Abstract: A thread guide engages the thread from a supply qallet to a suction element, while the thread is held by the suction element, to entrain the thread to the thread-capturing slit of a winding sleeve in a winding apparatus, especially a stretch winder. As a result, the thread meets the winding sleeve at a location at which the winding sleeve and the thread are traveling in the same direction.

Abstract: A device for moving a thread to a winding sleeve driven by a friction wheel, especially in a stretch-winding machine, has a tubular portion adjacent the mouth into which the thread is drawn by suction and which is provided with at least one blade to sever the thread with a minimum tension applied thereto. That keep the loose ends as short as possible.

Abstract: An apparatus for producing thick/thin effects in a filament yarn, whereby between inlet and outlet gallets or pairs of pinch rollers, in a stretching zone, the filament yarn contacts the periphery of at least one rotating disk which is heated and is formed with at least one region of reduced radius in which there is no contact between the filament yarn and the disk. The filament yarn is thereby stretched only in regions in which it is heated by contact with the disk periphery and remains thick in those regions in which it is unheated because of the presence of the recess.

Abstract: A thick/thin and/or color effect composite yarn is produced by depositing a sheath of one or more effect threads on a thick/thin filament yarn in which the thick regions are incompletely stretched, and the resulting assembly is then subjected to stretching to full stretch-out thicker regions.

Abstract: A method of and apparatus for producing a thin/thick effect yarn provides a thin/thick effect by segmentwise stretching of a filamentary precursor yarn which is combined with a fully-stretched filamentary precursor yarn so that the latter supports the former. The combination can be effected by twisting, nub entanglement or winding of one yarn around the other.

Abstract: The invention relates to an articulated pipe connection for two conducting arts of a motor vehicle which comprises spherical connecting pieces for joining the two conducting parts and has at least on one connecting piece a flange-shaped connecting piece abuttable axially against the latter, said connecting piece being connected with spring tension by spring means with the other connecting piece, with the connecting pieces being held together by the spring means with a pretensioning force.

Abstract: The distribution of thick regions along a filament yarn can have a random character if the thick regions of a filament from a first stretching zone are heated in a second stretching zone and thereby permitted to stretch and reduce in thickness. The heating in the second zone is out of phase with the thick regions of the first stretching zone.

Abstract: A heated galette is provided with a heating unit and a temperature sensor connected in a control circuit with the heating unit to maintain a certain temperature of the surface of the galette on which a synthetic yarn is guided. The control circuit is disconnected periodically or intermittently so that the heating unit can be heated independently of the feedback control provided by the control unit. Upon the heating unit attaining an equilibrium with temperature, a first actual value temperature is measured and a difference is obtained from a setpoint temperature corresponding to a given control ratio and a signal representing the difference is generated. Utilizing this system, it is possible to detect failure of the temperature sensor and/or the heating unit or inappropriate positioning of the temperature sensor.

Abstract: An apparatus for winding a synthetic-resin yarn on a spool of predetermined outside diameter has a friction drive roller rotatable about a drive axis and having a substantially cylindrical outer surface of predetermined length centered on the drive axis. A drive can rotate this roller about the drive axis at a substantially constant speed. A support adjacent the friction roller holds the spool for rotation about a spool axis generally parallel to the drive axis and with the spool in radial contact with the surface of the drive roller. A radially outwardly projecting ridge carried on the support axially offset from the surface of the friction roller is of greater outside diameter than the spool. Guides feed the yarn initially to the ridge for winding of the yarn thereon and thereafter for feeding the yarn to the spool for winding of the yarn on the spool.

Abstract: In a textile-processing operation wherein a filament is displaced longitudinally continuously past a treatment station and a liquid is applied to the moving filament at the station, a supply of the liquid is held in a container spaced from the station and connected via a conduit to an applicator at the station. Space above the liquid in the container is filled with a gas that is devoid of free oxygen and that is in direct contact with the liquid. This gas above the liquid is pressurized in the container to controlledly force the liquid from the container through the conduit to the applicator at the station. The liquid is kept out of contact with oxygen until it actually has been applied to the filament. In fact the filament is passed over a small-diameter orifice formed in a guide and the liquid is forced from the orifice. The filament directly engages the guide at the orifice and covers the orifice so that the liquid does not contact the ambient air until after it is applied to the filament.

Abstract: A texturizing machine for false-twist crimping of synthetic yarns having a plurality of work stations at each of which yarn is drawn by feed rolls from supply bobbins and guided successively through a heating device, a cooling device and a texturizing unit to a group of superjacent bobbin winding units, with the bobbin winding unit groups being arranged in longitudinal succession along the length of the machine. A pair of opposed spaced longitudinaly extending support frames define an operator service passageway therebetween. The heating devices, cooling devices and texturizing units are disposed adjacent the passageway with the yarn being guided over the passageway. The bobbin winding units are mounted on the opposed frames on both sides of the passageway with the groups of bobbin winding units alternately mounted successively on opposite frames longitudinally of the machine with the yarns of successive bobbin winding unit groups being guided in opposite directions over the passageway.

Abstract: A high speed yarn winding device performing a parallel winding, with the winding having yarn windings which intersect within each winding layer. The parallel winding is formed on a sleeve rotatably and interchangeably mounted on a carrying device through a driven friction roller. The friction roller is partially looped by the yarn to be wound on and a yarn winding body involved in a winding of the yarn abuts at its outer circumference with the friction roller. A guide bar is adapted to execute lifting movements parallel to an axis of rotation of the friction roller, with the bar carrying a rotatably mounted wheel driven by the yarn fed to it and coming in contact with it and superimposing much more rapid and shorter modulating strokes on the relatively slow lifting movements of the guide bar. To improve the winding conditions of the yarn and the composition of the parallel winding, the wheel has at least one round drive surface concentric to the axis of rotation.

Abstract: A false twisting machine which includes a frame having racks of thread supply spools on opposite sides with centrally disposed bobbin supporting take-up mechanisms therebetween defining corridors on opposite sides thereof with thread heaters and false twisting members disposed horizontally across the top of the machine, together with thread transport mechanisms for stretching the threads and for advancing the threads vertically upward from the thread supply spools on opposite sides of the machine across the top of the machine in a horizontal path with virtually no deviation therefrom through the heaters and false twisters and then downwardly onto the take-up bobbins for ultimate removal of the wound thread packages from the machine thereby providing a machine of greatly reduced height and capable of easy maintenance.
