Definitions

  • the invention relates to a folder for a Rotary press according to the preamble of claim 1 (see e.g. DE 35 40 062 A1).
  • EP 04 44 008 A1 describes a hard material coated circular knife.
  • EP 02 37 034 A1 discloses one-sided Cutting knife coated with hard material, with a Counter knife cooperates.
  • EP 03 27 530 A2 shows cutting knives with To coat metal nitride.
  • the invention is based on the object rotating cutter of a folder one To create web-fed rotary printing press.
  • Two cutting surfaces 2 beginning at the cutting edge 4; 3 run at an opening angle alpha ⁇ 90 °.
  • the cutting edge 4 can be continuous or have teeth 6 arranged next to one another.
  • the cutting knife 1 is made of metal, e.g. B. known Tool steel. Only one of the two cutting surfaces 2 or 3 extends from the cutting edge 4 over a Part of a width or over an entire width a as well over the entire length with hard material coating 7 between 0.5 ⁇ m and thicker, e.g. B. 15 microns coated. It is with respect to the width a of the hard material coating 7 too possible that the hard material coating only near the Cutting edge 4, d. H. approx. 0.5 mm from the cutting edge 4 starts away.
  • the hard material coating 7 consists of a material the group of metal carbides, nitrides, oxides, borides the silicides of the elements of the fourth to sixth Subgroup of the periodic table, individually or in Combinations used. This hard material coating will z. B. by means of PVD coating processes (physical vapor deposition).
  • the substances 8 are coated in one Thickness which is between 0.5 and 10 ⁇ m.
  • the metal e.g. B. the normal tool steel worked out as a result of wear, so that uncoated cutting surface 3 a cavity 9 receives a self-sharpening effect of the Cutting knife 1 enters.
  • it can also be analog a one-sided coating of an endless, d. H. annular cutting surface of a circular knife with the Hard material coating 7 or the substance mentioned 8 in its edge area.
  • Such circular knives will be used for slitting paper webs.
  • At the Installation of each circular knife must be ensured that a target wear side each z. B. with a hard or coated edge or surface of the circumferential cutting groove of a grooving roller cooperates to to bring about a self-sharpening effect.
