    25 30 535 B38 In case a removable cutting knife is used, it is attached adjacent to this opening at one of the surfaces which form the trench-shaped section. This means that the knife forms a certain smaller angle to the plane of the cutting disc. The angle can be typically 10 - 20 degrees.
    In the case of cutting discs of this type, but which are intended for shredding foodstuffs, such as vegetables, it is previously known that between the front part of the knife with the edge of the knife, which is at a distance from the plane of the cutting disc and the plane of the cutting disc, there is a shredding means number of adjacent knives, which run perpendicular to the plane of the cutting disc. In use, the former knife cuts a slice of the vegetable, which slice is shredded longitudinally by the latter knives, after which the strips are lowered under the slice.
    The fact that the knife forms a certain smaller angle to the plane of the cutting disc means that it is not possible to cut thin slices of certain vegetables, which are then shredded, without the strips becoming deformed and the strips becoming differently thick, which is an unacceptable cutting result.
    The present invention solves this problem.
    The present invention thus relates to a cutting disc for shredding foodstuffs for use in a cutting machine, which cutting disc comprises a centrally arranged, through-hole and an opening extending in radial direction, which cutting disc is made of sheet metal and which disc comprises a peripheral arranged around the disc, first bent edge and a second bent edge arranged circumferentially around the through hole, the disc comprising a ditch-shaped section with a sloping part extending radially from the center of the cutting disc and out to said first bent edge and wherein a fastening means for attaching a cutting means comprising a first knife is arranged along the sloping part and where fastening means are arranged for fastening a shredding means comprising a number of knives and is characterized in that the first knife is bent along a bending line running in the longitudinal direction of the knife, because the fastening means of the knife are present in a portion of the knife on one side of the bending line and in that said edge is present running along the free edge of the first knife in a portion of the first knife on the other side of the bending line and in that the bending angle between the portions is such that the portion of the knife is present parallel to the plane of the cutting disc, when the knife is mounted on the cutting disc and in that the knives of the shredding member arranged in parallel run perpendicular or substantially perpendicular to the edge of the first knife in said opening at the part of the first knife where the edge is present .
    The invention will be described in detail below, with reference to exemplary embodiments of the invention and the accompanying drawings, in which - figure 1 is a perspective view of a cutting disc according to the invention - figure 2 shows a shredding member, which in figure 1 is mounted Figure 4 is a plan view of a cutting disc knife according to the invention - Figure 4 is a simplified plan of a knife according to Figure 3 - Figure 5 is a side view of a knife according to the invention.
    Figure 1 shows a cutting disc 1 according to Swedish patent 531 916, intended for use in a cutting machine. The disc 1 is substantially flat and is associated with an axial direction A, an angular direction V and a radial direction R.
    The disc 1 comprises a peripheral edge 2 extending in the angular direction V around the axis 1 of the disc 1 and a centrally arranged, through hole 3. The dimensions and shape of the hole 3 are adapted to be able to engage in the existing attachment for a cutting disc of a known cutting machine (not shown), in which the cutting disc 1 is intended for use.
    The disc 1 further comprises a radially elongated, ditch-shaped section 5, 9 extending in the radial direction R, out from the haul 3, which may, for example, have parallel edges or be substantially radially symmetrical. The ditch-shaped section comprises a sloping part 5. Next to the sloping part 5 there is arranged an opening 6, which extends substantially in the radial direction R and through which cut-off food is passed when using the cutting machine.
    Along a free edge of the opening 6 there is a cutting edge arranged to support a replaceable cutting member in the form of a first blade-shaped knife 10. The knife is arranged to be mounted on the cutting disc 1 by means of conventional fastening means 4, for example in the form of internally threaded holes, which are arranged to be able to engage in externally threaded screws, which in turn are arranged to be able to retain the cutting member on the sloping part 5, along a free edge of the sloping part 5.
    The sloping part 5 comprises at least one surface section which slopes along the angular joint V of the disc 1 so that a point on the sloping surface section which is further away from the cutting edge in the angular direction V is also further away from the main plane of the disc 1 in the axial direction A 10 15 20 25 535 B38 When used in a cutting machine, the disc rotates in the angular direction V, preferably at a speed between 100 and 3000 revolutions per minute. Foods to be decomposed, meat, such as vegetables, etc., are fed in the axial direction A in the direction of the disc 1. Due to the rotation of the disc 1, the foods are pressed against the cutting edge and cut by it. The cut-off food parts are further pressed, due to the rotation of the disc 1 in combination with the sloping plane of the sloping part 5, through the opening 6 away from the disc 1 in the axial direction A and further towards the collecting or discharging device of the cutting machine or a subsequent processing step. .
    Food thus passes through the opening 6 in connection with them being cut apart by the cutting edge. The opening 6 can be arranged with different heights and widths, depending on the purpose of the cutting disc 1.
    Conventional cutting discs are usually made of cast light metal. The present cutting disc 1 is made of relatively thin stainless steel, between 1 and 2.5 millimeters thick, preferably about 1.5 mm.
    The above is stated in the above-mentioned Swedish patent.
    A fastening means 4 for fastening a cutting means comprising a first knife 10 is arranged along the sloping part 5. Furthermore, fastening means 18, 19 are provided for fastening a shredding means 14 comprising a number of knives 11 arranged in parallel.
    As a result, the first knife will cut food which is fed towards the knife by the cutting disc rotating and immediately thereafter the knives 11 of the shredding means 14 will divide the cut food into parallel strips. The strips will then pass through the opening 6.
    According to the invention, the first knife 10 is bent along a bending line 13 running in the longitudinal direction of the knife. The fastening means 4 of the first knife 10 are located in a portion 15 of the knife on one side of the bending line 13. Said edge 12 is present running along the free edge of the first knife in a portion 17 of the first knife on the other side of the bending line 13. the angle of inclination between the portions is such that the portion 17 of the knife, where the edge 12 is located, is parallel to the plane of the cutting disc 1, when the knife 10 is mounted on the cutting disc 1.
    According to the invention, the knives of the shredding member arranged in parallel run perpendicular to the edge of the first knife in said opening at the portion of the first knife where the edge is present.
    Thus, by this design of the knife, the portion 17 of the knife where the edge is located will be parallel to the upper surface of the cutting disc. As a result, a vegetable which is cut will abut against the portion 17 during the cutting, which thereby forms a support for the vegetable, which is pressed down from above against the cutting disc by a feeding device.
    The parallel knives of the shredding means are arranged perpendicularly or substantially perpendicular to the portion 17 of the first knife, where its edge 12 is located.
    Due to the described design of the first knife and the shredding member 14, strips are cut with a square or rectangular cross-section or with a constant thickness according to their length. Furthermore, the strips can be made thin.
    It is preferred that said portions 15, 17 of the knife on both sides of the bending line 11 are flat.
    It is further preferred that the knife 10 be made of stainless steel.
    According to a preferred embodiment, the knife 10 is arranged to abut against and be attached to the underside of the sloping part 5.
    According to another preferred embodiment, the edge 16 of the knife 10 is ground so that the grinding is only present on the underside 21 of the knife 11 when the knife is mounted on the cutting disc.
    Preferred embodiments have been described above. However, it will be apparent to those skilled in the art that many changes may be made to the described embodiments without departing from the spirit of the invention. Thus, the invention should not be limited by the described embodiments, but may be varied within the scope of the appended claims.
