Definitions

  • the present invention has for its object to overcome the above-mentioned drawbacks.
  • the invention is substantially distinguished by the fact that the paper is brought ,into contact with ,a patrix, the relief-like portions of which have end surfaces corresponding to the shape of the perforation holes, whereupon.the' portions ofthe paper bearing on said end surfaces are .worked offlby means of one or more chip removing tools, while .the
  • the patrix preferably takes the foriniof a rotating roll, the paper. web being entrained round. the roll in a position bearing on its relief-like portions and being worked upon by means of one or more stationary arranged rotating'tools preferably consisting of cutters orrotating knives-with the cutting ,edgesjdisp'osedobliquely to the axis of rotation.
  • The, working'oif of the paper material may also be effected by a scrapingor grinding action, for instance by means of a grinding roll.
  • any tool may be used by' means of which paper mater'ial may be removed in the form of chips or-th'e like.
  • the patrix roll and the tool' should preferably rotate in opposite directions, so that the paper and the cutting edges acting upon the same move in the same direction, "the tool then rotating at a speed which is a multiplicity of the speed of thepatrix roll.
  • the relief-like portionssupportf ingthe paper are preferably shaped in the'forrn' of' studs or pins arranged on the cylindrical surface of the rolland having end surfaces corresponding.to the shape of' the 4 2,908,201 Patented Oct. l3, 1959 paper web, saidstudsbr pins havingend surfaces corresponding to the shape of the perforation holes; I "The studs have a height above the cylindrical surface-of theroll which is only slightly, for instance 1.1 mm.
  • the studs have a conical, outwardly tapering formif"
  • the paper will then rest in part on the ends of said studs or pins and in part on portions of thelcylindrical surface of thepatrix rolllocated between the studs.
  • the roll rotates in-the direction indicated by the arrow 7 and entrains the paper web 2 during its rotation.
  • the paper web first meets w ith 'a cylindrical cutter 8 with screw-shaped cutting edges or knives 9, Fig. 4, intended to work upon the'portions of the paper web bearing on'said studs6.
  • the cutter 8 rotates in the direction shown by the arrow '10 at a peripheral speed which is many times greater than that of the patrix roll 4, the peripheral portions of the cutter and the roll running in the same direction.
  • the distance between the cuttingedges of the cutter and .the peripheral surfaces llof the studs is chosen so. that the knivespenetrat'e into the paper for approximately ninetenths of the thickness of the'paper. :An arrangement for accurate adjustment'of the cutter relatively to the peripheral surface of thestudswill be described in the following with reference to Fig. 5.
  • the end surface 11 of the studs 6 facing thecutter is located in a cylindrical'surface coaxial with the'axis' of the patn'x roll.
  • the endsurface 11 is providedwitha dished cavity limited-by anfannular edge portion 13 ofsaid surface.
  • the cutting 'edges 9 first means with the paper web, this takes placeat the left side of the stud 6 (Fig. 2), said cutting edge then cutting down i into the paper and reaching its greatest penetrationdepth when passing the, planef through ithe 1 of, the cutter.
  • the cutting edges peneperforation holes, said end surfaces beingloca'ted in cylindrical surfaces coaxial with the roll.

  • Figs. 2 and 3* show various steps in the'prodli ction of the holes 1 on a larger scale.
  • Fig. 4 showsj'a chip cutting tool in-theform' of a cutter.
  • Fig. 5 is' aii section through the patrix 'roll'and the cutter.
