Abstract
A dewatering device has a dewatering box and a plurality of dewatering strips. A contour of at least one dewatering strip changes over its length. There is also described a machine for the production of a fibrous web, such as a paper, cardboard or tissue web, with a dewatering device of this kind, and to the use of the latter in a machine of this kind.
Claims12
A dewatering device, comprising:
- a dewatering box forming or delimiting a receiving plane;
- a multiplicity of dewatering strips disposed on said receiving plane;
- at least one of said dewatering strips having a longitudinal axis, an underside facing said receiving plane, and an upper side opposite said underside;
- said at least one dewatering strip being formed, in each case viewed in a section perpendicular to the longitudinal axis of said dewatering strip, with a vertical distance between said upper side of said dewatering strip and said receiving plane of said dewatering box continuously or discontinuously varying, or being variable, along the longitudinal axis of said dewatering strip;
- and
- said dewatering strip is divided along the longitudinal axis into a multiplicity of segments.
