  • Patent number: 9701060
    Abstract: Extrusion-to-sheet production line and method comprise first and second rolls set to a predetermined gap through which a continuously-extruded sheet of molten plastic material passes to calender the sheet to a predetermined thickness. The sheet passes through a nip formed between the second roll and a continuous belt looped around a third roll and a fourth roll. The belt comprises an embossing pattern of optical element shapes that is an inverse pattern of optical element shapes to be embossed at a first major surface of the sheet. The sheet remains in contact with the second roll until the sheet passes through the nip, where the pattern of optical element shapes on the belt is embossed into the first major surfaces of the sheet. Downstream of the third roll is a cooling area through which the belt passes.

    Abstract: A coating die having a shut-off bar positioned to stop the flow of coating material within the flow channel of the die when the shut-off bar is in the closed position. In the closed position, the shut-off bar extends across the material flow channel, blocking flow of coating material therethrough. The shut-off bar moves essentially orthogonal to the direction of material flow. In some embodiments, the flow channel includes a shoulder against which the shut-off bar physically seals, the seal being essentially transverse or orthogonal to the direction of the material flow channel. Coating dies having a shut-off bar are particularly suited for patch coating applications.

  • Patent number: 8177541
    Abstract: Disclosed is a gypsum board forming device which provides improved slurry spread. The device includes a forming table with an arcuate or angled profile that promotes a uniform slurry spread. An arcuate or angled hinge plate can also be included to further promote the uniform distribution of slurry prior to an extrusion plate. As a result of the improved slurry spread, gypsum board with increased strength and durability can be created.

  • Publication number: 20120063811
    Abstract: A resin casting mold includes a mold member forming a cavity that includes first and second surfaces facing each other in a first direction. The mold member further includes an insert member which forms a part of a third surface and which is slidable in a second direction perpendicular to the first direction. At least one cross-sectional shape of the cavity satisfies h<A<H, where “A” is the length of the insert member in the first direction, “h” is a spacing in the first direction between a portion of the first surface closest to the insert member and a portion of the second surface closet to the insert member, and “H” is the length in the first direction on the third surface. The insert member is disposed to include a region having the spacing “h”.
