Patent number: 7802377Abstract: The invention relates to a drying cylinder which is used to dry a paper, cardboard, tissue or other web of fibrous material in a machine for the production and/or for the transformation thereof. The drying cylinder includes a support body and an external cover layer which is heated by a hot fluid. The thermal flow passing through the external cover layer is increased such that at least one cavity is provided between the support body and the external cover layer through which the fluid flows. The external cover layer is predominately so thin that the ratio formed by the thermal conductivity of the material and the thickness of the external cover layer is greater than a threshold value of 3.2 kW/m2K for steel, 30 kW/m2K for aluminum, 18 kW/m2K for bronze alloys, 3.4 kW/m2K for copper and 6.1 kW/m2K for magnesium.Type: GrantFiled: June 28, 2007Date of Patent: September 28, 2010Assignee: Voith Patent GmbHInventors: Rainer Kloibhofer, Christoph Haase, Thomas Gruber-Nadlinger, Herbert Boden, Erich Rollenitz, Manfred Gloser

Patent number: 7721519Abstract: A method which improves the correspondence between the produced fancy yarn and the predetermined configuration of said fancy yarn. The fancy yarn is guided through a sensor device in a spinning device after it is formed and the diameter of the fancy yarn is continuously measured by the sensor device. The fancy configuration of the produced yarn is determined on the basis of the measured values of the diameter and is compared with the predetermined fancy configuration. The comparison is carried out until sufficient correspondence between the predetermined fancy configuration and the fancy configuration of the optimized, produced yarn is achieved.Type: GrantFiled: December 29, 2004Date of Patent: May 25, 2010Assignee: Oerlikon Textile GmbH & Co.

Publication number: 20090134193Abstract: An arrangement for handling a paper, cardboard, tissue or other fibrous-material web in a machine for producing and/or finishing the same, includes an endlessly circulating belt of high flexural rigidity which wraps around a rotatably mounted control roller with an angle of wrap, wherein at least one end of the control roller is displaceably mounted along an adjusting zone for setting the belt tension. The arrangement of the present invention provides an improved running of the belt and the lateral stress of the belt is minimized by the angle of wrap lying between 90° and 180° and the adjusting direction of the control roller lying approximately perpendicular to the bisector of the angle of wrap.Type: ApplicationFiled: November 21, 2008Publication date: May 28, 2009Inventors: Anton Pirko, Martin Egger, Christoph Haase

Patent number: 7510086Abstract: This invention relates to an arrangement for sealing off a fluid-filled, stationary pressurized compartment from an endlessly circulating, impermeable belt of a machine for producing and/or refining a paper, paperboard, tissue or other fibrous web with the help of at least one seal of the pressurized compartment, whose contact pressure toward the belt is variable, wherein the belt is pressed by the pressurized compartment against a co-driven support element and the fibrous web runs alone or jointly with one or more function belts between the belt and the support element. The sealing is improved in this case, while producing as little leakage and wear as possible, in that the contact pressure of the seal is controlled as a factor of the drive power and/or the drive torque channeled into the belt and/or as a factor of the leakage of fluid through the gap between the seal and the belt and/or as a factor of the pressure of the fluid in the pressurized compartment.Type: GrantFiled: December 1, 2006Date of Patent: March 31, 2009Inventors: Joachim Henssler, Christoph Haase, Herbert Boden, Helena Johansson

Patent number: 7464531Abstract: A method for visually displaying the maintaining of specified effects in a produced fancy yarn by measuring the deviations of the yarn diameter from the desired specifications. The display is a two-dimensional classifying matrix which is known per se. The display matrix is divided into longitudinal regions in one dimension and diameter regions in the other dimension, and forms a class in each case by combining a longitudinal region with a diameter region, wherein each deviation from the desired specification is allocated to a class. Only the effect regions of a fancy yarn are included in the classifying matrix, with only the regions of the fancy yarn counting as effect regions, the diameter of which is at least a specified amount over a specified web diameter and the length of which exceeds a specified minimum length.Type: GrantFiled: September 10, 2004Date of Patent: December 16, 2008Assignee: Oerlikon Textile GmbH & Co.

Patent number: 7454889Abstract: A method for producing an effect yarn on an open-end rotor spinning machine, formed from an alternating line-up of yarn sections and effects consisting of pre-determined thickenings, wherein an effect is produced where the yarn is joined by means of a piecing end, in the piecing region of the yarn located downstream of the piecing end, following a break in the thread. The quality of the yarn produced in this way is improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piecing regions, are eliminated.Type: GrantFiled: October 13, 2004Date of Patent: November 25, 2008Assignee: Oerlikon Textile GmbH & Co.

Publication number: 20070137165Abstract: The aim of the invention is to create a method that allows a previously produced fancy yarn to be reproduced. Said aim is achieved by a method in which a model fancy yarn is first guided through a sensor device for measuring purposes, the diameter of the model fancy yarn is continuously measured using the sensor device, the measured diameter values are evaluated, and the formation of the effect of the model fancy yarn is determined therefrom. Spinning settings are generated from the data representing the formation of the effect, and said spinning settings, which are based on the set of data, are used for producing a fancy yarn.Type: ApplicationFiled: October 13, 2004Publication date: June 21, 2007Applicant: Saurer GmbH & Co.
