    Abstract: A method and apparatus for use in the manufacture of improved molded pulp products are disclosed wherein foraminous molds disposed over openings in a liquid impervious belt are moved beneath the surface of a flowing furnish and suction is applied to draw liquid through the molds and deposit a layer of pulp on each mold. Thereafter, the pulp deposit on each mold is simultaneously subjected to a generally uniform pressing with a second belt and suction which forms a smooth exposed surface on the pulp deposit and removes a portion of the liquid therein.

    Abstract: An expandable chuck for rotatably supporting a longitudinal roll, such as a tissue supply roll for a folding machine, having a hollow cylindrical core. Pneumatically inflatable tube members are mounted on spaced wheel members, which are in turn mounted on a cylindrical sleeve rotatably mounted on a support shaft. The tube members are pneumatically interconnected and the chuck is fully controllable from either end for insertion in or removal from the core of a roll by valve and vent means adjacent each end of the chuck.
