INVENTORS: ALFRED BUBIK and SIEGFRIED REUTTER INVENTION: DOUBLE FILTER PAPERMAKING MACHINE ABSTRACT OF THE DISCLOSURE A double filter papermaking machine comprising two filters guided over a dewatering cylinder. A first one of the filters contains a linear section or path located in front of the cylinder. A domed dewatering or slide shoe, shorter than such linear section, is arranged ahead of the cylinder. The second filter is equipped with an adjustable guide roll, by means of which it is possible to regulate the contact location of the second filter at the first filter, and specifically, between a location disposed at the starting region of the shoe and a location arranged after the shoe at the dewatering cylinder. A regulation device or regulator can be provided which contains a feeler for sensing the pos- ition of the water line at the dewatering cylinder. As a function of signals transmitted by the feeler the regulator adjusts the guide roll in a manner such that with a displace- ment of the water line from a reference position opposite the direction of movement of the filters the contact location is adjusted in the direction of movement of the filters and vice versa.
