a layered construction, respectively. On account thereof, contact faces which are individualized for the respective foodstuff product may be manufactured, without expensive tools, in particular casting tools, having to be manufactured. Preferably, the gripper, the gripping tongs and/or the contact face is/are manufactured from a plastics, metal, and/or ceramics material.
