Abstract: A tool for manufacturing a molded pulp wall covering is disclosed. The tool includes a flat tool base, a flat screen attached to the tool base, and a patterned grid that is removably attached to the tool base in a position over the flat screen. The shape of the removable attached patterned grid is used to shape the molded pulp wall panel produced by the tool. Different removable patterned grids may be used on the same flat tool base to produce wall panels with different shapes and patterns.

Abstract: Methods and apparatus for manufacturing a molded fiber part include: immersing a wire mesh mold in a slurry bath comprising water and fiber particles; drawing a vacuum across the wire mesh mold to cause fiber particles to accumulate at the wire mesh mold surface yielding a molded fiber part; transferring the molded part from the slurry bath to a die press assembly; and drying and die cutting the molded part in the die press assembly.

Abstract: A cam actuated system for precisely timing and quickly operating a locking and unlocking mechanism for a quick change press, said locking and unlocking system being made of at least four locking levers, with at least two of said levers located at each side of the press, and the cam actuated mechanism including a series of at least two cam rollers which roll along the first series of at least two cam tracks for locking said press, and along a second series of at least two cam tracks, each of the series of cam tracks being fixedly mounted at a predetermined location in the travel path of the press.

Abstract: In a precision moulding or finishing machine operating in continuous motion to form fully finished products from materials such as wood pulp, an improved system for transferring a preform into a transfer mould and thence into precision mating with a finishing mould in a pressing operation suitable for manufacturing products such as bowls, cups, pots and boxes, the preform remaining in one pair of moulds throughout the pressing operation. Transfer mould assemblies are transferred sequentially from one transporting carrier to another for fully rotatable mounting on releasable mounts guided precisely through a preferred endless travel path and orientation program. The concept of a releasably mounted and freely transferable transfer mould assembly provides for the addition of such functions as printing and labelling in the same continous production line.

Abstract: A molded pulp egg carton of the type having a pocketed bottom with a closeable cover integrally hinged to it wherein the cover has compact thickness, rigid firmness and densified hardness qualities obtained by being simultaneously dried and finish-formed between mating heated pressing molds, and the bottom has egg cushioning ribbons which have non-compacted consistency, resilient softness and an irregular fibrous feel and appearance obtained by being dried in a free space, defined by slots in a drying and pressing mold, without finish-forming pressure.
