CA 2201668

A roll press for a cardboard or paper making machine that includes a suction press roll that lifts a cardboard or paper web from a screen and transfers the same to a press felt guided around the suction press roll and includes a pay-out press roll that forms a press gap with the suction press roll. The press felt and the cardboard or paper web may pass through the press gap, and, once through the press gap, the cardboard or paper web may be adhered to the pay-out press roll for paying out the cardboard or paper web to a subsequent part of the paper making machine. Both the suction press roll and the pay- out press roll are each associated with at least one additional press roll. The press rolls may be arranged to form three press gaps, at least one of which is an elongated press gap elongated in a travel direction of the cardboard or paper web. This arrangement provides a higher dewatering capacity in a compact roll press.
