Abstract (en)
[origin: WO2009156314A1] The invention relates to a method for identifying the state of a belt, especially of a steel belt, originally having an at least substantially closed surface, of a machine for manufacturing and / or treating a fiber furnish web, particularly a paper or cardboard web and, in particular, for the purpose of identifying cracks in the belt. For this method, the belt, circulating in the production machine, is monitored online by means of the least one optoelectronic detector with at least one light emitter, acting upon the circulating belt with light, and with at least one light receiver, receiving the light affected by the circulating belt, for the condition of the belt or for cracks.
