ABSTRACT:
A paper machine has a forming wire loop which transports a web to a detachment transfer roll situated inside said wire loop at a detaching location where the web is to be detached from the wire and transported to a press section. A relatively dry felt engages the web on a sector of the detachment transfer roll at the detaching location and receives the web from the wire and continues to transport the web, while it adheres to the felt, to the press section. The detachment of the web from the wire on the detachment transfer roll is facilitated by the centrifugal force acting on the web which results from the substantial change of direction undergone by the web on the detachment transfer roll. In one embodiment, the press felt is directed to cover the web on a sector of the detachment roll by a press suction roll located on substantially the same level as the detachment transfer roll, the press roll having a suction sector which facilitates transfer of the web from the wire to the felt.
