Method and device for transferring a paper web

摘要

Method and device for transferring a paper web to a transfer suction roll 13. The transfer suction roll 13 comprises a roll shell 16 and a perforation 17 through said shell and end flanges 18a, 18b, to which a tubular shaft 19 is connected. In the method, adjustment of the suction area of the transfer suction roll 13 is synchronised with the cutting movement L1' of a cutting nozzle 15a, which cuts the paper web in such a way that the suction effect of the transfer suction roll is directed solely towards the cut part C1 of the paper web, which is to be transferred to the transfer suction roll 13 and through this on to the felt 14 and onwards. <IMAGE>
