Definitions

  • the invention relates to a method for slitting materials in continuous web form, such as aluminum'or the like, by means of axially parallel pairs of circular knives which excise a narrow strip of waste, and additionally the invention relates to an apparatus for the practice of this method.
  • paper and cardboard slitting apparatus is being used also for cutting aluminum sheets and bands, because the cutting conditions involved, such as thickness of the material, cutting angles and knife arrangement are comparable.
  • the invention is addressed to the problem of controlling the circular knives such that, after the dividing cut, a sufficiently great distance will be left between the knives and the cut edges.
  • FIG. 1 shows the slitting machine looking upstream
  • FIG. 2 is a side elevational view of the slitting system seen from the left of FIG. 1;
  • FIG. 3 is a horizontal cross section taken through the upper pair of slitting knives with shaft 3 omitted.
  • the slitting system represented in FIGS. 1 to 3 for the slitting of the aluminum web 1 consists of two upper circular knives 4 and 5 disposed by means of a clamping boss 2 on the upper knife shaft 3, the cutting edges 7 and 8 of the said knives being urged by a rubber ring 6 against thecutting edges 9 and 10, respectively, of the bottom cutting rings 1 l and 12.
  • These bottom cutting rings 11 and 12, which with the adjacent sleeves l3 and 14, respectively, are mounted on the bottom cutter shaft 15 and form a virtually closed cylindrical roll, are held at an invariable distance from one another by a spacer ring 16.
  • the preservation of this quality is achieved by the provision of the pressure wheels 24 and 25 which are held by the wheel forks 28 and 29 and urged against the outer sides 30 and 31 of the upper circular knives 4 and 5 by the cup spring sets 26 and 27 supported by mounting means which are not shown.
  • the pressure of the cup spring sets 26 and 27 may be adjusted by means of adjusting means which are not shown, so that the cutting edges 7 and 8 of circular knives4 and 5, respectively, will undergo a slight, transient deformation in back'of the cutting point S and form a constantly increasing clearance between themselves and the cutting edges 9 and 10 of the bottom cutting rings 11 and 12 corresponding to a relief angle. Through this deformation the contact that spoils the cut edges 19 and 20 of product webs l7 and 18, respectively, is prevented by the cutting edges 7 and 8 of circular knives 4 and 5, respectively, emerging from the overlap area 32 (FIG. 2).
  • each of said bearing means comprises a rolling pressure member.
  • said rolling pressure member comprises a rotatable wheel contacting its circular knife at said portion of its periphery, the plane of said wheel making an acute angle with the axis of its circular knife, and means resiliently urging said wheel into contact with its circular knife.
  • An apparatus including means for independently adjusting the urging of each wheel against its respective circular knife.
