摘要： 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.

摘要： A device for producing a twisted yarn by an integrated or combined spinning and twisting process is provided and comprises a two-for-one twisting spindle with at least two spinning rotors, positioned within the yarn balloon produced by the twisting process, for producing the individual yarns to be twisted, into which spinning rotors the disentangled fiber material is supplied respectively by the fiber supply tubes, which are connected to the fiber material disentangling units. The fiber material disentangling units are combined to a single fiber material disentangling apparatus with common drive elements for the two disentangling units. The fiber material disentangling apparatus is arranged at least partially below the two-for-one twisting spindle so that the individual spindles can be arranged relatively closely adjacent to one another, wherein each fiber supply tube follows over a portion of its length a circular arc wherein the angle a of directional change to the radius of curvature (r) of the central line of the tube has a ratio of &agr;/r=2.5 to 3.5.

摘要： In a method for producing a twisted yarn by an integrated spinning and twisting process, individual spun yarns are spun from loose fiber material in at least two spinning devices. The spun yarns are combined and guided in a first direction and subjected to a common first twisting to form a once twisted yarn. The once twisted yarn is then guided in a second direction opposite the first direction according to the two-for-one twisting principle, to form a yarn balloon in order to subject the once twisted yarn to a second twisting. The resulting yarn is then fed through a centering point to a winding device. The loose fiber material is fed into the annular chamber, that is coaxial to the yarn balloon and in which the yarn balloon freely rotates, and is guided substantially radially through the yarn balloon such that the yarn of the yarn balloon directly passes through the loose fiber material. The loose fiber material is then conveyed from the annular chamber substantially radially inwardly into the spinning devices by a pressure gradient.
