Abstract

A method for manufacturing a twisted yarn by a combined spinning and twisting process includes the steps of producing in at least two spinning devices individual spun yarns and guiding the spun yarns together to a first centering location positioned coaxially to the axis of the double twisting device to subject the individual spun yarns in a first yarn feeding direction to a first twist, whereby a yarn balloon is formed. Subsequently, the spun yarns are guided to a second centering location, also positioned coaxially to the axis of the double twisting device, and through the second centering location into the interior of the yarn balloon to subject the spun yarns in a second yarn feeding direction, opposite the first yarn feeding direction, to a second twist. The spun yarns are then wound onto a rotating bobbin positioned in the interior of the yarn balloon.
