Definitions

  • the invention relates to a cross cutter.
  • a cross cutter is known from DE 43 21 163 A1.
  • the cross cutter is intended for cutting webs from flexible materials, with a cylindrical roller body rotatable around its center of gravity arrives at essentially one circumferential point with one extending parallel to the axis and in a metallic holder Recorded, radially facing knife is provided.
  • the Roller body consists of a plastic tube, with the holder separate generated and connected to the plastic tube.
  • the invention has for its object a cross cutter of the beginning mentioned type to develop in such a way that a simplified definition of the knife holder on the roller body and the cross cutter has a low-parts structure and in terms of manufacturing technology and economy Regarding simple and inexpensive to manufacture.
  • a cross cutter comprising one Roller body and at least one substantially parallel to the axis of rotation of the cross cutter, pointing radially outwards Knife that is at least two adjacent to each other with an axial distance Knife holder is included, each knife holder by at least a stud bolt directly connected to the roller body on the roller body is set.
  • the advantage here is that one is in the axial direction extending ledge, which is essentially the axial length of the roller body corresponds and is connected to at least one knife holder, not for use reached.
  • the bar and the roller body often consist of different materials.
  • the roller body is made of plastic, for example, the bar for example from steel.
  • the direct connection of the stud bolts to the roller body can, for example be formed by a press fit and / or the stud bolts are glued into congruently shaped recesses in the roller body.
  • the stud bolts can also be welded to the roller body.
  • the roller body consists of an epoxy resin reinforced with carbon fibers.
  • Cross cutter arrive in the production of sheets from a continuously fed Web made of a flexible material, for example paper for use.
  • Crucial is that the orbital speed of the cross cutter at the feed speed of the web to be cut is brought into line. It is beneficial if the cross cutter overall has only a comparatively low inertia, so that it exactly to the feeding speed of the dividable web is adaptable. If the roller body consists of a Carbon fiber reinforced epoxy resin, is its inertia greatly reduced, which greatly simplifies the orbital speed of the Adapt roller body to specified feed speeds.
  • the carbon fibers can be used to produce high-strength roller bodies which are particularly thin-walled and excellent have mechanical and dynamic resistance.
  • the carbon fibers can, for example, be distributed in a helical fashion be, with the carbon fibers crossing each other.
  • flexural and torsional strength is a good damping of natural vibrations achieved what about achieving a clean layover favors a long service life.
  • the studs are preferably laminated directly into the roller body. There is therefore no need for secondary fastening aids. By laminating the stud in the roller body results in an unsolvable, durable Connection.
  • the stud bolts can each have an external thread, the knife holder connected to the stud by at least one nut each are.
  • the assembly of such a cross cutter is particularly simple.
  • On the stud bolts laminated into the roller body each become a knife holder put on, the knife holder and the knife, for example, a can form pre-assembled unit, so that the unit as a whole on the Stud bolt is threaded.
  • the Possibility that the knife holder is first mounted on the respective stud bolts be that the knife in the threaded knife holder is used and that afterwards the knife holder with the nuts be attached to the stud bolts.
  • the roller body is tubular. Due to the tubular design Achievement of a low inertial mass further favored. With regard to one The most exact concentricity, the roller body is preferably hollow cylindrical educated. If necessary, there is the option of only a single knife to attach to the outer circumference of the roller body, the center of inertia is placed in the axis of rotation so that there is a distance from the axis of the plastic tube. Imbalance phenomena at initiation a rotary movement cannot occur even in such designs. Large-sized sheets can be separated from a flexible sheet be without the use of a roller body of very large Diameter required.
  • the wall of the roller body can move from the stud bolts in the radial direction to be completely permeated.
  • the advantage here is that the leadership of Studs especially in the corresponding recess of the roller body long and therefore particularly precise.
  • roller body and the stud bolts can be made of the same material be.
  • the advantage here is that the materials of the roller body and stud bolts have matching thermal expansion coefficients and different thermal expansions during the intended use of the cross cutter are safely excluded. Undesirable Tensions between the parts are avoided, which in view on a secure fixing of the studs in the roller body Advantage is.
  • the roller body 1 is designed as a hollow cylinder and consists of an epoxy resin reinforced with carbon fibers.
  • the radial Knife 3 pointing outwards extends essentially parallel to the axis of rotation 2 of the cross cutter and is received by the knife holders 4, 5.
  • six axially spaced Knife holders 4, 5 for use, each of the knife holders 4, 5 arranged on a stud 6, 7 and by a nut 9, 10 on the Roll body 1 is held.
  • the knife holders 4, 5 consist of a metallic one Material.
  • the carbon fibers within the roller body 1 are combined in strands and layer by layer like a continuous one Screw thread embedded in the jacket of the plastic tube, the angle of inclination, based on the axis of rotation 2 changes in layers.
  • the Carbon fibers within the epoxy resin have very good mechanical properties and dynamic properties of the cross cutter.
  • the stud bolts 6, 7 are laminated into the wall 11 of the roller body 1 and extend radially outward.
  • the knife 3 by means of the nuts 9, 10 in itself known way is connected to the roller body 1.
  • the one with the center of inertia coinciding axis of rotation 2 has a distance D from the axis 12 of the roller body 1. This results in an eccentric Orbital movement of the roller body 1 during the intended Use, however, not associated with unbalance and thereby is easy to control.
