Definitions

  • the invention relates to a method for producing a multi-layer, single-strand and compact reinforcement cord for elastomeric products in a stranding process by feeding metal wires of the same diameter into a plurality of stranding points one behind the other, two or more metal wires being fed to the first stranding point, or a metal wire to the first and six Metal wires are fed to the second stranding point and reinforcing cords made by this method.
  • Such a method and the reinforcing cords produced by this method are known from DE-OS 29 34 012.
  • a stranding point is provided for one layer of metal wires.
  • the metal wires are first subjected to a false twist before they are fed to the actual stranding device.
  • the application of the false twist is also intended to ensure that the length of this metal wire required depending on the position of the individual metal wire in the finished rope assembly is achieved. Ensuring the corresponding length of each metal wire is also supported by rollers that are regulated in terms of their speed depending on the voltage.
  • the object of the present invention is to provide a method and reinforcing cords of the type mentioned at the outset, in which the disadvantages described above do not occur, and in which it is ensured that each metal wire in the finished product The rope association actually occupies the position intended for it. It is also an object of the invention to provide a method and reinforcing cords by means of which or in which excess lengths of individual metal wires in the finished rope assembly are effectively avoided.
  • the position of further metal wires can be determined exactly by feeding the further stranding points following the first stranding point in each case at most as many metal wires as there are spaces in which each metal wire supplied already has at least two existing metal wires can be brought into contact.
  • the position of further metal wires can be achieved exactly by feeding the further stranding points following the second stranding point in each case at most as many metal wires as there are enough places for each metal wire to be fed can be brought into contact with at least two existing metal wires.
  • the metal wires are no longer deposited in layers. Rather, at most as many metal wires are inserted in the respective stranding point as there are many stable storage points in the already pre-formed base rope body, thereby creating further stable storage points in the base rope body, which enable the stable storage of further wires in a subsequent stranding point.
  • a stable storage point is always only given if a newly added metal wire can be brought into contact with at least two existing metal wires. This metal wire is thus placed in a gap, whereby it is supported on two existing metal wires, so that its spatial position is fixed.
  • the length required for the respective metal wire can be predetermined simply and exactly by conveying the metal wire to its stranding point with a corresponding excess length.
  • the excess length required in each case can be calculated from the rope construction to be created, as will be shown below.
  • the respective excess length is expediently conveyed by preforming the metal wires corresponding to the excess length.
  • the metal wires are advantageously preformed by bending the metal wires over nipples, pins or edges. If this bending of a metal wire occurs in such a way that the nipple, the pin or the edge is circumferential over the circumference of the metal wire, then this metal wire is pre-shaped in a helical shape. If the bend always remains at the same point on the circumference of the metal wire and if the metal wire is bent again at a distance from the first bend in the opposite direction, the metal wire takes the form of a plane wave.
  • the exact length of a metal wire in an outer layer can be preformed via the pitch and diameter of the screw Metal wire, or be determined via the amplitude and wavelength of the wavy preformed metal wire.
  • the metal wires can also be preformed by means of torsion.
  • the coils from which the metal wires are withdrawn must be rotated such that the respective metal wire is twisted in itself.
  • the advantages of the method according to the invention are, on the one hand, that the false twist of the rope assembly required in the known method is no longer necessary when producing a multi-layer, single-strand and compact reinforcing cord.
  • the reinforcement cords produced by the method according to the invention are notable for their compactness.
  • the individual wires of the reinforcement cord produced according to the invention always take up the same space, viewed over the length of the reinforcement cord.
  • the preforming of the wires before feeding them into the stranding points does not have a disruptive effect in the finished reinforcing cord, because this preforming is removed again during the actual stranding process, for example in a double-twist twisting machine.
