Abstract
The invention relates to a method for monitoring the condition of a continuous element (44) moving in a fiber web or paper finishing machine, said monitoring being performed with a rotating machine element (41), which is equipped with a sensor assembly (24) that measures force or pressure and against which the continuous element moves. In the method, the machine element is made to rotate against the continuous element, a measurement signal (25) is generated between the machine element and the continuous element with the sensor assembly, and a cross-directional profile (21) of force or pressure generated between the machine element and the continuous element is formed from the measurement signal. Said moving continuous element is a fabric (32, 33) installed in a fabric run (22, 23) traveling via the machine element. In the method, the fabric is additionally installed in a fabric run, wherein it moves via said machine element equipped with a sensor assembly, a reference profile (35) is formed for the cross-directional profile after installing the fabric in the fabric run, the cross-directional profile formed from the measurement signal and representing force or pressure generated bet…
