Abstract: A winding device and associated method for swiveling a bobbin in the winding device during an interruption of a winding operation are provided, wherein the bobbin rests on a backing roller and is formed on a bobbin tube onto which a thread is wound. The bobbin tube is rotatably held between holders on two retaining arms mounted on a common swivel arm having a swivel axis. With force measurement unit, one of intrinsic weight of the bobbin or a force effect that acts on the retaining arms due to contact of the bobbin with the backing roller is measured. A manual force is transmitted into at least one of the retaining arms in a force direction that is determined by evaluating the force measurement unit. With a drive that is operably configured with the swivel arm, the swivel arm is swiveled in the force direction.

Abstract: A method for adapting a travel end position of a changing movement of a thread to a flange spool includes means of which the thread is moved back and forth during a spooling operation along a rotation axis of the flange spool relative to the flange spool by means of a changing thread guide. The flange-side travel end position can be moved away from the flange of the flange spool in an axial direction when the thread tension decreases when the thread is moved away from the flange-side travel end position. Also, the flange-side travel end position can be moved by means of the changing thread guide in an axial direction towards a flange of the flange spool when the thread tension increases when the thread is moved away from the flange-side travel end position. Included is a spooling device for carrying out the disclosed method.

Abstract: A thread displacement device for displacing a thread on a winding body includes a thread guide, which, depending on a movement of the winding body, can be freely selectively moved back and forth along a curved path defined by guide means. The thread guide has a thread guide roller rotatably mounted about a thread guide roller rotational axis to guide and press the thread against the winding body, said thread guide roller being configured as a self-directing roller. The guide means includes a flexibly deformable traction means, which can be guided back and forth via deflection rollers and/or deflection rods and on which the thread guide is directly fastened.

Abstract: A housing 1 for enclosing a nozzle is suggested, particularly an air covering nozzle or an air texturing nozzle 3, with at least one filament pass-through aperture 10, 11, 12, 13 having a filament pass-through aperture circumference 20 and a housing cover 5 that covers a housing opening in a housing base 15, housing cover 5 engaging with housing base ridges 18 on housing base 5 by means of cover ridges 17, filament pass-through aperture 10, 11, 12, 13 being located in such manner on one of the housing base ridges 18 that part of filament pass-through aperture circumference 20 is formed by one of the cover ridges 17.

The inductor core 10 has end plates 19, 20 with respectively one surface 21 complementary to the radial sections 12 and fixing means, wherein the inductor core laminations 11 are arranged between the end plates 19, 20 and wherein the fixing means 22 are set up to fix the inductor core laminations 11 at their radiation sections 12 on the end plates 19, 20 or alternatively and/or on the outer surface of an inner tube.

Abstract: A yarn quality assurance method and a yarn processing machine set up for implementing the method according to the invention is proposed comprising at least one feeding spool receiver 24, 30 set up to receive respectively at least one feeding spool 20, 29 from which yarns can be taken off, and a multifilament yarn manufacturing unit 5 to which yarns are supplied from the feeding spools 20, 29 via thread runs with respectively one thread tension. According to the invention, a thread tension regulating module 25 with a thread tension sensor is arranged in at least one controlled thread run 1 between the relevant feeding spool receiver 24 and the multifilament yarn manufacturing unit 5, wherein the thread tension regulating module 25 is set up to derive a control value from a thread tension measured by the thread tension sensor and to keep the thread tension constant in a predetermined thread tension range.

Abstract: The device serves to produce effect yarns on process machines through the deliberate production of short lumps in the yarn through short-duration yarn overfeed and includes a device (A) for lateral yarn deflection which comprises a motor-driveable, servo-controlled yarn guide (3) with an adjustable stroke. A movement of the yarn guide (3) in the one direction effects a slight underfeed and a movement in the other direction effects a pronounced overfeed of the yarn (F, F2). The yarn guide (3) is attached to a traverse-motion element (2), formed by a flexible member which is rigid in the stroke direction, preferably by a wire rope, a string or a belt, by which it is driven. The yarn guide (3) effects the storage of a yarn length, in the form of a loop, which corresponds to the desired overfeed. The device is used in false-twist and air texturing machines.

Abstract: An apparatus for winding a thread onto a bobbin having a traversing element susceptible to tension variations and a thread guide for executing a traversing motion along the longitudinal direction of the bobbin. The thread guide is connected to the traversing element, which is operated by a plurality of guiding elements and a drive wheel arranged to function as a pre-loading element. By virtue of the drive wheel functioning as a pre-loading element, tension variations in the traversing element are absorbed when the direction of the traversing element is reversed. This allows the winding apparatus to achieve very high traversing speeds and thread guide positioning accuracies.

Abstract: An apparatus for winding a yarn onto a bobbin wherein the apparatus includes: a finger-shaped yarn guide supported along a first axis orientated at right angles to the bobbin axis, the yarn guide being subject to an oscillating motion about the first axis; and energy storage mechanisms for controlling the deceleration and acceleration of the yarn guide in short regions near reversing points for the yarn guide motion, wherein the position of the energy storage mechanisms is adjustable.
