  • Patent number: 8689685
    Abstract: In some embodiments, a dough pressing system includes a cover coupled to a pressing platen, wherein the cover can reduce the wear caused to the pressing platen by the heat and pressure used to process one or more products. The cover optionally can be configured to be removably attached to the pressing platen with vacuum pressure. In some implementations, one or more spacers are placed between the cover and the pressing platen. The thickness of the spacers can adjust the thickness and diameter of products processed by the pressing platen. For example, to increase uniformity among products pressed together in a press cycle, the spacers can have different thicknesses that correspond with the location of the spacer in the pattern of dough balls.

  • Patent number: 8387526
    Abstract: The present invention provides a precision press device and a press load control method thereof for downsizing a vacuum chamber in press work in the vacuum chamber, shortening a time required to reach a vacuum and further performing high accuracy pressure control. To downsize a chamber 16, a pressure sensor is set up outside the chamber 16 and a cylinder chamber 17 is formed to allow a tubular plunger 7 to slide up and down using the tubular shape of the chamber 16. A negative pressure 22 in the chamber 16 attracts the pressurized section 2 and the pressurizing section 1 to each other, but by injecting an equivalent pressure 19 of a fluid into the cylinder chamber 17, pushing out the tubular plunger 7, the attractive forces are canceled out. It is possible to control the load on the substrate or the like transferred by the press stage with high accuracy.

  • Patent number: 6972072
    Abstract: A device embodying the invention comprises a pair of members presenting a lower base surface and a member presenting an upper parallel surface when in an operative position. A platen pad material, which converts microwave energy to heat, is provided on one of the surfaces. When in an operative position the two platens provide uniform pressure over the surfaces of a laminating pouch carrying a document. The device is placed in a domestic microwave oven and the oven is operated for a period of time dependent on the rated power of the oven, the size of the document and the energy conversion capability of the platen pad. The platen pad converts the microwave energy to heat energy while applying uniform pressure over the surfaces of the pouch. This produces liquefaction of the adhesive which bonds the film to the document. The device is then removed from the microwave oven, permitted to cool, the lamination removed, and trimmed as may be necessary.

  • Patent number: 5824246
    Abstract: A method of forming a thermoactive binder composite product is performed by injecting a hot dry gas to activate the thermoactive binder. In the preferred embodiment, the hot dry gas is air. The method is particularly beneficial as applied to forming thermoplastic composite products and particularly thermoplastic/cellulose composites. Also part of the present invention is a two stage pressing process in which hot gas is injected during the first stage and the press charge is precompressed. The press charge is then placed in a second consolidation press where the hot gas is no longer injected and it is consolidated and cooled. Machinery for practicing the method includes a platen with a platen press which includes upper and lower platens with a plurality of hot air injection jets disposed on the surface of each platen. The platens are spaced apart and surrounded on the sides by an air-permeable containment shell structure to form a compression chamber to hold the base material to be pressed.
