Apparatus, methods, and fabrics for dewatering a nascent paper web, carried in a web sandwich, in a dewatering section of a papermaking machine. Water is driven from the web by a combination of mechanical pressure and compressed air, both typically applied in a nip. The mechanical pressure and air pressure can be applied in the same nip, or in separate nips, where the mechanical pressure is applied upstream, in the papermaking machine, from the air pressure application. The mechanical pressure can be lower than pressures used in conventional press sections of known papermaking machines. Air pressure is that pressure which can be contained in a seal section between the web sandwich and the structure supplying the air. Fabrics supporting the nascent paper web through the air dewatering station have limited lateral air flow under compressed air conditions, whereby air flows generally perpendicularly through the web being dewatered.

A method for producing a fibrous material web, particularly for producing a tissue or hygienic paper web, in which a fibrous suspension is dewatered in a crescent former to obtain a fibrous material web, and dried on a Yankee. After the crescent former, the fibrous material web is guided along with the forming screen and felt over a suction roller downstream of the forming roller. A device for carrying out the method for producing a fibrous material web.

A paper pulp pressure apparatus includes a body casing having a pipe member and a leg member. The leg member extends diagonally from the pipe member. The pipe member includes an input end for receiving unfiltered fluid and an output end for outputting filtered fluid. The leg member includes a basket for receiving the unfiltered fluid from the input end. The basket includes a cavity which receives a rotor. The leg member includes a drain outlet which is in fluid communication with the cavity of the basket so as to receive contaminants from the unfiltered fluid unable to pass through a filtering media included in the basket.
