Patent number: 6704969Abstract: An endlessly circulating conveying device is provided for strengthening a conveyable fiber lap. The device has first and second converging rollers for conveying the fiber lap. Each roller has an outer surface and at least the first roller is provided with profile elements on its outer surface. The rollers are for subjecting the fiber lap to a pressure when the fiber lap passes through a gap between the rollers, and strengthening the fiber lap by exerting the pressure by the converging rollers and the profile elements.Type: GrantFiled: October 1, 2002Date of Patent: March 16, 2004Assignee: Trützschler GmbH & Co. KGInventors: Gregor Eschenbruch, Armin Leder

Patent number: 6689959Abstract: A weighing device for the determination of weight of a fiber material is provided. The weighing device includes multiple weighing arms. Each of the weighing arms is pivotably supported on one end. Also, each of the weighing arms is supported on an opposite end by a weighing element. The weighing arms are configured for supporting and transporting the fiber material. The weighing element provides a signal for the determination of weight of the fiber material.Type: GrantFiled: October 19, 2001Date of Patent: February 10, 2004Assignee: Temafa Maschinenfabrik GmbHInventors: Rita Scholz, Olaf Scholz, Martin Breuer, Franz Höck, Bernhard Kohnen, Thomas Bezouska, Peter Engelhardt

Patent number: 6681450Abstract: An apparatus for regulating fiber quantities to be supplied to a carding machine. The apparatus includes a duct in which the fiber material is pneumatically advanced; a feed mechanism to advance fiber material to the duct at a variable flow rate; a regulator connected to the feed mechanism for varying the flow rate; a pressure sensor disposed in the duct; an arrangement for generating first electric signals representing actual pressure values detected by the pressure sensor; an arrangement for differentiating the first signals over time to obtain second electric signals for correcting the first electric signals to obtain third electric signals representing corrected actual pressure values; and an arrangement for applying the third signals to the regulator for varying the flow rate of the fiber material, advanced by the feed mechanism, as a function of the signals.Type: GrantFiled: May 7, 2002Date of Patent: January 27, 2004Assignee: Trutzschler GmbH & Co. KGInventors: Gerd Pferdmenges, Robert Többen

Patent number: 6647595Abstract: In order to detect and remove interfering particles, particularly trash particles, husk naps, seed remnants and the like, from textile fiber goods, a device on a carding machine, a cleaner or the like is provided across the width of the carding machine, cleaner or the like with at least one detection device, for example, a camera with an electronic evaluation device for the detection, and a downstream-connected separating device for removing the particles. A plurality of guide elements are provided across the width, which can selectively deflect the fiber goods regions containing the interfering particles to improve the effect of the separating device in a simple manner.Type: GrantFiled: July 5, 2002Date of Patent: November 18, 2003Assignee: Trützschler GmbH & Co. KGInventors: Michael Schürenkrämer, Thomas Steinert

Patent number: 6615455Abstract: A fiber opening device comprising a feed section opening into the fiber opening section. The opening section includes a cabinet with an inner chamber, a waste removal chamber and a fiber web removal unit. The inner chamber includes a doffing roll and a contaminant collecting area located above first and second opening rolls. A main roll is located beneath and between the opening rolls and a waste removal section and a fiber web removal section are located beneath the main roll. In operation, fibers delivered into the inner chamber are first acted on by primarily one of the opening rolls which creates a tumbling action in which contaminants are dislodged and deposited into the contaminant receiving area while other fibers are picked up by the second opening roll carried to and doffed onto the main roll forming a fiber web for delivery to the fiber web removal section.Type: GrantFiled: September 16, 2002Date of Patent: September 9, 2003Inventor: Akiva Pinto

Patent number: 6611994Abstract: The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.Type: GrantFiled: June 22, 2001Date of Patent: September 2, 2003Assignee: Maschinenfabrik Rieter AGInventors: Jürg Bischofberger, Götz Theodor Gresser, Olivier Wüest, Christian Sauter, Jürg Faas, Peter Artzt, Volker Jehle, Hermann Maidel

Patent number: 6584651Abstract: A carding machine includes a main carding cylinder and a doffer to which fiber material is transferred from the main carding cylinder and a fiber removing device positioned downstream of the doffer as viewed in an advancing direction of the fiber material through the carding machine. A gathering device including at least one gathering roll is disposed downstream of the doffer for effecting a negative draft on the fiber material between the doffer and the gathering roll.Type: GrantFiled: May 1, 2001Date of Patent: July 1, 2003Assignee: Trutzschler GmbH Co. KGInventors: Ferdinand Leifeld, Bernhard Rübenach

Patent number: H2105Abstract: A fiber web forming apparatus which utilizes a fiber mixing chamber which in operation receives fibers from a plurality of sources along with a chemical agent, generally a bonding agent. The mixing chamber acts to further open and blend the fibers and also to blend the chemical agent with the fibers before the forming of the fiber web.Type: GrantFiled: September 12, 2002Date of Patent: June 1, 2004Inventor: Akiva Pinto
