ABSTRACT:
In a web pick-up device and a method of using the pick-up device in the press section of a paper machine, the running web makes contact, in a press gap, with a smooth rotating surface from which the web runs off at a point of pickup (A). The rotating surface and a suction box form together, in the area of the pickup point (A), a gap through which runs a porous conveyer belt which receives the fibrous web. The suction box is pivotably mounted and has in the area of the point of pickup (A) a sliding surface across which slides the conveyer belt, and which during operation is arranged at an adjustable spacing from the smooth surface. The spacing is determined by a stop on which bears the suction box during operation, under the effect of a flexible lift device.
