  • the Fig. 2a and 2 B show as well as the Fig. 1a . b and c temporally successive operating positions of the device, and it is from the Fig. 2a . b it can be seen that the process of folding over a product 13 with a roller conveyor 17 can be achieved in the same way as with a belt conveyor according to FIGS Fig. 1 a, b and c, since the required acceleration forces can be applied to the product by means of the illustrated roller conveyor 17.
  • an additional roller conveyor 9 ' is provided, which supports the folding process.
  • Fig. 3 shows two roller conveyors 17, 9 'as a folding means.
  • the folding means 17, 9 ' are respectively driven and rotate in the directions of rotation D, D'.
  • the disc 13, which reaches the roller conveyor 17, thus experiences a pulse, so that a folding process is initiated.
  • the disc hits the roller conveyor 9 ', which is arranged below the roller conveyor 17 and is offset in the removal direction T to the front.
  • the disc 13 undergoes an additional impulse and is folded further.
  • the direction of rotation D 'of the roller 9' can also be opposite, so that a folded disc 14, which is located on the Portionierband 6, even during transport in Abtransportraum T folded further or not deployed.
  • the roller conveyor 9 ' is arranged at a distance from the portioning belt 6, which is smaller than the height of the folded disc 14. The disc 14 is thus pressed down and prevented from unfolding. In principle, however, the roller conveyor 9 'can also be arranged at a distance which is greater than that Height of the folded disc 14. The disc 14 can be transported unhindered in this case.
  • the portioning belt 6 is inclined relative to the horizontal by an angle ⁇ , which is approximately 20 °. Accordingly, the portioning belt 6 runs obliquely downwards. This promotes especially the folding process.
  • the control band 7 however, inclined obliquely upward by an angle ⁇ .
  • the angle ⁇ is about 12 °.
  • Fig. 4 two folded discs 14 are shown. Shown here are the fold length I, the slice thickness h and the force F. These factors in particular affect the deflection s.
  • the folded discs 14 overlap one another.
  • the weight of the overhead disc 14 prevents this, that the underlying disc 14 unfolds again.
  • Fig. 5 shows three roller conveyors 17, 17 ', 9' as a folding means.
  • the folding means 17, 17 ', 9' are each driven and rotate in the rotational directions D, D ', D ".
  • the distance between the two folding means 17, 17' is smaller than the extent of the disk 13.
  • the folding means 17, 17 ' form - figuratively speaking - a sort of gate, which has to pass through the disc 13. As it passes through, the disc 13 experiences a pulse at both ends by the oppositely rotating folding means 17, 17 ', so that a folding process is initiated folded folded on the Portionierband 6.
  • a further folding means 9 ' is provided to support the folding process or the removal.
  • the embodiment according to Fig. 6 corresponds substantially to the embodiment according to Fig. 5 , wherein instead of the roller conveyors 17, 17 ', two belt conveyors 8, 8' are provided. These folding means 8, 8 'transmitted to the two ends of the disc 13 a pulse, whereby the disc 13 is folded.
  • Fig. 7 shows a slicing device according to the invention, which comprises a trained as an X-ray scanner 18 detection device.
  • the X-ray scanner 18 records product-specific data, such as the density of the product 3.
  • product-specific data such as the density of the product 3.
  • the product 3 is cheese, in particular the distribution of the holes can be determined.
  • the determined data are forwarded to a control device 19. From the data, for example, a specific slice thickness is determined, which, in compliance with any additional conditions such. the weight of a portion having an optimum folding property.
  • the control device 19 controls the feed device 4, the circular blade 2, the roller conveyor 17 and / or the Portionierband 6 accordingly.
  • the slice 13 can be thicker.
  • the cheese can be pushed by the feed device 4 at a relatively low speed on the circular blade.
  • the leg length of the upper half of the disk can be made longer. This is particularly advantageous in disc shapes, in where the width in the folding area is greater than at the end, such as in round discs.
  • a displaceably arranged roller conveyor 17 is shown. This can be aligned according to a central axis MA of the product 3.
  • the orientation of the roller conveyor 17 can in particular be based on empirical values already stored or else on the basis of product-specific data.
  • the position of the roller conveyor 17 can also be changed or at least readjusted during the slicing process.
  • the roller conveyor 17 is thus always in an ideal folding position.
  • the position of the roller conveyor 17 can be changed during the folding operation by means of a control device. In this way, the movable roller conveyor 17 can support the folding process.
  • a product 3 can be divided into several areas A, M, E using product-specific data, in this case the contour.