  • the object of the invention is also achieved by a multi-layer, single-strand and compact reinforcing cord for elastomeric products, consisting of at least 12 individual wires of the same diameter, in which the innermost layer consists of one to four individual wires, and each individual wire Across the length of the cord always occupies the same position in cross-section, produced by feeding the individual wires at several, one behind the other stranding points, whereby initially 2 to 4 or 1 and then 6 individual wires and at the following stranding points each as much individual wires were fed as there were spaces, in which each supplied metal wire can be brought into contact with at least two existing metal wires.
  • the length of the individual wires per lay length of the reinforcement cord preferably increases from the inside to the outside, depending on their position in the cross section of the reinforcement cord.
  • a reinforcement cord is particularly favorable in which external individual wires with at least three and internal individual wires with six other individual wires are predominantly arranged in linear contact over the length of the reinforcing cord.
  • FIG. 1 shows a device with which the method according to the invention can be carried out.
  • the drain gate for wire spools 2 is designated.
  • the individual wires E are fed from the wire coils 2 to the actual stranding device via wire guides 14.
  • This stranding device contains five wire placement points 4.1 -4.5, by means of which the five stranding points are fixed.
  • a distributor plate 3.1-3.5 is arranged in front of each wire deposit point 4.1-4.5 and is designed as a perforated plate with guide nipples (not shown).
  • the wire storage points 4.3 - 4.5 are shown wider in the drawing, because they have to be stronger. In addition to the usual centering nipple, these wire storage points 4.3 - 4.5 also contain press jaws (also not shown).
  • a step preform head 6.4 and 6.5 is arranged in front of the wire storage points 4.4 and 4.5, to which the individual wires E are fed via a distributor plate for the step preform head 5.4 or 5.5.
  • the folded individual wires are fed to a double-twist machine (outer-inner twine) 7, in which the multilayer, single-strand and compact reinforcing cord now produced is wound onto a cable spool 8.
  • a double-twist machine outer-inner twine 7
  • the multilayer, single-strand and compact reinforcing cord now produced is wound onto a cable spool 8.
  • a step preform head 6 is shown schematically enlarged in FIG.
  • the individual wires E can be preformed to a helical line (without swirl stopper) or to a flat wavy line (with swirl stopper) with such a step preforming head.
  • the step preform head 6 consists essentially of two disks 9, 10, in which the preform eyelets 11 and 12 are arranged on the two partial circles M1 and M2.
  • the preform eyelets 11 and 12 For each individual wire E, which is to be preformed in the step preform head, there are two preform eyelets 11 and 12 in the disks 9 and 10.
  • the preform eyelets 11 and 12 each have an edge over which the Individual wires E are bent.
  • the decisive factors for the degree of preforming are the gap width, the gradation of the pitch circle diameter and the angle of rotation which the preform eyelets 11 and 12 belonging to each other form.
  • the preformed individual wires are brought together through the wire storage point 4 in the stranding point 13.
  • Coil 2 is a tangential draw for individual wires E, which are fed to the stranding point 13.1 via wire guides 15.
  • a wire spool 16 is arranged in a DD twister for a single wire 18, over which individual wires are preformed by means of torsion according to the known Arundel method.
  • the wire guides are designated 17 here.
  • the torsion preforming of the individual wires can be used alone or in conjunction with the step preforming head 6. Both devices have the purpose of ensuring the excess length required for the corresponding position of the individual wire.
  • the twisted wires can then be fed to the stranding points 13.2, 13.3 and others.
  • FIG. 4 the layered feeding of the individual wires known from DE-OS 29 34 012 is shown schematically.
  • three stranding points 13.1, 13.2 and 13.3 are provided for producing a multi-layer, single-strand and compact reinforcing cord consisting of twenty-seven individual wires.
  • the first stranding point 13.1 becomes three wires E
  • the second stranding point 13.2 nine individual wires
  • the third stranding point 13.3 once fed fifteen individual wires.
