  • Polyurethane (PU) or plastic have the tensile force transmission in most cases
  • each one or more strands, threads or filaments of different types of fibers are arranged, often beaten or twisted and / or formed as a fiber bundle or filament yarn.
  • the reinforcements are firmly bound in the elastomeric material, e.g. Rubber vulcanized in the rubber matrix.
  • Connections of reinforcing elements in elastomeric components subject to high mechanical stress, for example in drive belts in the form of toothed belts, have hitherto been rather uncommon. So toothed belts are still produced mainly with cords without splice as a strength and tensile strength. Unused residual quantities of cords remain on the supply reels of the Cord suppliers. This results in an increased amount of waste during production.
  • a splice as a combination of reinforcements in a drive belt, for example, must meet high requirements.
  • Such a splice must not only have a sufficient tensile strength in the later operating state under constant bending changes, but must also be able to withstand the forces arising during the production of the drive belt, here, for example, in a winding process without problems
  • such a splice must not lead to irregularity in the belt structure, i. no thickening, no visible knot, and also no reduction in the flexural elasticity or the yieldable bending stress of the belt.
  • the object was by providing a suitable connection technique for strength carrier in elastomeric material on the one hand the
  • Strengthen provided elastomer components to improve in which, for example, a so-called winding process in which strength carrier are placed on a constructed of elastomeric material body of rotation, which is later re-separated as a multiple component, no longer in half or still filled winding (drum ) must be stopped without the remaining remaining cord can be used.
  • the splice or connecting region has substantially the same number of strands, twines or filaments as the adjacent non-spliced regions and is surrounded by a covering enclosing the splices or filaments under pressure enclosing under pressure.
  • the resulting splice is a very bendable and flexible joint that does not interfere with the continuous winding process and that can remain in the belt without adversely affecting the essential belt properties.
  • connected ends are formed by respective removal of a number of strands, twines or filaments in the splice or connection area thinned / tapered, in particular by removing an equal number of strands, twines or filaments at both ends.
  • Toothed belt for use in a belt drive the splice area as strong as the other areas.
  • a further advantageous embodiment consists in that the wrapping consists of a yarn wrap applied under tension, in particular of a yarn with a smaller diameter than that of the strands. This simplifies the manufacture of the splice and produces no or only a small application, i. a barely noticeable thickening in the region of the splice.
  • a further advantageous embodiment is that the splice length is between 50 and 400 mm.

  • Flat belts, V-belts, V-ribbed belts and toothed belts can be provided in a simple manner by appropriate splicing length design with splices adapted to the tensile loads and flexural strength.
  • a further advantageous embodiment is that the splice is used to connect two ends of reinforcements made of glass fibers, aramid fibers, polyamide fibers (PA) or polyethylene fibers (PE). With all these materials, the splice according to the invention can be used without difficulty.
  • a particularly suitable method for producing a splice according to the invention is that
  • Another advantageous, because very simple design of the manufacturing process is that an equal number of separated strands, twines or filaments of both ends is connected together preferably such that each half of the originally existing strands, twines or filaments connected to each other and the other Half is separated.
  • Another embodiment of the method which is also advantageous because of its simplicity, is that the covering is applied by means of a wrapping of the splice applied with tension with a yarn.

  • the strands 7 and 9 are twisted together / twisted in this case.
  • first strand 7 and second strand 9 are provided along the length of the splice with a sheath 10 compressively compressing the strands, by wrapping the splice with a yarn 11 under tension is applied.

  • Fig. 3 shows once again a photo of a finished splice with the splice length 12 of 130 mm. It will be appreciated that, by having substantially the same number of strands in the splice as in the adjacent non-spliced portions, the thickness of the strength member, including the sheath enclosing the splice under pressure, will not appreciably exceed the original thickness of the strength member outside the splice. The splice is thus equally highly resilient and does not wear in the finished timing belt.

Abstract

L'invention concerne une épissure servant à relier deux extrémités (5a, 5b) de supports de résistance composés de torons, de fils retors ou de filaments (7, 8, 9) enfoncés ou amenés en rotation dans un élément élastomère (2), en particulier à relier des câbles dans des courroies d'entraînement ou des bandes transporteuses. L'épissure ou la zone de liaison comprend sensiblement le même nombre de torons, de fils retors ou de filaments que les zones adjacentes non épissées et est entourée par une enveloppe (10) enveloppant sous pression les torons, les fils retors ou les filaments restés dans l'épissure ou dans la zone de liaison.
