WIRE OR FELT FORMING SECTION WITH BREAST ROLLER SUPPORTED BY HYDROSTATIC BEARING ABSTRACT OF THE DISCLOSURE A wire or felt forming section of a paper- making machine has breast rollers for guiding a respective one of two forming wires. The two rollers are disposed with a pulp gap formed between the two rollers and the wires are disposed just downstream of a pulp suspension ejecting nozzle of a headbox. Each roller is supported against the respective taut forming wire by a hydrostatic bearing. The hydrostatic bearing has two circumferentially separated resiliency chambers provided in a combined region of resiliency disposed over an arc of the circumference of the roller. A sealing strip after the region of resiliency prevents fluid from contacting the wire.
