    Abstract: A series of flat articles are advanced along a path at regular intervals and are folded by continuously traveling fingers which engage an article intermediate its ends and fold the same. The fingers advance the articles to a station at which the folded articles are deposited as the fingers automatically withdraw from the folds. The folded articles may be abutted seriatim into a stack within an accumulator in the form of a conveyor traveling a speed considerably slower than the speed of the traveling fingers.

    Abstract: A multi-ply bias laid ribbon is formed by an apparatus and a method in which at least one web is spirally wound onto a flat, vertically disposed mandrel as the web discharges at a helix angle from a web guiding and folding bar means. The latter is carried in a circular path about the mandrel and shifted vertically at substantially the speed of travel of web receiving mandrel belts during application of the web onto the mandrel belts.

    Abstract: An apparatus for making molded pulp products is disclosed wherein foraminous molds disposed over openings in a liquid impervious belt are moved through a channel 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. A stationary boundary surface of the furnish channel has an arcuate configuration conforming to the catenary of the belt, and includes suction grooves oriented to subject the molds to continuous suction as the molds are moved along the boundary surface.

    Abstract: A MULTI-PLY RIBBON IS FORMED BY APPARATUS IN WHICH AT LEAST ONE WEB OF MATERIAL IS WOUND SPIRALLY ABOUT A MANDREL AND THEN STRIPPED AND FLATTENED. TO REDUCE INERTIA AND GYROSCOPIC FORCES ENCOUNTERED WHEN UNWINDING A WEB PARENT ROLL ABOUT ITS LONGITUDINAL AXIS WHILE IT IS SPINNING RELATIVE THE MANDREL ABOUT ANOTHER AXIS, THE PARENT ROLL IS MOUNTED IN A ROTATABLE CARIER AT ONE END OF THE MANDREL WITH THE RESPECTIVE AXES BEING SUBSTANTIALLY COPLANAR. THE MANDREL MAY BE SUSPENDED FROM THE CARRIER AND DRIVEN IN A DIRECTION REVERSE TO THAT OF THE CARRIER SO THAT THE MANDREL REMAINS STATIONARY RELATIVE TO NIP ROLLS. THE PREFERRED RIBBON IS FORMED OF BIAS LAID, SUPERIMPOSED PLIES OF CREPED TISSUE AND HAS THE SURFACES OF THE RIBBON TEXTURED BY SPACED DEPRESSIONS AT WHICH FIBERS IN ONE PLY ARE INTERLOCKED WITH FIBERS IN AN ADJACENT PLY.

    Abstract: A continuous cohesive multi-ply ribbon is made by forming a continuous spiral wound tube of creped tissue, flattening the tube and joining the plies of the flattened tube by embossing the plate together. After the spiral wound tube is formed, it is passed through a pressure nip formed by two rolls, thereby flattening the tube. Droplets of water are sprayed on one of the rolls. The water is carried to the pressure nip on the one roll and there transferred to the flattened tube as it enters the pressure nip. The moistened flattened tube is then passed through an embossing nip where the plies of the tube are pressed together at spaced locations with pressure sufficient to crush the fibers of the respective plies into one another, the water thus added to the creped tissue being sufficient for the crushing of the fibers to attach the plies together at said spaced locations with a glassine-type attachment.
