(57) 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 between 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.
