ABSTRACT:
In order to produce a reduction in the content of suspended matter in the surplus white water in a twin-wire machine with a curved forming zone, an outer saveall for collecting white water thrown outwardly from the curved forming zone is divided up into at least two separate saveall compartments arranged after each other in the direction of travel of the wires. The white water that is caught in the separate saveall compartments is removed as separate fractions for reuse.
