  • Patent number: 7789645
    Abstract: A structural cementitious panel, produced by a multi-layer process including providing a moving web; b. one of depositing a first layer of loose fibers upon the web and c. depositing a layer of settable slurry upon the web; d. depositing a second layer of loose fibers upon the slurry; e. embedding said second layer of fibers into the slurry; and f. repeating steps c. through e. until the desired number of layers of settable fiber-enhanced slurry in the panel is obtained. Also provided are an apparatus suitable for producing structural cementitious panels according to the present process, and a structural cementitious panel having multiple layers, each layer created by depositing a layer of settable slurry upon a moving web, depositing fibers upon the slurry and embedding the fibers into the slurry such that each layer is integrally formed with the adjacent layers.

  • Patent number: 7753669
    Abstract: A system for flexing a web is disclosed. The web passes over two co-rotating members, such as rollers or belts, which are separated by a small adjustable gap. The web travels around the first rotating member, is peeled off in the vicinity of the gap, bent back on itself in a small radius and reattached on the second co-rotating member. The location of the small radius is fixed with a closed loop control system sensing the radius location and controlling the relative velocity of the two members. Strain in the web is adjusted with the size of the small radius, which is controlled by the adjustable gap and radius location.

  • Patent number: 7677880
    Abstract: A system includes a high speed reciprocating mold plate patty-forming machine and a downstream patty presser. The high speed patty forming machine provides patties at a high production speed onto an output conveyor portion. The patty presser includes an upper conveyor having an upper endless belt. The upper conveyor is located above the output conveyor, wherein facing belt surfaces of the upper and lower endless belts define a path between the upper and lower conveyors. The upper conveyor has a tilted section such that a first clearance at an input to the path is equal to or greater than a thickness of the patties and a second clearance at an outlet of the inlet length is less than a thickness of the patties at the input of the path. A shuttle conveyor is arranged at the output of the path and delivers patties to an indexing packaging machine.

  • Patent number: 7611660
    Abstract: The present invention relates to an apparatus and method for cooling material during continuous vacuum forming. The apparatus includes one or more cooling regions positioned adjacent one or more vacuum regions. A rotatable support belt including perforations therein supports a flexible patterned belt. The flexible patterned belt includes apertures spaced along the length and width thereof. The one or more cooling regions provide a cooling fluid to be drawn through the apertures in the flexible patterned belt to form an area of cooling fluid on the flexible patterned belt which contacts a bottom surface of a hot material received on the flexible patterned belt in order to cool the bottom surface of the material and the flexible patterned belt. The vacuum regions are in fluid flow communication with the perforations of the support belt and the apertures of the flexible patterned belt for drawing the material onto the flexible patterned belt.

  • Publication number: 20090250838
    Abstract: Provided is a method for manufacturing a high-quality porous film. Here, while the porous film is being manufactured through forming micropores by stretching, a raw film is prevented from slipping on the surfaces of the respective rolls as much as possible even though the raw film includes oil or liquid paraffin as a solvent. The method is for manufacturing a porous film through forming micropores by successive biaxial stretching. A tensile force applied to the raw film F transferring from the longitudinal stretching machine (10) to the transverse stretching machine (50) is set not less than a stretching force necessary for the longitudinal stretching, and thus the raw film is prevented from slipping on a contact surface between the raw film and each roll of the longitudinal stretching machine (10).
