Abstract (en)
[origin: WO2021254732A1] The invention relates to a roller for producing a fibrous material web, in particular a paper web, comprising a main rotationally symmetrical main body which is rotatable about a longitudinal axis and has a lateral surface on which there are arranged at least two elastically deformable and/or deflectable annular lamellas which extend away from the lateral surface in the radial direction and which surround the main body in the circumferential direction, the lamellas being arranged at least in portions at an angle to a centre plane of the roller oriented perpendicularly to the longitudinal axis of the roller, thus forming an angle of inclincation.
