Patent number: 7162932Abstract: In a method for determining the radial modulus of elasticity of paper or a corresponding web-like material that can be reeled or wound on a reel, the connection between the force and deflection of a material arranged in layers is measured. The measurements of force and deflection necessary for calculating the radial modulus of elasticity are performed on a reel of paper or corresponding material outside the reeling or winding position by loading the reel with a press member.Type: GrantFiled: October 22, 2003Date of Patent: January 16, 2007Assignee: Metso Paper, Inc.Inventor: Marko Jorkama

Patent number: 7151715Abstract: A method and an apparatus (1) are used to detect the position of the edge (2) of a moving product web (3). The apparatus (1) has piezoelectric elements (5), which firstly output ultrasonic pulses (10) and secondly pick them up and convert them into an electrical signal. The product web (3) is arranged between the piezoelectric elements (5) and a reflector (11) for this purpose. If the product web (3) is located in the measurement range of the piezoelectric element (5), it attenuates the ultrasonic pulses as a result of reflection or absorption during the double passage of the latter. The position of the product web edge (2) is calculated from this attenuation.Type: GrantFiled: August 13, 2004Date of Patent: December 19, 2006Assignee: Erhardt & Leimer GmbHInventors: Juergen Eisen, Wolfgang Krauth, Hang Seibold

Patent number: 7143642Abstract: A fiber testing station. Electrically conductive first fiber retaining means engage first ends of fibers, where the fibers extend in substantially one direction from the first fiber retaining means to distal second ends of the retained fibers. The first fiber retaining means are electrically isolated from the fiber testing station. First length measurement means measure first relaxed lengths of the retained fibers between the first fiber retaining means and the second ends of the retained fibers. Electrically conductive second fiber retaining means engage the second ends of the retained fibers. The second fiber retaining means are electrically isolated from the fiber testing station. Moisture measurement means take electrical measurements along the retained fibers between the first fiber retaining means and the second fiber retaining means, and thereby determine a moisture content of the retained fibers.Type: GrantFiled: July 1, 2005Date of Patent: December 5, 2006Assignee: Uster Technologies, Inc.Inventors: Preston S. Baxter, James T. Wender, Muhammad Imran Sharafat, Youe T. Chu, Joe H. Mansfield, Michael E. Galyon, Hossein M. Ghorashi

Patent number: 7128808Abstract: A method and an apparatus for identifying mapping of a paper machine by means of a mapping test. The invention comprises forming a mapping model which takes the linear and non-linear shrinkage of a paper web into account. The mapping test result is analyzed to form a non-linear shrinkage profile and a linear mapping error from it. The linear error and the non-linear shrinkage profile thus obtained are used in the mapping model.Type: GrantFiled: May 23, 2002Date of Patent: October 31, 2006Assignee: Metso Automation OyInventors: Tapio Metsälä, John Shakespeare

Patent number: 7071480Abstract: A material web attribute detection system with the material web having a first side and a second side. The system includes a radiation source located proximate to the first side of the material web and emitting radiation toward the material web, and a radiation detection array located proximate to the second side of the material web and producing a plurality of signals based on the radiation detected from the radiation source. A processor is included which utilizes the plurality of signals to determine a lateral offset and a gap size of the radiation detection array relative to the radiation source. The processor can then compensate for the radiation detection array and radiation source relative misalignment using the plurality of signals, the lateral offset and the gap size.Type: GrantFiled: June 13, 2003Date of Patent: July 4, 2006Assignee: Voith Paper Patent GmbHInventor: Pekka Typpo
