  • Publication number: 20080099956
    Abstract: A mold for manufacturing stone products. The stone products have a major face, the major face has a texture that simulates the appearance of natural stone or brick, a back face opposed to the major face, a top face, a bottom face and a plurality of side faces, the stone product configured for installation with the major face in a vertical orientation. The mold comprises a flexible layer having a plurality of mold cavities. The mold cavities have a major wall configured to form the major face. The major wall have a texture configured for imprinting the desired texture on the major face, a back wall opposed to the major wall and configured to form the back face, a bottom wall configured to form the bottom face, and a plurality of side walls configured to form the side faces. The mold cavities are oriented such that the major wall is substantially vertical.

  • Publication number: 20080001323
    Abstract: An apparatus for manufacturing simulated stone products. The apparatus comprises a mold having one or more mold cavities. The mold cavities have a first section and a second section. The first and second sections have a longitudinal axis. The longitudinal axis of the first section intersects with the longitudinal axis of the second section to form a cavity angle. The first and second sections have top openings. The first and second sections are positioned such that castable material introduced into the top opening of the first section flows by gravity into the second section. At least one cover member is removably connected to the top opening of the second section of the mold cavity. The at least one cover member is configured to contain the castable material within the second section of the mold cavity as the castable material flows into the second section of the mold cavity. The at least one cover member is removable to allow the simulated stone product to be removed from the mold cavity after hardening.

  • Publication number: 20070148429
    Abstract: Disclosed are a series of composite polymer composite structures formed by the coextrusion of at least two distinct polymeric components. A first polymeric component includes a structural composition and a second polymeric component includes a coating composition. The primary structural frame formed from the structural composition includes at least one longitudinal recess. These recesses may be filled with a third polymeric composition that may include wood byproducts and/or a blowing agent. The first polymeric component may include reinforcing fibers at least partially coated with a size composition that includes a film forming agent, a lubricant, one or more additives, and first and second coupling agents. The additives may be chosen to achieve selective or desired properties in the end product.

  • Publication number: 20070141316
    Abstract: Disclosed are a series of composite polymer composite structures formed by the coextrusion of at least two distinct polymeric compositions including a structural composition and a coating composition whereby the primary structural frame formed from the structural composition includes at least one, and typically a plurality, of longitudinal recesses or cavities. These recesses or cavities may, in turn, be filled with a third distinct polymeric composition that may include wood byproducts and/or a foaming or blowing agent.

  • Publication number: 20070059506
    Abstract: Dried bundles of chopped glass fibers that may be used in mat forming applications is provided. The chopped glass fiber bundles are formed of individual glass fibers positioned in a substantial parallel orientation. The dried chopped glass fiber bundles may be prepared by applying a size composition to attenuated glass fibers, splitting the fibers to obtain a desired bundle tex, chopping the wet glass bundles to a discrete length, and drying the wet glass bundles in a dielectric oven, a Cratec® oven, or a rotating tray oven. Alternatively, the dried chopped glass bundles may be prepared by sizing attenuated glass fibers, passing the sized fibers through a heat transfer chamber where air heated by a bushing is drawn into the heat transfer chamber to dry the glass fiber bundles, splitting the dried, sized glass fiber bundles to obtain a desired bundle tex, and chopping the dried bundles of glass fibers.
