Abstract

It includes an extended press nip between a rotatable roll shell (10) and a shoe (11) having a concave surface (12) facing the nip with a piston (16) and cylinder (17) support for the shoe and a stationary shaft (26) extending through the roll shell (10) and a piston (32) and cylinder (33) support opposite the nip be­ tween the roll shell (10) and shaft (26) with the shoes (11, 29) being essentially the same area and providing opposed equal and opposite forces and the ends of the shafts being supported on a universal bearing (27, 28) so as to permit bending of the shaft (26) with the shell (10) being driven by a gear (38) on the shell and drive gears (39, 40) laterally of the nip and spaced diametrically opposite to each other.
