Abstract
A two-for-one twisting process for twisting two or more individual strands being taken off from separate feed spools or packages arranged in sequence along a common twisting axis at spaced intervals, the strands being doubled or plied together along the twisting axis in a forward take-off direction, wherein the completely plied strands passing the final feed package are deflected and returned backwardly in a rotating balloon pattern by means of at least one rotating twisting disc such that a single balloon envelops each feed package with the plied strands crossing and finally meeting the twisting axis behind each package. The process is useful for plying and twisting all types of filamentary or stranded materials.
