Method and apparatus for the layerwise SZ-stranding of elements to be stranded about a flexible core strand

A method for the layerwise stranding of elements to be stranded, especially of elements of electric cables, about a flexible core strand, in which the elements to be stranded continuously run off from stationary supplies and are temporarily run concentrically to the core strand which is held stretched, whereby stranding lays are stored, and in which the elements to be stranded are subsequently guided around the core strand in directions alternating at intervals and in the process are cabled onto the core strand, which is guided in a manner secure against torsion, with a definite length of lay and with alternating direction of lay, comprising, for the purpose of temporary storage of stranding lays, the elements to be stranded

• (a) first temporarily cabling the elements to be stranded onto the core strand with a direction of lay alternating at intervals by means of torsioning the core strand;
• (b) roping down the elements from the core strand by leading the elements to be stranded around the core strand synchronously with the final stranding;
• and
• (c) then feeding the elements spaced from and parallel to the core strand, which is conducted freely torsionable, or to the stranding axis, respectively, to the final cabling operation.
