Method for stabilization of paper-, cardboard- or other fibrous web in press section of fibrous web-manufacturing machine, involves drying fibrous web in press section in press nip, where press nip is made of two opposite press rolls

摘要

#CMT# #/CMT# The method involves drying a fibrous web (3) in the press section (1) in a press nip (2), where the press nip is made of two opposite press rolls, which are partially embraced by peripheral press felt straps i.e. an upper felt (6) and a lower felt (7). The lower felt is moisturized from its lower side (7a) after passing the press nip and even before the upper felt is separated from the lower felt at a felt separation point (FT), and the web that is separated from the upper felt continues to run onto the lower felt. #CMT# : #/CMT# An independent claim is included for a device for executing the method. #CMT#USE : #/CMT# Method for stabilization of paper-, cardboard- or other fibrous web in a press section of a fibrous web-manufacturing machine. #CMT#ADVANTAGE : #/CMT# The press felt straps i.e. an upper felt and a lower felt transport the fibrous web in a machine running direction, where the lower felt is moisturized from its lower side after passing the press nip and even before the upper felt is separated from the lower felt at a felt separation point, and the web that is separated from the upper felt continues to run onto the lower felt, and hence ensures high run-time efficiency of fibrous web-manufacturing machine with stable running of the fibrous web. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic cross sectional view of a press section of a fibrous web-manufacturing machine. 1 : Press section 2 : Press nip 3 : Fibrous web 6 : Upper felt 7 : Lower felt 7a : Lower felt lower side FT : Felt separation point.
