Abstract: A control system for measuring a gap in an apparatus for pressing a traveling paper web as the paper web travels through the gap accompanied by at least one belt or felt, the apparatus including a press apparatus and a support surface defining a gap therebetween. A frame is provided for moveably supporting the press apparatus. An actuator is operatively disposed between the frame and press apparatus for selectively moving the press apparatus toward and away from the support to control the gap size. A transducer is mounted in either the press apparatus or support for producing a signal indicative of the pressure on the paper web as the paper web, belt and felt pass through the gap beneath the transducer. A controller is operatively linked with the transducer for receiving the signal, determining the measure of the gap as a function of the pressure, and causing the actuator to selectively move the press apparatus to control the gap size.

Abstract: The front wall and support arrangement is shaped as a stiff support structure extending across the entire machine width above a slice chamber. The support structure is deformed due to its inherent weight and because of the pressures and temperatures prevailing in the slice chamber. To counteract these deformation effects the support structure is supported by a support carrier of about the same length as the support structure. To attain a substantially lower structural height, the support carrier is arranged relative to the support structure such that an intermediate space prevails between the lower wall of the support structure and the support carrier. This intermediate space accommodates force-generating support elements. Each of the force-generating support elements is provided for only a portion of the surface or area to be supported in the intermediate space. In a preferred embodiment the support structure is a box-like girder equipped with an upright positioned I-profile constituting the support carrier and arranged within the interior space of the box-like girder. Advantageously, the support elements are elastic tubes closed at both ends and extending substantially parallel to the longitudinal axis of the front wall, and the individual elastic tubes are each connected to at least one pressure source.
