Abstract

A cellulose dewatering machine for producing paper has a sieve dewatering device, a pressing device, a drying device and a subsequent transverse cutter, and the dewatering device has a round sieve cylinder unit.

1 . A cellulose dewatering machine for producing paper, comprising a sieve dewatering device, a pressing device, a drying device and a subsequent transverse cutter, said dewatering device having a round sieve cylinder unit.  
     
     
         2 . A cellulose dewatering machine as defined in  claim 1 , wherein said round sieve cylinder unit has four suction round sieves.  
     
     
         3 . A cellulose dewatering machine as defined in  claim 1 , wherein said round sieve cylinder unit has at least one turning press and a dandy roll press.  
     
     
         4 . A cellulose dewatering machine as defined in  claim 1 , wherein said pressing device has at least one smooth cylinder.  
     
     
         5 . A cellulose dewatering machine as defined in  claim 4;  and further comprising suction press rollers with which said at least one smooth cylinder cooperates.  
     
     
         6 . A cellulose dewatering machine as defined in  claim 4 , wherein said pressing device has a second smooth cylinder, said smooth cylinders being arranged so as to provide treatment of both surfaces of a cellulose web.  
     
     
         7 . A cellulose dewatering machine as defined in  claim 6 , wherein said smooth cylinder are provided with dryer hoods.  
     
     
         8 . A cellulose dewatering machine as defined in  claim 1 , wherein said drying device has at least one drying tower.  
     
     
         9 . A cellulose dewatering machine as defined in  claim 8 , wherein said at least one drying tower has vertical flow nozzles.  
     
     
         10 . A cellulose dewatering machine as defined in  claim 8 , wherein said drying device also has a swing tower for heating or cooling a cellulose web, and a cooling tower, which towers follow said at least one drying tower.  
     
     
         11 . A cellulose dewatering machine as defined in  claim 1 , wherein said drying device has a horizontally arranged drying passage for a cellulose web.  
     
     
         12 . A cellulose dewatering machine as defined in  claim 11 , wherein said drying passage has three portions including a first portion for drying with hot air, a second portion for heating or cooling, and a third portion for cooling the cellulose web.  
     
     
         13 . A cellulose dewatering machine as defined in  claim 11 , wherein said drying passage has an automatic web running edge control.  
     
     
         14 . A cellulose dewatering machine as defined in  claim 4;  and further comprising a dancer roller arranged between said smooth cylinder and said drying device.  
     
     
         15 . A cellulose dewatering machine as defined in  claim 1;  and further comprising measuring and indicating devices for a residual moisture and a temperature of a cellulose web before an entry to said transverse cutter.
