ABSTRACT:
The web forming, guiding and/or transferring cylinder in the wire section of a papermaking machine has a deformable foraminous shell which is made of filamentary material and the end portions of which are clamped to rigid rotary ring-shaped end walls. The cylinder surrounds a rigid stationary back support which engages the internal surface of the shell opposite that portion of the external surface of the shell which contacts the web. The back support has grooves and/or ports which convey expelled liquid from the web into a suction chamber for admission into the saveall of the papermaking machine. One of the end walls is movable axially to change the axial tensional stress upon the shell. The back support has a convex external surface whose center of curvature may but need not be located on the axis of the cylinder.
