发明名称 VALS FOER FORMNINGSPARTIET I EN PAPPERSMASKIN ELLER LIKNANDE
摘要 The invention relates to a roll (8) for the forming section of a paper machine or the like, comprising a perforated shell (17) for removing water from a fibre suspension through holes (18) in the shell (17) into the roll (8) and being arranged to be mounted rotatably in the machine. A wire (3; 10) or the like within the forming section is arranged to be in contact with the shell (17) of the roll (8) over a part of its periphery. For improving the dewatering and the formation, the roll (8) comprises, at least substantially over the peripheral portion in contact with the wire (3; 10), bladelike means (21; 33) extending in the longitudinal direction of the roll (8). The blades are positioned within the shell (17) close to the inner surface thereof and mounted in such a manner that the shell (17) moves relative to the blades when the roll (8) rotates.
