Abstract

"DISPOSITIVO DE PRENSAGEM". A presente invenção refere-se a um dispositivo de prensagem para desidratação de uma peça contínua de material fibroso, especialmente uma peça contínua de papel ou celulose, com dois cilindros de pressão (1, 2), que formam uma fenda de prensagem. Os cilindros de pressão (1, 2) estão montados em cavaletes de manca (4, 5; 11, 12), que estão ligados entre si respectivamente em um lado dos cilindros de pressão (1, 2). Os cavaletes de mancal (4, 5, 11, 12) dos cilindros de pressão (1, 2) estão ligados entre si através de um mancal giratório (15) diretamente e/ou através de talas de tração (16, 16<39>), sendo que as talas de tração (16, 16<39>) por sua vez estão ligadas com os cavaletes de mancal (4, 5, 11, 12) por meio de mancais giratórios (13, 14). A vantagem desse tipo de ligação dos cavaletes de mancal (4, 5; 11, 12) reside em que, quando de uma flexão dos cilindros de pressão (1, 2), forças adicionais não incidem sobre os pontos de apoio ou os pontos de ligação dos cavaletes de mancal (4, 5; 11, 12), pois a flexão dos cilindros de pressão (1, 2) é absorvida através das articulações giratórias (13, 14, 15)."PRESSING DEVICE". The present invention relates to a pressing device for dehydrating a continuous piece of fibrous material, especially a continuous piece of paper or cellulose, with two pressure rollers (1,2) forming a pressing slot. The pressure cylinders (1, 2) are mounted on housers (4, 5; 11, 12) which are connected to each other respectively on one side of the pressure cylinders (1, 2). The thrust bearings (4, 5, 11, 12) of the pressure cylinders (1, 2) are connected to each other by means of a rotating bearing (15) directly and / or through traction splints (16, 16 <39>). ), where the traction splints (16, 16 <39>) are in turn connected with the bearing stands (4, 5, 11, 12) by means of rotating bearings (13, 14). The advantage of this type of connection of the bearing stands (4, 5; 11, 12) is that, when bending the pressure cylinders (1, 2), additional forces do not fall on the bearing points or the bearing points. connection of the bearing stands (4, 5; 11, 12) as the bending of the pressure cylinders (1, 2) is absorbed through the swivel joints (13, 14, 15).
