Definitions

  • the present invention relates to a dividing comb with a multiplicity of mutually spaced-apart slats for feeding a steel cord family from steel threads or steel cords running in parallel and at least essentially 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 sheet then runs over a dividing roller which has a multiplicity of guide grooves, the mutual spacing of which corresponds to the spacing between 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 designing a division comb for a steel cord thread set so that the described time-consuming process is largely avoided.
  • the dividing comb has lamellae arranged in a fan-like manner, the lamellae being conical in cross section and a larger lamella cross section corresponding to the setting of a lower thread pitch.
  • 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 ensures that the fin spacing is matched to the steel cord diameter in every possible thread division.
  • 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 direction of travel 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 family 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
  • FIG. 2 schematically shows a variant of a dividing comb according to the present invention in plan view.
  • 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 (hot 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 an 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 from two side parts 5a and one upper and lower part 5b, 5c, the slats 6 running or being arranged between the upper and lower parts 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 mutually adjacent slats 6, which is slightly larger than the diameter of the threaded steel cords 4.
  • 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.
  • 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.
