Document Type and Number:
Japanese Patent JP2005535875
Kind Code:
A
Abstract:
An apparatus for a papermaking machine, comprises an active airfoil (32) having a wall defining a web-supporting surface (44) adjacent to which a paper web travels in the papermaking machine, the wall defining openings (49) through which air is discharged to form an air layer along the web-supporting surface for supporting and stabilizing the paper web; and a measuring device (60) integrated into the active airfoil and directed from the web-supporting surface onto the paper web for measuring at least one property of the paper web, the measuring device being operable to measure the web property from only one side of the web. According to the invention said measuring device (60) is a non-traversing measuring device that is arranged to measure said at least one property at a plurality of locations spaced along the paper web.
