Definitions

  • the invention relates to a textile rope, the surface of which is formed by a tubular braid consisting of a plurality of strands, and in which there is a splice connection, preferably machine rope provided for running, in particular paper machine threading rope, the two rope ends joined there at the splice point are stuck.
  • the invention further relates to a method for producing the splice connection of such a rope.
  • Ropes of the aforementioned type can be braided hollow ropes made of textile fiber material, in particular yarns, or also core ropes, in which a core formed from textile fiber strands is surrounded by a sheath which is formed as a tubular braid which consists of a plurality of strands made of textile material .
  • Such ropes are widely used, for example, as ropes in paper machines. The so-called splice connection is often used.
  • Plug-in splice is provided, which is formed by inserting the end sections of the two rope ends into the opposite or complementary rope end, whereby as soon as the rope is under tensile stress, a contraction of the hose-like braid, which forms the surface of the rope, causes it to jam the end sections of the rope ends inserted into the respective complementary rope ends (see, for example, US 3,561,318 A).
  • these known splice connections have the disadvantage that the rope has a substantially greater thickness over the entire length of these connections than is present outside the splice connection in the rope concerned;
  • the thickness in the area of the splice connection over its entire length can be 130% greater than the thickness of the rope outside the splice connection, and the thickening in the area of the splice connection which occurs due to such a splice connection can also be considerable in the case of core ropes , for example about 80%.
  • the rope of the type mentioned in the introduction is characterized in that the end section of the other rope end inserted into one rope end and the end section of one rope end inserted into the other rope end each several strands are subdivided, each of these strands protruding somewhat outwards through the braid forming the surface of the rope and thus being held in the braid, and the points of passage of these strands following one another at a mutual spacing, seen in the longitudinal direction of the rope.
  • the above-mentioned tapering or thinning of the end sections of the rope ends inserted into the respective opposite rope end, away from the center of the splice, can be carried out by a corresponding tapering or thinning of the rope core and, as with the strands of the mentioned end sections, when a core rope is present Exit of the fiber strands forming the rope core from the braid forming the rope surface, which forms the sheath for a core rope, are supplemented.
  • a preferred embodiment of the subject matter of the invention is characterized in that that the rope has a rope core formed from fiber strands and the ends of these fiber strands forming the rope core at the splice point at a distance from the center of the splice, at which the two end sections of the rope ends are inserted into the opposite end of the rope, through which the surface of the rope protruding braid protrude slightly outwards and are thus held in the braid. It is advantageous here if the ends of the fiber strands forming the rope core protrude from the braid forming the surface of the rope at a plurality of successive passage points, seen at a mutual distance in the longitudinal direction of the rope.
  • the passage points of the ends of the fiber strands forming the rope core, seen in the longitudinal direction of the rope lie in that area of the relevant rope end in which the strands forming the tubular braid of the rope surface of the complementary rope end also project outwards .
  • a particularly uniform course of the rope thickness in the area of the splice connection and also a particularly uniform transition of the tensile load to the rope core can be achieved.
  • the area in which both ends of the fiber strands forming the rope core of the respective rope end as well as strands which form the tubular braid of the complementary rope end project outwards in a rope end can advantageously, viewed in the longitudinal direction of the rope, have a length of 1 cm to Have 80 cm.
  • the mutual distances between the passage points of the mentioned strands forming the end sections of the rope ends and the possibly existing fiber strands forming the rope core through the tubular braid forming the rope surface are advantageously selected in the range from 1 to 20 cm, in Seen longitudinal direction of the rope.
  • the method according to the invention for producing the splice connection of a rope designed as mentioned above is characterized in that first of all the end section of the complementary rope end is inserted into the two rope ends at a point later forming the center of the splice connection to be made, and then the individual strands of these end sections are inserted through the hose-like braid of the relevant rope end is grasped and detached from the accompanying strands and, viewed in the longitudinal direction of the rope, spaced-apart passage openings are pulled out of the hose-like braid of the respective rope end, after which the portions of these strands protruding from these passage openings are shortened.
  • the splice connection is formed in the case of a core rope, it is advantageously additionally provided that the ends of the fiber strands forming the core of the rope ends are pulled out of the interior of the rope at a point at a distance from the center of the splice connection to be formed, and then the end sections of the rope ends are inserted into the other end of the rope, after which the strands forming the end sections and the fiber strands forming the rope core are gripped, released and pulled out.
  • FIG. 2 likewise shows a schematic view of the area of the embodiment of an inventive core rope that has the splice connection; 3 to 8 in a schematic representation individual phases of the production of the splice connection in the case of a hollow rope designed according to the invention; and FIGS. 9 to 15 show a schematic illustration of individual phases in the production of the splice connection in the case of a core rope designed according to the invention.
  • the textile rope 1 shown in Fig.l is a hollow rope, which is formed from a tubular braid 2, which also forms the surface 3 of this rope.
  • this network 2 is only indicated in places in the drawing figures.
  • a splice connection 5 is present in the rope 1 between the boundaries 4 indicated by dash-dotted lines.
  • the two rope ends 6, 7 joined there are inserted into one another by inserting the end section 9 of the other right rope end 7 into the left rope end 6 in FIG. 1 and the end section 8 into the other right rope end 7 one of the left rope ends 6 is inserted.
  • the end section 8 is divided into a plurality of strands 10 and the end section 9 into a plurality of strands 11; each of these strands 10, 11 protrudes somewhat through the braid 2 forming the surface of the rope 1, and is thus held in the braid 2.
  • the passage points 12 of these strands 10, 11 follow one another at a mutual spacing 13, seen in the longitudinal direction 14 of the rope 1.
  • the strands 10, 11 protrude a short distance, e.g. 0.5 to 10 cm, out of braid 2.
  • the mutual distances 13 of the passage points 12 are selected in the range from 1 cm to 20 cm.
  • the rope 15 shown in FIG. 2 is a textile core rope, in which the tubular braid 2 forms the rope sheath that surrounds a rope core 16.
  • the splice connection 5 extending between the boundaries 4 also connects the cable ends 6, 7 to one another in this case, the end sections 8, 9 of the cable ends 6, 7 being inserted into the respective opposite cable end in the middle 18 of the splice.
  • the rope core 16 is formed from fiber strands 17 which are spaced 19 from the center 18 of the splice by the structure forming the surface 3 of the rope. braid 2 protrude slightly outwards and are thus held in braid 2.
  • the passage points 20 of the fiber strands 17 are arranged in the longitudinal direction 14 of the rope 15 at mutual distances 21 of approximately 1 to 20 cm.
  • the strands 10, 11 of the end sections 8, 9 protrude somewhat outwards through the braid 2, the passages 12 of these strands 10, 11 following one another at a mutual spacing 13 in the longitudinal direction 14 of the rope 15.

