Abstract
A measuring device is releasably received within a winding core of a customer roll wound on a slitter-winder (). The measuring device () is releasably fastened within the winding core by fastening element(s) () securing the device to the winding core () for rotation during winding of the fiber web around the winding core to form the customer roll. Eccentricity of the customer roll as it is wound is determined from movement, speed and/or acceleration data received from at least two sensors of the measuring device and data is stored for use in unwinding the fiber web from the customer roll and serving as control information. Tension variations in unwinding can thus be anticipated and premeditative steps taken to ensure smooth running of the fiber web in unwinding in further processing.
