Definitions

  • the invention relates to a cutting knife for rotary cutting systems for paper, in particular multilayer paper products according to the preamble of claim 1.
  • round knives and corresponding counter knives are usually used for cutting paper products, for example in the form of flakes.
  • those with radial projections or with saw teeth are also known. All cutting knives of this type can be resharpened in the cutting surface or in the cutting surfaces, which, however, has the main consequence that the diameter of the cutting surface is reduced.
  • these known cutting knives have not been particularly successful because their service life is relatively short.
  • the invention has for its object to increase the life of cutting knives of the type mentioned and at the same time to ensure that the effective radius of the cutting surfaces can remain unchanged even after any regrinding.
  • the radius of the grinding surface remains unchanged even after any regrinding.
  • the blades are rectangular in longitudinal section and form the cutting surface in tooth form.
  • the blades preferably form an angle of 10-22 °, preferably 16 °, with the cutting plane.
  • a prerequisite for such displaceability of the individual blades is a truncated cone-like design of the base body, shoulder surfaces can optionally be provided in the base body in order to support the respective blades in their starting position backwards.
  • the blades are slidably mounted in elongated recesses of the base body.
  • the Longitudinal axes of the blades make an acute angle to the respective radius of the base body; this angle can be 9-12 °, preferably 9 °.
  • the blades are expediently approx. 3-5 mm, preferably 4 mm, thick.
  • the elongated recesses receiving the blades can also be offset in parallel by approximately 25-31 mm, preferably 28 mm, with respect to a radius assigned to them.
  • the blades are preferably held in the elongated recesses by two screw bolts.
  • the blades consist of a specially hardened steel which differs from the base body. In this way it is possible to extend the life of the cutting knife particularly well, the base body being able to be used even when the blades are completely replaced.
  • a cutting knife 1 with a diameter 2 of approximately 32 cm is, as can be seen from FIG. 2, frustoconical, the surface 3 enclosing an angle 5 of 16 ° with respect to the cutting plane 4.
  • the central, ring-shaped region of the base body 6 has a likewise conical outer edge surface 7 which, however, as can be seen in particular from FIG. 2, has recesses 9 in the region of the respective blades 8.
  • the base body 6 consists of a material customary for cutting knives; in contrast, the blades 8 are made with a thickness of 4 mm from a specially hardened steel.
  • the blades 8 have a rectangular cross-section in plan view, at least with respect to their cutting surface 10, while they can be rounded at their end 11 pointing towards the center.
  • the blades 8 each have a longitudinal slot 12, which - as described in more detail below - serves to receive screw bolts.
  • an inclined position of the blades 8 (see FIG. 1) also has a special shape with respect to the respective radius reached the cutting surface, which in this case resembles a tooth shape.
  • the associated blade 8 ' is offset by 28 mm in the illustrated embodiment. This dimension is provided with the reference number 16.
  • 40 blades 8 are provided, so that the center of the intersection of two adjacent blades is each around dimension 17, i.e. 9 °, spaced.
  • the blades are mounted displaceably in recesses 18, not shown, in the base body, two screw bolts 19 and 20 each holding the blades in the operative position and ensuring their displaceability.
  • This cutting knife can be used as a single knife or especially in rotary cutting systems for multi-layer paper products e.g. in scale form can be used together with a corresponding counter knife.
  • This counter knife which is usually designed as a lower knife, cooperates in the cutting plane 4 with the cutting edge 13 of the individual blades.
