  • Patent number: 11220786
    Abstract: A traversable measuring device (15) for determining a cross direction profile of a property of a moving lignocellulose-containing fiber web (2). The measuring device has a property measuring sensor (23) for determining a measurement result representing the property of the web at multiple cross directional measurement positions (P1, P2, P3, P4), a position measuring sensor (24) for determining the cross directional measurement position of the property measuring sensor associating to the respective measurement result, and an analysis device (25) for receiving the measurement results and the respective cross directional measurement positions (P1, P2, P3, P4) and for allocating the measurement results with the respective cross directional measurement positions for forming the cross direction profile of the web property (2). The measuring device has a mounting bracket (16) that is detachably fixable with quick clamping for fastening the measuring device at a measurement site in a fiber web machine (1).

  • Patent number: 10697119
    Abstract: An arrangement and method for monitoring a Yankee cylinder (3). The arrangement comprises a Yankee cylinder (3) arranged in a tissue machine (1) for manufacturing a tissue web (2), a measuring device (10) being a permanent part of the tissue machine (1) and providing a main measuring device for a process control of the tissue machine (1), and at least one data processing unit (15) configured to process measurement data describing the at least one measured property of the moving web (2). The data processing unit (15) is configured to form at least one graphical representation describing a treatment effect performance provided by a heated outer surface (4) of the Yankee cylinder (3) to the web (2) to be manufactured.
