Measuring Device and Method for Measuring the Arching of an Elongate Body

A measuring device (10) for measuring the arching (A) of an elongate body (12), characterized in that the measuring device (10) comprises an elongate beam (24) provided with an elongate anvil member (14) against which one long side of the elongate body (12) is intended to be placed, a measure-collection member (16) movable along the line of the longitudinal axis of the elongate body (12) via a driving unit included in the measuring device (10), which measure-collection member (16) is calibrated before measuring and is connected to a processor unit (18) for the processing of measured values, the measuring device (10) furthermore comprising a force-transmission member (20) for applying a predetermined force (F) directed toward the beam (24), where F≧0 N, to the elongate body (12) near the point of balance (C) of the elongate body (12), the applied force (F) being registered by means of a force-measuring member mounted on the force-transmission member (20), the measure-collection member (16), in abutment against and movement along the line of the longitudinal axis of the elongate body (12), continuously measuring a length (y) and a height (x) between the elongate body (12) and the measuring device (10), where y refers to the length between the points of contact of the elongate body (12) with the measuring device (10), and delivering a digital signal to the processor unit (18), which calculates the arching (A).
