Abstract
The auxiliary roll of the separating system is located downstream of the main roll and is spaced from the main roll at a distance less than 0.25 times the diameter of the auxiliary roll and greater than the combined thickness of the two wires and paper web therebetween, e.g. a distance of 10 millimeters. A separating wall is located between the main roll and main wire on the upstream side to block the entry of air between the main wire and main roll. The spacing of the two rolls ensures a positive separation of the paper web on the main wire.
