Device and Method for Producing a Load Bearing Cable, as well as a Load Bearing Cable
A device 100 produces an endless winding cable 101 by winding a yarn 106 around two thimbles 102, 104. The device 100 comprises an elongated guide 110, a carriage 112, a yarn feeder 114, a first thimble holder 116, and a second thimble holder 118. The first thimble holder 116 and the second thimble holder 118 each hold one of the two thimbles 102, 104. The carriage 112 is movable relative to the elongated guide 110. The yarn feeder 114 is connected to the carriage 112, and comprises at least one spool holder 120 for holding a spool 122 with the at least one yarn 106, and an output guide 124 for guiding the at least one yarn 106 to the cable during winding. The yarn feeder 114 comprises at least one yarn brake 126 for controlling a tension of the at least one yarn 106 during winding.
Low slip splice
A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.
Rope having a spliced eye, corresponding method of forming an eye and use of the rope
Rope having an eye. The rope comprises a first rope portion and a second rope portion. The first rope portion and the second rope portion are spliced into each other for forming a spliced connection for obtaining the eye. The first rope portion and the second rope portion are formed from an end portion of the rope.

Wire puller and cord
A cord and a wire puller are used to pass through narrow pipes or the like. The cord includes a first guide wire section and a second guide wire section. The first guide wire section includes a plurality of first guide wires, and the first guide wire section has a first segment in which the first guide wires are intertwisted with each other. At least a part of the first guide wires extends from the first segment to a transitional segment. The second guide wire section includes a plurality of second guide wires, and the second guide wire section has a second segment in which the second guide wires are intertwisted with each other. At least a part of the second guide wires extends from the second segment to the transitional segment, in which the first and second guide wires are intertwisted with each other.
SPLICED ROPE SYSTEM
The present invention is related to a rope system (10, 20) comprising a first rope section (14, 24), a second rope section (16, 26) and a splice structure (12, 22), wherein the first and the second rope section comprise each at least 3 rope strands. Wherein said splice structure (12, 22) is between the first rope section (14, 24) and the second rope section (16, 26) and connects said first to said second rope section, wherein the rope system further comprises at least one conductive element (18, 28) extending from within the first rope section through the splice structure into the second rope section, whereby at least a portion of the conductive element is immobilized in both, the first and second rope section.
YARN DELIVERY DEVICE FOR A TWISTING OR CABLING MACHINE
Yarn delivery device for a twisting or cabling machine, for feeding a yarn via a traversing yarn guide to a take-up package, the yarn delivery device having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of the second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, the second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection roller to receive the yarn from separator roller or godet and to deflect the yarn toward third deflection roller.
