ABSTRACT:
Apparatus for moving a submerged web through a liquid, comprising a cylindrical tube with ends adapted to prevent fluid flow out of said ends and/or with a peripheral area containing a plurality of uniformly sized and spaced apertures. A liquid pump, e.g. a venturi, supplies a flow of liquid into the tube allowing a moving web to be carried on a liquid bearing over a part of the aperture-containing peripheral area. The tube can be rotated, e.g. by a fluid jet, to assist in conveying a porous web being treated with the fluid providing web floatation off the tube.
