Definitions

  • the present invention relates to an assembly for winding a plurality of elongated elements on a single spool.
  • the terms 'elongated elements' refer to elements the longitudinal dimension of which is more than hundred times larger than the cross-sectional dimensions. Common examples of elongated elements are round or flat steel wires, steel cords, textile yarns, copper strands, ...
  • Assemblies and apparatus for winding a plurality of elongated elements such as wires, cables or cords on one single spool are known in the art.
  • the unwinding of a plurality of elongated elements from such a single spool may cause difficulties and the subsequent twisting of the elongated elements, e.g. in a double-twisting machine, may lead to an unacceptable degree of fractures and processability problems.
  • the unwinding difficulties and the processability problems and fractures during the subsequent twisting may be due to a variation in diameter of the elongated elements during their winding, or may be due to the fact that elongated elements become entangled during their winding, or may be due to the fact that the elongated elements, although wound at the same time on the same spool, take different lengths on the spool.
  • GB-B-1 163 983 discloses a method for winding a plurality of elongated elements on one single spool whereby it is aimed at keeping the winding lengths of the elongated elements substantially equal to each other despite some variations in diameter of the elongated element.
  • the solution used to obtain substantially the same lengths is to increase the tension in elongated elements with an increased diameter in order to reduce the winding diameter and to decrease the tension in elongated elements with a decreased diameter in order to increase the winding diameter.
  • an assembly for winding a plurality of elongated elements on a single spool comprising following parts :
  • the assembly further comprises second monitoring means for measuring the tension of one individual elongated element which does not belong to the subgroup.
  • the revolution speed of the single spool is steered such that the tension of this individual element remains substantially constant and substantially equal to the tension of the elements of the subgroup.
  • all the individual elongated elements belong to the subgroup, and the revolution speeds of all the corresponding individual drive capstans is steered such that the tensions in all the individual elongated elements remain substantially constant and substantially equal to each other.
  • system further comprises grouping means for bringing the elongated elements parallel adjacent to each other before their winding.
  • grouping means prevent the elongated elements from jumping over each other and from entangling with each other.
  • grouping means together with the means for keeping the tensions in the elongated elements substantially constant and equal result in substantially equal lengths wound upon the single spool.
  • the assembly further comprises means for realizing a to and fro movement lengthwise of the single spool and relative to the single spool, means for measuring an accumulation of that elongated element that is nearest to one of said ends of the single spool and means for automatically reversing the movement towards the other of said ends of said single spool upon an accumulation being detected.
  • the to and fro movement is 'relative' to the spool, which means that either the elongated elements are moved with respect to the spool or that the spool is moved with respect to the elongated elements.
  • FIGURE 1 illustrates three wires 10, 12, 14 the tension of which is measured by passing them respectively over individual dancer arms 16, 18, 20 before winding them simultaneously on a single spool 22.
  • Spool 22 is driven via a belt 24 by an electric motor 26.
  • the position of dancer arm 16 determines the revolution speed of electrical motor 26, and, as a consequence, of revolution speed n w of the spool 22, in a way well known in the art such that the tension of wire 10 remains substantially constant.
  • This control of the speed of electrical motor 26 is indicated by a hatched arrow 28.
  • the wires 10, 12, 14 are individually driven by distinct capstans 30, 32, 34 which are in their turn driven respectively by electrical motors 36, 38, 40 by means of belts 42, 44, 46.
  • the position of dancer arms 18 determines the revolution speed of electrical motor 38, and as a consequence revolution speed n 2 , such that the tension of wire 12 remains substantially constant and substantially equal to the tension of wire 10.
  • the position of dancer arms 20 determines the revolution speed of electrical motor 40, and as a consequence revolution speed n 3 , such that the tension of wire 14 remains substantially constant and substantially equal to the tension of wire 10.
  • the revolution speed n 1 of wire 10, the tension of which determines the revolution speed n w of spool 22, is adjusted beforehand.
  • FIGURE 2 illustrates an alternative way of winding three individual wires 10, 12, 14 on a single spool 22.
  • the main difference with the assembly as illustrated under FIGURE 1, is that in the assembly of FIGURE 2 all the revolutions speeds n 1 , n 2 and n 3 are determined, at least indirectly, by the position of dancer arms 16, 18 and 20 while revolution n w of spool 22 is adjusted beforehand.
  • the individual wires 10, 12, 14 are brought together parallel adjacent to each other by means of sets of guiding pulleys 50, 52 and, for example, by means of a comb 54 before their winding on spool 22. This bringing together of the individual wires into a set of parallel wires is done to prevent the wires from entangling with each other and from jumping over each other.
  • possible accumulation 56 of the left wire 10 that is nearest to the left flange is monitored and once an accumulation near the left flange is detected, e.g. by detecting a raise in the tension of wire 10, the to and fro movement lengthwise of the spool is reversed from the right to left direction to the left to right direction, which is indicated by arrows 58 and 60.
  • possible accumulation 62 of the right wire 16 that is nearest to the right flange is monitored and once an accumulation near this right flange is detected, e.g.
  • a wire winding system for obtaining a uniform winding for one single wire has been disclosed into more detail in US-A-3,967,787.
  • the present invention differs herefrom that a plurality of wires are wound on the spool on that accumulation near the right flange is only monitored on the right wire (which is nearest to the right flange) and that accumulation near the left flange is only monitored on the left wire (which is nearest to the left flange).
  • Individual wire drawing machines, multiple wire drawing machines or the unwinding of individual wires from spools may be situated upstream of the assemblies according to the invention.
  • Spools wound according to the present invention with a plurality of steel filaments have already been used in the manufacture of steel cords.
  • the double-twisting of a 1x3 steel cord and of a 2+2 steel cord was done without increase of fractures and without substantial processability problems.
  • Spools wound with steel filaments according to the present invention have equal lengths of the steel filaments wound on the spool. This can be derived from the experiment that when all the steel filaments which are wound on the same spool, are unwound over several meter and under the same tension, they all exhibit the same looseness. Such spools with multiple steel filaments of substantially the same length can be used without substantial problems in the braiding of steel filaments for reinforcement of rubber hoses.
  • Spools wound with a multiple of steel filaments or with a multiple of steel cords according to the present invention can also be advantageously used in the manufacturing process of rubber tires.
  • Conveniently large creels comprising a high number of spools are used in the manufacture of rubber tires.
  • Use of spools with multiple filaments or with multiple cords greatly reduces the size of the creels and the fact that the filaments or cords have been wound under substantially the same tension parallel to each other means that no entanglement has occurred and that subsequent unwinding poses no great difficulties.
