ABSTRACT:
A method for determining the quality of the formation of a reel or roll of a paper or board web and controlling the reel or roll formation or subsequent processing of the reel or roll based on the determined quality of the formation of the reel or roll. An oscillation signal produced by impulses formed in a web reel or roll during reeling or winding and arising from relative movements of web layers and/or from damaging of the web is measured and optionally stored. The measured signal is stored in electrical form as a function of time, reel/roll diameter, or the length of the web. The stored values are used in the control of the formation of reel or roll or in subsequent unwinding, reeling or winding of the reel or roll.
