  • Patent number: 6158142
    Abstract: A vise having vise members is provided with a vise face on each vise member. The vise faces are opposed and together define an initial vise volume having an open top for receiving loose, wet screenings. The vise faces form jaws moved relative to each other to squeeze the loose, wet screenings, which is a process of enclosing and applying force to the loose, wet screenings to compress the screenings and force the liquid out of or from the material of the screenings. The squeezing makes a loaf volume significantly smaller than the initial volume, and converts the loose wet screenings into a separate dry loaf. A platform has many separate stations. At one station (e.g., receiving & squeezing), a bottom of the trough is sieve-like for draining the liquid from the wet screenings. At another station (e.g., conveying), the bottom of the platform is closed to retain the separate dry loaf of screenings for conveying. At another station (e.g.

  • Patent number: 4431404
    Abstract: Apparatus is disclosed for heating a plurality of sheets of plastic material between adjacent ones of a plurality of vertically stacked and individually heated platens. The platens are vertically displaceable together and relative to one another, and any two vertically adjacent platens are vertically separable relative to a fixed horizontal pass line to facilitate removing a heated plastic sheet from between the platens and introducing a plastic sheet to be heated therebetween. Vertical separation is achieved by latching the upper one of two adjacent platens in a fixed holding position above the pass line and lowering the lower one of the two platens and any other platens of the stack therebeneath to position the upper surface of the lowered platen at the pass line. Sheet discharge and feed mechanisms are then operable respectively to remove a heated sheet from the lower platen and introduce a sheet to be heated onto the lower platen.

  • Patent number: 4192079
    Abstract: A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet.Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings.
