The invention relates to the manufacture with reference to the drawing explained, which shows a

of wire strands made up of two to six individual wires. schematic view of the wire rope device

As already mentioned, the wires are preferably guided in a sinusoidal path.

are shown, to a take-up reel 14, which is attached with its axes at right angles to the incoming strand so that there is no winding twist.

An apparatus for performing the method according to the invention only requires a supply reel spindle to create strands from two to six wires. This upper limit applies because because with a larger number of wires, if a special twist is not used, at least one of the wires must be shorter than the other. However, this requirement cannot be met, when the wires are wound together in groups on a single spool.

Two or more metal wire strands which have been produced by the method according to the invention can be twisted into a stronger strand and z. B. to reinforce rubber objects, such as vehicle tires.

Claims (4)

Patent claims: 1. Method of making a metal wire strand from two to six individual wires, the wires being unwound from a single spool and are twisted together to form a strand, characterized in that the wires as a twisted wire group (3) 'are wound onto the spool (1) beforehand, then at the' Unwinding the wires as a group and leaving the group of wires a real twist is issued, the wires then by false-twist distribution up to the permanently deformable Area to be stretched and finally the finished strand is wound up. 2. The method according to claim 1, characterized in that the individual wires during winding twisted together on the spool (1). 3. The method according to claim 1 and 2, characterized in that the wire group (3) when Unwinding from the spool (1) to form a balloon known from two-for-one twisting spindles a double twist is given. 4. The method according to claim 1 to 3, characterized in that the finished stranded wire without rotation distribution is wound up. 1 sheet of drawings
