ABSTRACT:
A method of manufacturing collectively stranded wires for communication cables, comprising a process wherein parallel multi-wire sets obtained by the extrusion method from insulating material and a plurality (2, 3 or 4) of conductor wires arranged in parallel are prepared in such a way that said multi-wire sets are different in color from each other and the number thereof corresponds to that of the conductor wires included in each thereof, and said multi-wire sets are drawn out and separated into element wires which are, after given pre-twisting, sorted into groups each consisting of wires of different colors coming from the corresponding sets and then are wound on bobbins, a process in which said bobbins prepared according to desired number of stranded wires to be collected are mounted on delivery stations of stranding machines through which the wires are stranded and sent out as pairs, 3-conductor or 4-conductor wires, and a process wherein desired number of said stranded wires are collected.
