ABSTRACT:
A dewatering apparatus contains a longitudinal wire and an additional wire which is guided, conjointly with the longitudinal wire, along a section of such longitudinal wire over a domed or arched surface. This domed or arched surface is formed, for instance, by the jacket or outer surface of a dewatering cylinder arranged within the wire loop of the longitudinal wire. The longitudinal wire is provided with a headbox and extends forwardly and after the dewatering apparatus essentially in a wire plane, above which upwardly rises the domed surface. Both of the wires are guided out of the wire plane over a dewatering shoe arranged within the wire loop of the additional wire towards the domed surface and from such--if desired over a deflection roll arranged beneath the wire plane--again towards the wire plane, where both wires separate from one another. Due to this arrangement there is realized a guiding of both wires which improves the dewatering action and is extensively independent of the elevational position of the wire plane, and at the same time affords a constructional simplification of the papermaking machine.
