The invention relates to a cable splice, in which a flexible intermediate link comes into use, which is in loops or Eyes is divided, through which the untwisted strands of the rope ends pulled and braided together to form a splice.

The invention relates to a splice insert with loops for pushing through the rope strands, which is characterized in that the loops with straight Alternate pieces that form a core of the splice after splicing and one Enable splicing while maintaining the shape of the rope.

In the drawing, Fig. 1 is a plan view of the partially untwisted end of a three-wire Rope and a splice insert with five loops or loops; Fig. 2 shows the same end of the rope, its untwisted strands pulled through the eyelets of the insert and wrapped around the latter are; Fig. 3 shows both ends of the rope after they have been joined at the splice point, Figs. 4 and 5 are similar views to FIGS. 1 and 3, but show a four-wire rope and a Connector with four eyelets or loops; Fig. 6 is a view similar to Fig. 4 for Illustration of the use of a splice with six loops or grommets.

In Fig. I, 2 and 3 is with. α the rope and i, 2, 3 denote its strands or wires.

The flexible splice piece b can be made from

Wire or other suitable material made 35

his and has a suitable number of loops or eyes, in the present case five, which are denoted ^{by 5 1} to 5 ^6.

If you want to splice two rope ends according to the present invention, you first measure From each end of the rope the length required for the connection is cut, a band is placed around the relevant end And then untwists the strands to the point where they are tied.

Then take strand # 1, pull it up through the first loop b ^{1 of} the connector and pull it as far as possible. In the same way, one of the remaining strands, for example No. 2, is then pulled through the loop, but from top to bottom.

Then the strand 1 is helically wound around the connecting piece b , in the same direction and with the same number of turns as the rope, until the loop b ^{2 is} reached, through which the strand 1 is pulled upwards, as shown in Fig. 2 can be seen. Then you take strand 2 and proceed with it in the same way until you reach the loop δ ³ , through which it is pulled upwards (Fig. 2).

Finally, take the last strand 3, wrap it between 1 and 2 around the splice insert until you come to the loop M through which the strand is pulled upwards (Fig. 2).

One end of the rope is now fully tightened and you can now proceed with the other end

Claims (1)

in exactly the same way, starting from the opposite end of the flexible splice insert, the only difference being that the ends are pulled downwards instead of upwards, or by * reversing the half-finished rope end so that the strands 4 and 5 go through the loop δ ⁵ , with the strand 4 ending in the loop δ ⁴ and the strand 5 in the loop δ ³ , while the strand 6 is wrapped in a helical manner and ends in the loop δ ² . The protruding ends, as can be seen from FIG. 3, are then cut off, whereupon the splice is finished. The arrangement can be varied in terms of pulling and tearing the strands through Grinding of the insert can be modified in any way, it only depends on that one or more strands, suitably two, pulled through each loop or eyelet of the insert are such that the tension to which the rope is exposed at the ends of the connection point is; closes the loops in between and thus press in the strands lying in the loops, so that the larger the one on the rope the more securely the splice is held together. In Fig. 4 and 5, the rope α has four strands or wires, while the insert b has only four loops b ¹ to ö ⁴ instead of five. , Here two strands 1 and 3 are drawn through the loop δ ^1, pulled up and a ^'2 b down, and then wound helically and through the loop. The other two strands 2 and 4 are helically wound in the same way and pulled through the loop b ^3. Likewise, the strands 5 and 7 of the other end are ^{pulled one up and one down through the loop δ 4} , wound up helically and pulled through the loop δ ³ , and the strands 6 and 8 are wound up and put through the loop δ ² . The free ends are then cut off as before. In Fig. 6 is also a four-wire. Rope α shown, while the splice insert δ has six loops δ ¹ to δ ⁶ instead of four. In this case the strands 1 and 3 are ^{pulled up and down through the loop δ 1} , strand 1 is wound up and put through loop δ ² , while strand 3 is wound up and pulled ^{through loop δ 3.} Strands 2 and 4 are wound up and pulled ^{through the loops δ 4} and δ ^5. The other end of the rope is treated in the same way, starting from the other side of the insert, after the half-finished splice has been turned over so that the drawn strand ends hang down. It goes without saying that the invention is also applicable to ropes that have more than four strands, pulling two or more strands through each end loop of the core, such that when tension is applied to the splice, the strand ends in the intermediate ones Loops are pinched. In any case, the sequence of pulling through the strand ends can be as well as the Number of loops can be changed at will, it just depends on that the strands are helically wound in the correct order and direction; it is also recommended that at least two strands go through each loop. The splice insert is expediently made from wire; however, it can also be made from other suitable building material or a ver. binding of substances exist ... In some cases it is best to avoid making the loops the pliable Liner stretch and under the torsional tension and pressure at the ends in the Give in to the loops caused by the pull in the turns of the rope, the loops to wrap with a tape of suitable, flexible or soft material, for example with cotton thread 0. the like, connecting the ends of the wrapping with each other, in order to obtain such an endless and practically non-stretchable band.
