Abstract: A yarn treatment chamber for thermal treatment of a running yarn, with a center zone, in which a pressurized hot, gaseous or vaporous medium acts on the yarn, and end zones on both sides of the center zone, in which a cooling, gaseous medium is active. The end zones have a yarn inlet or outlet openings with a yarn sluice, which seals the associated end zone and the yarn treatment chamber. The yarn inlet and outlet openings (2, 3) are arranged such that the yarn (14) must change direction, and the yarn treatment chamber (21 has yarn deflection means (12) to guide the yarn (14) between the yarn inlet and outlet openings (2, 3). Both the yarn sluice (23A) and the yarn sluice (23B) are accessible without problems to operating staff at an ergonomically favorable height below the yarn deflection means (12) of the yarn treatment chamber (21).

Abstract: A yarn sluice for sealing a pressurized yarn treating chamber in which a traveling yarn is thermally treated, comprises yarn guide elements in the region of a yarn inlet and outlet openings of the treating chamber forming a yarn guide channel sealed by the traveling yarn during operation. At least one of the guide elements is positionable for adaptation to the mean thickness of the traveling yarn in various predetermined positions. Means is provided for temporary adaptation of the yarn guide channel to yarn defects. At least one of the guide elements (26, 27) is steplessly adjustably mounted for adaption to the mean thickness of the traveling yarn (14). A sealing element (28), which can be placed on the first and the second yarn guide element (26, 27), extends along the yarn guide channel (25), for closing it and for reacting resiliently to defects in the traveling yarn (14).

Abstract: Method for thermal treatment of a running yarn (14) on a multi-workstation twisting machine, each station having a device (1) for thermal treatment of the yarn, and a delivery system (2, 3) preceding or following such device (1). The yarn (14) passes through the device (1) substantially without tension, and after passing the downstream delivery system (3), is wound. The yarn (14) is loaded with a defined force by position-variable means (24, 25, 27). Position changes of such means caused by a change in the yarn tension under disruptive influences during the thermal treatment of the yarn (14) are used as a control variable for controlling at least one of the delivery systems (2, 3).

Abstract: A process for treating a yarn with a gas- or steam-creating medium includes traveling the yarn between a pair of elongate yarn guide elements in a pressure chamber portion of a yarn treatment chamber that is substantially sealed off to the environment and is under an overpressure. The process further includes drawing the yarn through an additional yarn guide element. The cross section of the one pair of elongate yarn guide elements and the cross section of the additional yarn guide element correspond to the thickness (titer) of the yarn traveling through these yarn guide elements such that the yarn travels through these yarn guide elements in a substantially friction-free manner and the one pair of elongate yarn guide elements and the additional yarn guide element operate in cooperation with the yarn treatment chamber such that the yarn treatment chamber is substantially sealed off against loss of pressure.

Abstract: A device for treatment of a traveling yarn with a steam-creating medium includes a column of several chambers provided with yarn inlet- and yarn outlet-channels and arranged one over the other, of which one of the chambers is a steam treatment chamber provided with a steam inlet and a condensate outlet with respect to which mixing chambers are respectively operated upstream and downstream thereof, with each such mixing chamber respectively having an air inlet and a condensate outlet. The yarn inlet- and yarn outlet-channels have an opening cross section that, on the one hand, makes possible a pneumatic yarn threading-in and, on the other hand, controls the exchange of air and steam between the chambers such that a steam-air-mixture atmosphere sets in that substantially forecloses the entrance of air into the steam treatment chamber.

Abstract: A method for spinning fibers onto the free ends of the two threads of a yarn that is produced during an integrated spinning and twisting process and a two-for-one spinning and twisting apparatus for performing the method are provided. The method includes gripping a twisted yarn, separating two threads of the twisted yarn in a manner such that the twist which was originally present in each individual thread prior to the doubling of the thread with the other thread returns to the now separated thread portion, and forming a thread loop of each separated thread portion. Each thread loop is clamped and respective portions of the two branches of the thread loop extend to a spinning rotor and the spindle hollow axle. Spinning is commenced in coordination with winding and the thread loop is dissolved as the now joined thread is drawn into the spindle hollow axle.
