Abstract: A hybrid yarn, and associated system and method of making, are provided wherein a first continuous yarn is formed as a multi-filament yarn and a second continuous yarn is formed as a crimped yarn consisting of thermoplastic fibers in a parallel thread sheet. The parallel thread sheet has a plurality of crimped continuous threads next to one another in one plane. The continuous threads are formed from as a collection of a plurality of continuous filaments.

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 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.

Abstract: An inductor core 10 is proposed for a heatable godet roll comprising a plurality of inductor core laminations 11 arranged radially in a star shape with radial sections 12 and respectively one outer axial section 13 and an inner axial section. 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: A yarn build is applied to at a constant traverse length up to a limit diameter D. In order to achieve a uniform yarn draw-off tension, even with packages of large mass and correspondingly large diameter, the traverse length is thereafter reduced as the diameter increases. In the case of a conically shaped tube, the conicity of the build is also reduced which leads to improved exploitation of volume and greater package mass for a given package radius.

Abstract: In a method and apparatus for controlling a contact pressure which a bobbin being wound with a thread exerts on a roller, the contact pressure is controlled by an adjusting device. The roller is mounted on a balance beam. The divergence of the balance beam from a desired position thereof is determined by a sensor and is converted in a controller into a correction movement of the adjusting device. The adjusting device includes a worn gear with a spindle nut and a spindle driven by a motor which is controlled by the controller. By means of the controller constructed as a control loop, it is possible to very precisely maintain the bearing pressure throughout the winding process independently of the specific weight of the bobbin.
