Double wire forming device for fibrous web producing machine, has guide roll that is designed as press roll such that dehydrating pressure is generated between two wire portions by applied tension

摘要

#CMT# #/CMT# The device has wire portions (4,5) that are fed over peripheral regions (7,9) of deflecting elements (6,8). The wedge shaped gap (10) is formed between wire portions to receive fibrous material suspension (3) from head box (11). The wire portions are fed into twin-wire section (12) and guided over circumferential region (16) of guide roller (15). The two wire portions are separated by separation roller (17). The guide roll is designed as press roll such that the dehydrating pressure is generated between two wire portions by the applied tension. #CMT#USE : #/CMT# Double wire forming device for fibrous web producing machine used in producing paper, cardboard and packaging structure (all claimed). #CMT#ADVANTAGE : #/CMT# The guide roll is designed as press roll such that the dehydrating pressure is generated between two wire portions by the applied tension. Hence the dry contents in the fibrous web are increased at reduced energy consumption. The operating cost of the fibrous web producing machine can be reduced. The unwanted formation of fog in the region of double wire forming device can be reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the double wire forming device for fibrous web producing machine. 3 : Fibrous material suspension 4,5 : Wire portions 6,8 : Deflecting elements 7,9 : Peripheral regions 10 : Wedge shaped gap 11 : Head box 12 : Twin-wire section 15 : Guide roller 16 : Circumferential region 17 : Separation roller.