  • the individual wires present in the stranding point 13.1 to 13.3 are shown in the position intended for them, in black those wires that run towards this stranding point, and as a circle those wires that are already at the previous stranding point or the previous ones Stranding points were fed. ,
  • FIG. 5 schematically shows how the individual wires are fed to the five stranding points 13.1 to 13.5 required for this by the method according to the invention. It can be seen from the cross sections shown in the upper part of FIG. 5 that only as many wires (black) are fed into each stranding point as there are spaces in which each fed metal wire (black) comes into contact with at least two already existing metal wires (circular ring) For this purpose, as can be seen from FIG. 4, three individual wires can be fed in the second stranding point 13.2, six in the third stranding point 13.3 and nine in the fourth stranding point 13.4. If, as shown in FIG. 5, the reinforcing cord is again to consist of twenty-seven individual wires, the last six individual wires are fed in at the stranding point 13.5, which results in the reinforcing cord C, which is then stranded.
  • a reinforcing cord is again shown in FIG. 6, which consists of twenty-seven individual wires, and three in the center Individual wires dl are arranged on the pitch circle with a diameter Dl. Three further individual wires d2 lie on a pitch circle diameter D2 (not designated for the sake of clarity). Further individual wires are arranged as follows: six individual wires d3 on pitch circle D3, six single wires d4 on pitch circle D4 (not labeled), three single wires d5 on pitch circle D5 (not labeled) and six single wires d6 on pitch circle D6.
  • the lay lengths and lay direction of all three wire layers must be the same.
  • the rope is produced in one operation from twenty-seven individual wires on an outside-inside twisting machine, as shown in FIGS. 1 and 5.
  • the thread factor En (effective wire length: lay length) is different for all three wire layers, and there are also additional differences within the 2nd and 3rd wire layers depending on the position of the respective wires.
  • the lay angle of the individual wire groups is calculated as follows: where D n is the neutral rope diameter for the respective wire group and S is the lay length (Fig. 6). From the equation the integration factor E n results.
  • Table I below gives an overview of the different twists at 27 x 0.22 for the different wire layers and wire groups.
  • the table shows that 18.333 mm wire length for a lay length of 18.0 mm are required for the wire group 6 of the 15 group, whereas only 18.018 mm are required for the group 3 group of three.
  • the group of three of group 1 would have an excess length of 1.75% compared to the wires of group 6 after the twisting.
  • the other wire groups have correspondingly smaller overlengths compared to group 6.
  • the excess wire length of the triad means that if the ropes are treated for other reasons - e.g. Straighteners, false twist effects, winding tension etc. - these are pushed together like small carpet folds to form a large carpet fold and emerge from the rope assembly as eyelets.
  • FIG. 7 shows a micrograph of the cross section of a reinforcement cord of the construction type 27 ⁇ 0.22 + 0.15 F produced according to the invention.
  • the reinforcing cord thus consists of twenty-seven single wires E with a diameter of 0.22 mm and a loop wire W with 0.15 mm diameter, which was flat-rolled for the purpose of better compactness of the reinforcing cord.
  • the sample was prepared for the microscopic picture in the following way.
  • a reinforcement cord produced according to the invention was poured into a plastic.
  • the hardened plastic block was cut in a direction perpendicular to the reinforcement cord axis. The cut surface was then ground and polished.
  • the sample produced in this way was enlarged and photographed under the microscope.
  • the reinforcement cords produced according to the invention have a very uniform cross-sectional shape of the reinforcement cords and thus a compactness that can no longer be surpassed.
  • Cord A 6 individual wires with a diameter of 0.22 mm were fed in at the first stranding point 6 and at the fourth stranding point.
  • the first stranding point 3, the second 3, the third 6, the fourth 9 and the fifth 6 individual wires with a diameter of 0.175 mm (cord B) and 0.22 mm (cord C) were fed.
  • the further design features of the cords produced by the process according to the invention can be found in Table II.
  • the diameter of the cord A produced according to the invention is reduced by 4.3% compared to the known cord X in a layer construction
  • the cord B produced according to the invention is reduced in diameter by 4.5% compared to the known cord Y in the layer construction
  • the cord C according to the invention a diameter reduction of 3.1% compared to the known cord Z in a layered construction.
