Definitions

  • the invention relates to a lower blade shaft for a slitter for longitudinal cutting of films and tapes in strips having at least one lower blade wherein the lower blade shaft has a number of lower blades beyond the number of cuts, the lower blades are arranged at substantially regular intervals on the lower blade shaft, the distances between the Lower blades have a flexible choice of the width of the strips permitting, the Untermesserwalle having a plurality of cutting bushings, the cutting bushings each having a plurality of lower blades and a slitter for slitting films and strips into strips.
  • Slitters are used in particular for cutting aluminum foils and strips but also for cutting composites of aluminum and paper and of aluminum and plastic and for cutting other films, tapes and composite materials in a thickness range of a few microns to about one mm.
  • the films or ribbons to be cut can be both bright and painted.
  • the composites to be cut are produced, for example, by laminating or extruding.
  • the lower blade shaft according to the invention or the roller cutting machine according to the invention is exemplified by the cutting of aluminum foils or strips explained.
  • Under aluminum or aluminum materials are understood alloys that contain about at least 90% aluminum.
  • billets in widths between 900 and 2200 mm are poured in a first stage and rolled first to warm and finally cold to final thickness.
  • the aluminum semi-finished products industry produces the aluminum foils and strips in various final thicknesses and widths.
  • the final thickness is determined by the Stichab66 in the rolling process.
  • the final width is produced in one or more layers by slitting the strips or films on what are known as slitter-cutting machines.
  • the present invention also relates in particular to the so-called paper cut method.
  • the tape or the film is passed over a lower knife shaft with a certain wrap.
  • An immersed in the lower blade shaft upper blade which, for example, either as a razor blade or as Circular blade is formed, the aluminum cuts in one point in the manner of a scissors or knife cut.
  • the upper blade is conventionally pressed by a spring against the lower blade.
  • Newer methods use instead of a spring pneumatic cylinder or diaphragm cylinder.
  • the cutting widths for the tapes to be cut must be adjusted regularly.
  • the upper blade must first be set to the new cutting widths, which is possible with relatively little effort in a short time.
  • the entire lower blade shaft must be changed to incorporate a lower blade shaft, on which the lower blade are arranged on the, corresponding to the new cutting width axial position on the lower blade shaft.
  • fitting pieces are arranged between the lower blades on the lower blade shaft to produce the required distances. This causes a considerable amount of setup time and thus high costs.
  • a lower blade shaft which has only one side of the springs of a tongue and groove division cutting edges, is known from Swiss Patent CH 288 737.
  • the present invention is based on the object to provide a lower blade shaft or a slitter cutting machine, with which the set-up times for producing modified cutting widths and the use of other cutting methods are substantially reduced.
  • the previously derived and indicated object is achieved for a Untermessewelle for a slitter for slitting films and tapes in strips with at least one lower blade, characterized in that the lower blades are formed as two-sided cutting edges on the springs of a tongue and groove division of the lower blade shaft, said Cutting edges have a cutting angle of about 3 degrees and the grooves have a width of 0.8 to 2 mm, so that the Untertondernerwelle is useful for both the paper cutting method and for the razor blade cutting method. Characterized in that the lower blade shaft lower blade are arranged so that they allow a flexible choice of the width of zuzuharden strips, it is ensured that a change of the slitter can be made to changed cutting widths without downtime for conversions to the lower blade shaft.
  • the distance between the arranged on a lower blade shaft according to the invention lower blade can be reduced by the fact that the lower blade are formed alternately as a lower blade for left and right section. A reduced distance of the lower blade ensures a more flexible adaptation to desired cutting widths.
  • the alternate arrangement of lower blades for left and right cuts can be particularly suitable in that the lower blade as a double-sided Cutting edges are formed on the springs of a tongue and groove division of the lower blade shaft.
  • the lower blade shaft has a plurality of cutting bushings and the cutting bushings each having a plurality of lower blades, it is ensured that at a wear of the lower blade in certain areas of the lower blade shaft not the entire lower blade shaft must be replaced.
  • the cutting bushes which have a particularly high degree of wear, can be exchanged, while the cutting bushes having no or less wear can continue to be used.
  • the lower blade are arranged at a distance of about 0.5 to 10 mm from each other.
  • Particularly advantageous is the arrangement (division) of the cutting edges at a distance of about 0.8 to 2 mm from each other.
  • a groove width in the range of 0.8 to 2 mm has proven to be particularly suitable in terms of low pressure and in view of the provision of sufficient space for immersion of an upper blade.
  • a slitter for longitudinal slitting of films and tapes in strips with a lower blade shaft according to the invention and at least two dipping into the lower blade shaft upper blades.
  • the cutting bush 1 of a lower blade shaft according to the invention shown in Fig. 1 consists of an approximately 10 cm long hollow cylinder in the embodiment, on which on the outer cylindrical surface in a tongue and groove division 2 a plurality of lower blades 3 are arranged.
  • the lower blade 3 are, as shown in Fig. 2a) and b) clearly visible as two-sided cutting edges 4, 5 formed on the springs 6 of the tongue and groove division 2.
  • the distance between the cutting edges 4, 5 is in the illustrated embodiment about the grooves 7 about 0.8 mm and about the springs 6 about 1.2 mm.
  • an upper blade 8 is formed as the upper blade of a razor blade cutting system. Accordingly, a razor blade 9 immersed within a groove 7 in the lower blade 3 a.
  • Fig. 2b the immersion of a circular blade 10 is shown as a top blade in a scissors cutting system in the lower blade 3.
  • Fig. 2b) is further shown that the cutting edges 4, 5 have a cutting angle of about 3 °.
  • the springs 6 have in the embodiment of a lower blade shaft according to the invention shown in Fig. 2 on a height of about 2 mm.
  • a built-in a not shown in detail slitter embodiment of a lower blade shaft 11 according to the invention is shown.
  • the lower blades 8 are guided with the help of Obermesseranstellvorraumen 12.
