QUALITY MEASURING METHOD AND QUALITY MEASURING DEVICE FOR LONG SHEET MATERIAL
[Problem] To provide a quality measuring system that can measure the quality of a paper web by separating a flow direction component and a width direction component, that is of a non-scanning and non-filtering method which does not require a conventional basis weight sensor or ash meter using radiation or X-rays, that can be applied from small low-speed paper machines to large high-speed paper machines, and that involves a stable online accuracy confirmation method and correction method for long materials with high cost efficiency. [Solution] In a quality measurement method for a long sheet material W, cellulose fiber, moisture, ash, etc., of a paper web W are measured with area cameras 1102-1106 each having an infrared light receiving element and a light source 1100 having an infrared light emitting LED element. The performance confirmation of the infrared cameras 1102-1106 over the entire width and the correction of the measurement values are performed by using the consistency of the same point measurement values by the adjacent cameras in the overlap area and a comparison sample 1107 at the off-sheet positions provided at both ends.

The invention relates to a synchronizing method of a web inspection system comprising a synchronizing device and at least one slave camera and lighting device arranged to illuminate an area of the web. The method comprises transmitting a synchronizing signal to the at least one slave camera, and wherein all the cameras are configured to be synchronized with each other, transmitting a light synchronizing signal to the at least one lighting device indicating a switching on and off times, which switching off time corresponds to the synchronization moment, and calculating a starting time of integration based on an individual integration time of a camera and the synchronization moment. The invention further relates to a web inspection system and computer program product causing the system to perform the method.
[Problem] To provide an elongate material thickness measuring method and thickness measuring system for measuring a flow-direction component and a width-direction component of a paper thickness separately without the need for a conventional basis weight sensor employing radiation, wherein the thickness measuring method and thickness measuring system employ a non-scanning, non-filtering method, can be applied even to small papermaking machines, and have a high economic effect. [Solution] In this elongate sheet material thickness measuring method the thickness of an elongate sheet material W that is being rewound onto a reel spool 16 while being pressed against a reel drum 12 is measured. The thickness measuring method includes measuring in a non-contact manner an amount of increase in the roll diameter of a rewind roll R formed by the elongate sheet material W, measuring the number of revolutions of the reel spool 16, and obtaining the thickness of the elongate sheet material by means of a calculation employing the measured amount of increase in the roll diameter and the number of revolutions.
