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: 5318232Abstract: A thread winder includes a revolver on which two radially spaced mandrels are disposed for supporting thread-receiving tubes. Thread is wound onto one of the tubes located in a winding position and, when that tube is filled, the thread is transferred to the other, empty tube without interrupting the thread feed, by rotating the revolver. After the filled package is moved out of the winding position, a deflecting rod is swung to deflect the thread to a position where it can be grabbed by a transferring device. Then, the deflecting rod is swung away from the thread, and the transferring device is swung out to displace the thread toward a thread catcher disposed on the empty tube (or its mandrel), whereupon the thread is severed. A thread diverter is also swung out from the transferring device to shield the empty tube from the trailing end of the severed thread extending from the filled package.Type: GrantFiled: July 2, 1992Date of Patent: June 7, 1994Assignee: Maschinenfabrik Rieter AGInventors: Peter Busenhart, Ruedi Schneeberger, Kurt Schefer, Beat Horler

Patent number: 5102060Abstract: A winding machine winds threads upon a package. The machine includes a thread change mechanism for positioning the threads relative to the package. The thread change mechanism includes a thread guide member having first and second longitudinally spaced ends. The guide member is mounted for swinging movement relative to a housing of the machine by means of two swingable levers. One end of each lever is attached adjacent the first end of the thread guide member. A servo-motor is operably connected to one of the levers for swinging the thread guide member. A power transmission operably interconnects the first and second ends of the guide member for positively transmitting a swinging motion of the first end to the second end in order to effect synchronous swinging movement of the first and second ends. A limiting device retains the guide member in a thread change position but allows the guide member to be moved past the thread change position to a thread drawing-in position.Type: GrantFiled: July 23, 1990Date of Patent: April 7, 1992Assignee: Maschinenfabrik Rieter AGInventor: Peter Busenhart

Patent number: 5033685Abstract: A yarn winding machine is equipped with transducer means (39) disposed in the area of the ends (33, 35) of the contact roll shaft (37) to monitor the pressing force of the contact roll (11) against the yarn package (9) being wound. The short paths between the sensors and the areas where the contact roll presses against the surface of the yarn path makes it possible to measure the downward pressure at the individual measurement points or as a whole. The signals can be used to control the pressing force and also to maintain the parallelism of the axes (A, B) of the spool mandrel (5) and of the contact roll (11).Type: GrantFiled: November 28, 1989Date of Patent: July 23, 1991Assignee: Maschinenfabrik Rieter, AGInventors: Peter Busenhart, Armin Wirz

Patent number: 4969607Abstract: The apparatus for introducing a yarn or the like into the yarn catch slot of an empty bobbin tube during the changeover operation from a full bobbin to an empty bobbin at an automatic yarn winder, comprises a yarn deflector, formed of sheet metal for instance, which is provided with cutouts. Each cutout serves for deflecting an associated yarn out of an imaginary plane extending through a yarn ridge. In order to ensure that the yarn, which is still arriving at the yarn ridge of the full bobbin during the changeover operation can be infed within the imaginary plane through the yarn ridge and at the same time can extend in the plane through the yarn catch slot, the yarn is pulled by a displaceable yarn entrainment member over a curved portion of the associated cutout and deviated or deflected at the associated yarn entrainment hook.Type: GrantFiled: October 26, 1989Date of Patent: November 13, 1990Assignee: Rieter Machine Works Ltd.Inventors: Peter Busenhart, Heinz Mutter
