Abstract (en)
[origin: EP0565112A2] The invention relates to a method, which is simple to execute, for monitoring the operation of mechanical paper shredders. The current coasting behaviour of the blade rollers is determined and compared with the coasting behaviour of correctly operating blade rollers. Deviations in the coasting behaviour indicate impairment of the operation of the blade rollers currently in use. Depending on the degree of deviation, measures are initiated which eliminate the operational impairment. <IMAGE>
