Rotary Or Swinging Carrier Patents (Class 162/391)
  • Patent number: 6793775
    Abstract: A plurality of glass deposition targets are rotated simultaneously and a first plasma torch, having a coil diameter larger than the sum of the target diameters, deposits glass simultaneously on the plurality. After the diameter of the targets reaches a threshold a second plasma torch is used. The diameter of the second plasma torch can provide for simultaneous deposition. In a further embodiment, after the target diameter reaches a second threshold a third plasma torch is used. In a further embodiment the spacing between the axes of rotation of the targets is widened as the target diameter increases. In a still further embodiment a single plasma torch includes movable concentric tubes within its coil to selectively operate as any of a plurality of different diameter plasma torches.

  • Patent number: 6716319
    Abstract: Apparatus for producing a molded pulp product from a fiber slurry comprising a dip tank containing a fiber slurry therein and having a liquid level. A platen is provided. A porous mold is carried by the platen. The platen and the mold carried thereby are lowered into the fiber slurry in a downward direction with the platen being disposed upwardly of the mold so that the mold is introduced through the liquid level into the fiber slurry. A vacuum is supplied to the platen and to the mold while the mold is disposed in the fiber slurry to cause fibers in the fiber slurry to collect onto the mold and form a wet molded pulp product. The platen and the mold with the wet molded product thereon are moved out of the fiber slurry through the liquid level to permit water to drain from the mold and the wet molded pulp product. The wet molded pulp product is then dried.

  • Publication number: 20030136537
    Abstract: The invention relates to an apparatus and method for producing articles (5) from moulded pulp material that are laminated with a plastic film (4). Thus an environmental friendly and water-resistant package for food products and for other moulded pulp products such as packages for industrial products is provided. The apparatus comprises a moulding line 1 and a laminating line (3). The moulding line (1) comprises a suction moulding station (20) with a pulp vat (25) and a number of suction moulds (22), a drying oven (28) and conveying means (26,28) for transporting the moulded pulp articles through the moulding line (1). The articles are transported in line by a conveyor 10 from the moulding line (1) to the laminating line (3), the laminating line (3) comprises a plastic film supply unit (47), a heating station (69) a laminating station (80) and conveying means (56) for conveying the articles (5) through the laminating line (3).

  • Patent number: 6517684
    Abstract: Method of manufacturing articles from an aqueous fibre suspension, by deposition of fibres on a suction mould (2), comprising the steps of: applying suction to the suction mould, supplying a fibre suspension to the mould by immersing the suction mould in a vat (5) containing the fibre suspension, raising the suction mould from the fibre suspension, flowing ambient air by said suction through an article formed by a layer of fibre material deposed on the suction mould, characterised by the steps of: providing a substantially hermetically sealed space over the article or articles on the suction mould, supplying a de-watering fluid to the sealed space, and flowing substantially exclusively the de-watering fluid through the article or articles.

  • Patent number: 6245199
    Abstract: A automatic pulp-forming mold-releasing machine comprising a lower mold disposed inside of a frame body, capable of reciprocatingly turning upside down and having protruding forming parts at top and bottom sides thereof which include air vents on the surface thereof capable of drawing and blowing air, and two synchronically reciprocatingly laterally shifting slide holders disposed at the top of the frame body and having upper mold lifting devices to drive the upper molds to move upwards and downwards, and air-drawing and air-blowing vent provided inside of the upper molds, and a liftable pulp container disposed under the lower mold of the frame body, characterized in that the pulp is absorbed to the forming parts at the bottom side of the lower mold; thereafter, it turns upside down to the top side, after dehydrated by the down-pressing of the upper mold, the formed pulp is absorbed upwards and lifted to be separate from the mold while the upper mold is laterally slid by the slide holder in position so that t

  • Patent number: 5174863
    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.

  • Patent number: 4448640
    Abstract: The invention concerns a process and device for molding and drying objects made of fibrous materials.The device comprises a cylinder 12, rotating about its longitudinal axis, having a row of porous molds 18 along the lengths of said cylinder's lateral faces, partially dipping into a vat 10 maintained with a constant level of fibrous product paste made of an appropriate liquid, a tubule 20 which connects the interior of the cylinder with a source of vacuum so as to create a partial vacuum therein, said cylinder 12 surrounded on its entire lateral surface free between paste vat 10 and removal device 22 by an arrangement of insulating walls 42 which define with cylinder 12 and vat 10 an enclosure 44 into which opens passageway 46 conveying hot air, said hot air being dwarfed from the extraction of air from a dryer.The present invention notably applies to the formation of egg boxes.

  • Patent number: 4220537
    Abstract: A drum type disc filter device for dehydrating paper pulp slurry. The drum and the disc filters are axial drain chambers and sector type filter members. Pressurized air is fed into the drain chambers sequentially when each drain chamber and corresponding filter members are at a predetermined angle of rotation of the drum. Paper guide plates are secured between the disc filters to guide separated paper pulp cakes safely into a chute without causing interference of lumping of the paper pulp cakes.

  • Patent number: 4162935
    Abstract: A coffin for a human being molded of papier-mache. The coffin is formed with ribs that provide strength to the structure and at the same time have a decorative effect. The improved method of forming the coffin includes drawing paper pulp onto the molds while the latter are inverted so that there is a heavy flow of pulp by gravity to the open end of the coffin to produce heavier flanges. When the mold is received from the pulp with the coffin molded onto it, an air impervious blanket is placed over the coffin when the vacuum is applied to suction the water from the papier-mache so that greater compression of the pulp is obtained to produce a stronger papier-mache structure and reduce the drying time.
