Attorney's Docket No. 8033 CAN INVENTORS: RUDOLF M?NCH and ELMER WEISSHUHN INVENTION: MEASUREMENT APPARATUS FOR MEASURING THE TRANSVERSE PROFILE OF A PAPER WEB ABSTRACT OF THE DISCLOSURE A measuring bridge is stationarily located above a moving paper web and substantially transversely arranged relative to the direction of movement of the latter, the measuring bridge being provided with a measuring head which is reciprocatingly movable in substantially transverse direction with respect to the moving paper web at the measuring bridge for determining the measured values for evaluating the transverse profile or thickness of the moving paper web at the measuring locations, above which the measuring head is located at respective moments of time. The measurement apparatus comprises a process guiding system in which a traversing path scheduling program is inserted, according to which a traversing time or crossing time and/or a reversing time or waiting time of the measuring head are varied subsequent to each paper web traversing or crossing at the stationary measuring bridge. In this manner, the frequency of the measurements along the moving paper web is irregular, thus precluding misinterpretations of the transverse profile of the paper web and the generation of subsequent unsuitable regulating commands of a control computer.
