摘要：The invention concerns a gap-roll former in a paper machine, comprising a headbox (30, 35, 36), which feeds a stock suspension jet (J) into the forming gap (G) defined by the forming wires (10, 20). Of the forming wires (10, 20), one wire is a covering wire (10) guided by its guide rolls (18), and the other wire is a carrying wire (20) guided by its guide rolls (21, 28), along with which carrying wire the paper web (W) follows after the twin-wire zone defined by said forming wires (10, 20). The twin-wire zone starts directly after the forming gap on a curve ctor (a) of the first forming roll (11). On the curve ctor (a) of the twin-wire zone on the first forming roll (11) there are at least two successive suction/pressure zones (11a, 11b), by who means a pressure effect that varies in the direction of progress of the paper web (10) can be applied through the perforated mantle (12a) of the first forming roll (11) to the paper web (W) that is being formed, so that the dewatering process on said curve ctor (a) can be controlled.个性网名男
