Pressenanordnung

摘要

Disclosed is a pressing device (10) of a paper and/or paperboard machine intended for the treatment of a fibrous web (12) which is formed on a band screen and passes around an appropriate open roller (16) having recesses intended to receive the water squeezed out the fibrous web. Said open roller forms with a counterface a first nip (18) which is extended, in the direction of movement of the L band, by a pressing shoe unit (20). A papermaker's felt (22, 24) passes both on the open roller (16) and said pressing shoe unit (20).