  • the passage points 20 are provided only in a part of the area 22, namely in the area 23, in which both ends of the fiber strands 17 and ends of the strands 10 and 11 protrude outwards.
  • the partial area 23, as seen in the longitudinal direction of the rope 15, can have a length of up to 80 cm.
  • the successive passage of the strands 10 and 11 through the braid 2 from the center 18 reduces the overall cross section of the end sections 8 and 9 consisting of the strands 10 and 11, while in opposite directions in the areas 23 of the total cross-section present in the rope 15 of the core 16 formed from the fiber strands 17 increases as seen from the center 18. This is advantageous for keeping the rope diameter constant and also for power transmission in the area of the splice connection.
  • the middle 18 can first be attached to the two rope ends 6, 7 to be connected, which consist of a textile, tubular braid the splice connection to be made and the size Mark zen 4 of the splice connection to be made and then insert the end section 9 of the rope end 7, as shown in FIG. 4, by means of a needle 24 next to the location of the center 18 into the rope end 6, up to the limit 4 at this rope end, and there again Pull out of the rope end until the markings of the middle 18 previously attached to the rope ends 6, 7 almost coincide, as shown in FIG. 5.

Abstract

Corde textile (1, 15) dont la surface (3) est formée par un tissage (2) de type boyau constitué d'une pluralité d'écheveaux, et qui comporte un raccord (5) par épissure. Sur le site de l'épissure, le tronçon terminal (9) de la première extrémité (7) de corde est introduit dans la seconde extrémité (6) de corde et le tronçon terminal (8) de la seconde extrémité (6) de corde est introduit dans la première extrémité (7) de corde. Les tronçons terminaux (8, 9) sont tous deux divisés en plusieurs écheveaux (10, 11), chacun de ces écheveaux (10, 11) faisant saillie vers l'extérieur à travers le tissage (2) formant la surface (3) de la corde (1, 15) et se trouvant donc ainsi maintenu dans le tissage (2). Les sites (12) sur lesquels ces écheveaux (10) font saillie vers l'extérieur se trouvent à des écarts réguliers (13), dans le sens de la longueur (14) de la corde. Selon le procédé de fabrication d'une corde (1, 15) de ce type, chaque tronçon terminal de l'extrémité de corde est introduit dans l'extrémité complémentaire (6, 7), ensuite les écheveaux séparés (10, 11) de ces tronçons terminaux (8, 9) sont saisis à travers le tissage (2), séparés des écheveaux voisins et tirés vers l'extérieur du tissage (2).
