Publication number: 20070033780Abstract: In a texturing system with a texturing nozzle and a first drum connected thereto and a further drum, a thread is guided on the outlet side of a texturing nozzle at the circumference of a drum in the form of a strip by friction and at least in part in positive manner, so that the longitudinal speed of the strip at the circumference of the drum corresponds with the circumferential speed of the drum in the area of the guide, whereby, by means of a pressure difference in an air guidance system, the effect is achieved by pressing the strip onto the surface of the drum. Further, the thread is guided in relation to its conveying speed and packing density, by positive and friction guidance under the imposition of air, as far as an outlet point on the first drum, and is transferred onto a second drum, on which the strip is cooled, extended if appropriate, and passed on to further guide or conveying rollers, respectively.Type: ApplicationFiled: October 17, 2006Publication date: February 15, 2007Inventor: Armin Wirz

Patent number: 6543104Abstract: A nozzle for the treatment of threads is divided in the conveying direction into a conveying part, a compression section and a guiding part. The compression section, for the purpose of forming a yarn plug, includes fixedly arranged radially and axially directed lamellar. The ends of the lamellar which face the guiding part are neither in contact with each other nor with any surrounding parts of the nozzle so that fibers which are located in the gaps between the lamellar, and which radially exit the channel being formed by the lamellar can reach an inlet funnel of the guiding part or a plug guide tube respectively, without colliding with any edges.Type: GrantFiled: August 22, 2001Date of Patent: April 8, 2003Assignee: Maschinenfabrik Rieter AGInventor: Armin Wirz

Patent number: 5797551Abstract: In a filament spinning and packaging system, a winder is employed to draw filaments from the filament processing operation at a threadline tension level suited to the processing operation. The winder winds the thread into large cylindrical packages. It includes a control system which may be set to control the tension of the thread entering the outer layer of the package to a level suited to the building of a good thread package, while maintaining a different upstream threadline tension suited to the filament processing operation.Type: GrantFiled: May 23, 1996Date of Patent: August 25, 1998Assignee: Maschinenfabrik Rieter AGInventors: Armin Wirz, Peter Busenhart

Patent number: 5763859Abstract: In order to prevent transmitting vibrations which are generated by the turning of a godet to an inductor used for heating the godet, the inductor may be arranged vibration-free on bearings by a vibration damper. The vibration damper may be arranged between a carrying cylinder flange of a carrying cylinder, which accommodates the inductor, and a housing end wall. A further vibration damper ring may be provided between a centering ring, for the radial damping of the inductor, with the carrying cylinder flange being pressed against the vibration damper by screws and a pressure spring being provided between the screw and the carrying cylinder flange for pressing against the carrying cylinder flange.Type: GrantFiled: March 10, 1995Date of Patent: June 9, 1998Assignee: Maschinenfabrik Rieter AGInventors: Armin Wirz, Kurt Wetter

Patent number: 5676323Abstract: A textile machine with an apparatus for recognizing and correcting deviations of sequences of movements of an element (31) driven by a driving element (33). A device (51) acquires the arrival time (t.sub.4) of the driven element (31) and corrects the start time (t.sub.1) of the driving element (33) within a predefined time window (t.sub.1u -t.sub.1o) until the arrival time (t.sub.4) of the driven element (31) lies within a predefined time window (t.sub.2u -t.sub.2o) again.Type: GrantFiled: May 17, 1996Date of Patent: October 14, 1997Assignee: Maschinenfabrik Rieter AGInventors: Armin Wirz, Arthur Haag, Peter Busenhart, Thomas Gisel

Patent number: 5649670Abstract: The axle of a chuck for a spooling machine is mounted in a damped manner within a fixed casing. The axle is rotatably supported in bearings which, in turn, are mounted in annular carriers which are spaced from the casing by a small annular gap. The carriers are supported by resilient pins in elements which serve to mount the bearings in place. In addition, a damping liquid, such as oil, is introduced in to the gap between each carrier and the casing to damp oscillations transmitted from the axle. In one embodiment, a hollow ring filled with damping liquid may be used to center the bearing and to damp the oscillations.Type: GrantFiled: February 9, 1995Date of Patent: July 22, 1997Assignee: Rieter Machine Works, Ltd.Inventors: Armin Wirz, Peter Busenhart

Patent number: 5533686Abstract: To determine thread winding parameters for reducing the rate at which deviations from a cylindrical shape are formed in thread packages being wound, thread packages are successively formed by laying thread upon a driven rotary chuck while pressing a driven rotating contact roller against the package in a manner causing a circumferential force to be transmitted therebetween. Each package is inspected for deviations from a cylindrical shape. The generation of slippage is promoted at an interface between the contact roller and package. The amount of promoted slippage is changed between the forming of successive packages to change the rate at which the deformations are formed.Type: GrantFiled: November 15, 1993Date of Patent: July 9, 1996Assignee: Maschinenfabrik Rieter AGInventors: Armin Wirz, Peter Busenhart

Patent number: 5351374Abstract: Threads made from thermoplastic materials are textured, in that they are heated by a delivery medium in a delivery channel and conveyed through an orifice into a stuffer box where they are stuffed to form a plug. In order to maintain plug formation constant, the orifice area is monitored in a sensory manner and the measured signals are used for monitoring purposes as a measured quantity in a control loop, in which the supply of damming back medium, the conveying away speed of the plug, the position of the stuffer box walls, or the supply of delivery medium are used as manipulated variables. The measuring signals produced by monitoring can be compared with thresholds to produce control signals corresponding to the comparison result for activating alarm, warning or stopping elements.Type: GrantFiled: February 4, 1993Date of Patent: October 4, 1994Inventors: Werner Nabulon, Jorg Maier, Peter Grossenbacher, Felix Graf, Armin Wirz

Patent number: 5324905Abstract: A drawing roller unit is constructed with a godet and an electric motor mounted on a common shaft. A passage is provided throughout the unit to convey a non-flammable scavenging gas through the motor and the godet to reduce the risk of explosion due to sparking by the electric motor and/or other electrical parts of the drawing roller. The gas introduced can leave the unit only through a narrow gap. The pressure of the gas is consequently above atmosphere pressure and prevents the entrance of air.Type: GrantFiled: April 26, 1991Date of Patent: June 28, 1994Assignee: Rieter Machine Works, Ltd.Inventors: Vittorino Arnosti, Rolf Widmer, Konrad Boos, Armin Wirz

Patent number: 5159166Abstract: The drawroll unit has a heatable galette in which the shaft of the gallette is mounted in bearings which, in turn, are mounted via vibration damping devices in a stationary housing. The vibration damping devices may be in the form of bodies of interlaced wire, O-rings or the like. The vibration damping devices serve to damp vibrations of the shaft in a critical speed range within the normal speed range of the rotor so that the galette can be operated at any speed within the normal speed range.Type: GrantFiled: June 28, 1989Date of Patent: October 27, 1992Assignee: Rieter Machine Works, Ltd.Inventors: Vittorino Arnosti, Konrad Boos, Bruno Gemperle, Felix Graf, Rodolf Leinhard, Emil Munz, Richard Rollin, Rolf Widmer, Armin Wirz
