摘要： A shedding device in a jacquard weaving machine, comprising a retracting (14) spring in order to form a lower compartment, for example, said retracting spring being firmly anchored on one end thereof in the weaving machine or on the floor. In order to suppress resonance formation in said spring (14), a core element (22) is provided, said core element being disposed in an adjacent position with respect to the inside of the spring (14) at distanced points thereof and imposing a travel on said spring (14) which deviates from the straight progression thereof, thereby creating friction forces between the spring (14) and the core element which are used to dampen the movement (14) of the spring.

摘要： A yarn-twisting device (10) for twisting multifilament yarns comprises a yarn channel (20) and yarn guides (15, 16) arranged at a certain distance from the inlet and outlet of the yarn channel so as to press the yarn against the yarn channel when the compressed air supply is interrupted in such a way that the yarn in the yarn channel runs parallel to the longitudinal direction of the latter and the straight sections of yarn between the inlet and outlet of the yarn channel and the yarn guides form an acute angle with the sections of the geometrical longitudinal axis of the yarn channel (20) located outside the yarn channel. In addition, the blowing angle of the blower nozzle is less than 90°. The maximum length of the yarn channel (20) is 40 mm for smooth yarns and 30 mm for textured yarns. The maximum distance between the yarn guides (15, 16) and the yarn channel (20) is 30 mm. Very high yarn feed speeds and excellent twisting of the yarn are achieved.

摘要： The invention relates to a method for the production of a double- or multi-component multifilament yarn, the components of which comprise differing shrinkage properties, whereby at least one component irreversibly lengthens on the action of heat. The yarn components are each produced loop-free in a continuous manner as a straight yarn and then combined to give a combination yarn. The ready-to-use, loop-free combination yarn is wound on a spool for further use. The length change property may be initiated by means of a heat treatment after processing to give a textile fabric. The device comprises a collector for each component, followed by parallel working processing devices for the separate processing of each of the components. The processing device for the extending component comprises a drawing field formed by drawing rollers and a staged heating. The processing device for the shrinking components has a drawing field formed by drawing rollers. A delivery device for collating the components is provided, also a connecting device and a winding device.

摘要： The inventive device for intermingling multifilament yarns has a yarn channel in which the filaments of the multifilament yarn can be intermingled by means of a flow of medium emerging from an opening cross-section of a blast nozzle arrangement, especially flows of pressurised air. The opening cross-section of the blast nozzle arrangement is essentially symmetrical to the longitudinal axis of the yarn channel. A particular blast nozzle arrangement (35) divides the flow of medium into a main flow and pairs of secondary flows. The main flow flows into the middle area (29) of the yarn channel (13), one of the secondary flows flows into one edge area (33) and the other secondary flow flows into the other edge area (33) of the yarn channel (13). The main (H) and secondary (N) flows are essentially oriented in the same direction.

摘要： The invention relates to a woven fabric, in which at least one of the intersecting yarn systems contains a differential shrinking yarn (C), which consists of at least one decorative component (A) that elongates irreversibly during thermal treatment and at least one shrinking component (B), which contracts during thermal treatment. The components (A) and (B) are interconnected by means of entangled knots. The number of entangled knots per metre of yarn (C) in the finished woven fabric corresponds to the number of yarns in the intersecting yarn system. The woven fabric is produced in such a way that the components of the differential shrinking yarn are interconnected by air entanglement and in the finished woven fabric contain Ymin>98+0.7x entangled knots. After the entanglement process, the unsized yarns are interwoven as a warp with a weft in such a way that the number of weft yarns in the finished woven fabric is (X). The woven fabric obtained in this manner is subsequently thermally treated.

摘要： The invention concerns a method as well as a device for checking, during the swirling process, swirled-filament yarns with regard to their swirl intensity, or for unacceptably long unswirled or insufficiently swirled lengths of yarn. The invention calls for vibrational measurements to be made on the yarn (8) in the vicinity of the swirling device (1) and the measurements to be processed to provide the check.
