Definitions

  • the present invention relates to a dividing comb with a multiplicity of mutually spaced lamellae for feeding a steel cord family from steel threads or steel cords which run parallel and at least substantially in one plane to a steel cord calender, and a device for a dividing comb according to the invention.
  • steel cord calenders are used to produce rubberized steel cord sheets, which are subsequently cut into corresponding single sheets and are used, for example, as belt layers in the manufacture of vehicle tires.
  • the steel cord thread sheet is usually supplied by a gate equipped with a large number of steel cord spools, the individual cords being manually threaded through the spaces between the individual lamellae of the dividing comb.
  • a dividing comb according to the prior art has a plurality of equally spaced lamellae, the mutual spacing of which corresponds to the desired thread division (number of steel cords per 10 cm).
  • the steel cord thread family then runs over a dividing roller which has a multiplicity of guide grooves, the mutual spacing of which corresponds to the spacing of the steel cords which is predetermined by the thread division on the dividing comb.
  • the steel cord thread sheet runs over this dividing roller into the press nip between two calender rollers.
  • a number of time-consuming steps are required if the thread pitch of the rubber-coated steel cord sheets produced is to be changed.
  • the calender is shut down, the steel cords are cut off and remnants of the mixture are removed from the calender.
  • the dividing comb that is no longer suitable is removed.
  • the creel is routed to a set-up station, where the individual steel cords are threaded into a dividing comb with the desired thread division.
  • the creel is brought back into its calender position, the new dividing comb is mounted and finally the matching dividing roller is fixed after removing the other dividing roller.
  • the mixture must be preheated and fed into the nips.
  • the invention has now set itself the task of finding measures that help to reduce the time-consuming process described.
  • the object is achieved according to the invention in that the dividing comb has lamellae arranged in a fan-like manner.
  • a dividing comb according to the present invention it is possible to change the thread pitch over a relatively wide range by simply moving and fixing it in different positions, without having to change the dividing comb. Since it is only necessary to change the dividing roller, which is possible within a few minutes, there is also no need to clear out the mixture from the calender.
  • the particular advantages of the division comb according to the invention therefore lie in the enormous saving of time and the ease of use. Another advantage to be mentioned is that the total number of division combs available is considerably reduced.
  • the slats are conical in cross section.
  • the arrangement of the lamellae is preferably such that the gap between all lamellae on the dividing comb has a constant width. This design variant allows a particularly precise guidance of the individual steel cords in every possible position.
  • One embodiment of the dividing comb that is simpler in terms of manufacture is that the lamellae have a constant width over their entire length.
  • the handling of the dividing comb according to the invention for changing the thread pitch is easily possible if the dividing comb on the comb carrier is at least substantially displaceable in a direction normal to the running direction of the steel cord thread sheet and is arranged to be fixable in different positions.
  • the invention further relates to a device arranged upstream of a steel cord calender for a dividing comb designed according to the invention.
  • this device has a pair of guide rollers or the like, between which the steel cord thread sheet runs.
  • the guide rollers help to ensure that the steel cords are guided parallel and essentially in one plane through the dividing comb.
  • the guide rollers are advantageously displaceable on the device and can be fixed in different positions.
  • FIG. 1 shows schematically and in side view the basic arrangement of a dividing comb with associated dividing roller
  • FIGS. 2 and 3 each schematically in FIG Top view of two variants of a division comb according to the present invention.
  • the steel cord calender itself is not the subject of the present invention and is therefore not shown in the drawing figures.
  • the calender can be, for example, a two-roll calender (cold process) or a four-roll calender (warm process).
  • Fig. 1 shows the dividing roller 1 arranged in front of the press nip of the calender, a dividing comb 2 positioned in front of the dividing roller 1 and a steel cord family 3, the individual steel cords of which are threaded through the dividing comb 2 and run over the dividing roller 1 into the press nip between two calender rollers.
  • the dividing roller 1 has in a known and therefore not shown manner a plurality of circumferential guide grooves for receiving or guiding the individual steel cords.
  • the mutual spacing of the individual guide grooves corresponds to the thread spacing set on the dividing comb 2, which is usually called thread division.
  • a thread pitch of 80 means that 80 threads of steel cord per 10 cm are present both on the dividing comb 2 and on the dividing roller 1.
  • the family of threads is supplied in a manner known per se from a gate equipped with a large number of bobbins, which is likewise not part of the present invention.
  • the dividing comb 2 shows a first exemplary embodiment of a dividing comb 2 designed according to the present invention.
  • the dividing comb 2 consists of a solid, metallic frame 5, which is closed on all sides, and of a multiplicity of likewise metallic slats 6.
  • the frame 5, which is designed in a rectangular shape consists of two side parts 5a and one upper and lower part 5b, 5c, the slats 6 running or arranged between the upper and lower part 5b, 5c.
  • a dividing comb usually has between 800 and 1,200 lamellae, in the drawing figures 2 and 3 a much smaller number of lamellae is shown for the sake of simplicity.
  • the slats 6 have a conical cross-section, in such a way that their cross-section starting from the upper frame part 5b to the lower frame part 5c becomes too small.
  • the mutual arrangement of the slats 6 between the frame parts 5b, 5c takes place in a fan-like manner and in such a way that there is an equal distance between the sides of the slats 6, which are adjacent to one another is slightly larger than the diameter of the threaded steel cords 4.
  • Fig. 1 the direction of displacement of the division comb 2 is symbolized by the double arrow.
  • the displacement and also the respective position fixing of the dividing comb 2 takes place by means of suitable mechanisms, which are provided, for example, on the comb carrier (not shown).
  • guide rollers 7 or the like can be positioned just above and just below the steel cord thread family in order to additionally fix the selected steel cord spacing or the selected thread pitch.
  • the guide rollers 7 can be arranged on the comb carrier or a separate supporting part in a suitable manner.
  • Fig. 3 shows a further possible variant of the invention, in which case a dividing comb 2 'with fins 6' is provided which have a cross-sectional width which is constant over their length and are also arranged such that they run from the frame upper part 5b to the frame lower part 5c in a fan-like manner.
  • this variant allows the individual steel cords more freedom of movement in the transverse direction in those positions where a larger cord spacing (smaller thread division) is desired, this has no disadvantages, since the dividing roller also holds the individual cords in position in their guide grooves.
  • a variation in the thread division can take place, which is in the range of approximately 10 to 15 threads per 10 cm.
  • a change from a thread division from 95 to a thread division from 80, or from a thread division from 40 to a thread division from 50 can take place.
  • the advantages of the present invention are in particular an enormous saving in time, but also in the fact that the total number of division combs available can be considerably reduced.
