  • Patent number: 10967545
    Abstract: A profiling calender includes an intermediate roll, a lower roll, and a pair of intermediate lugs. The intermediate and lower rolls are separated by a distance defining a height of a second profiling nip. The intermediate lugs are situated at ends of the intermediate and lower rolls and include two quarter-circle bearing surfaces that meet at the second profiling nip. Each end of the intermediate roll or each end of the lower roll is equipped with a collar fastened to the roll and positioned between the roll and a quarter-circle bearing surface of a corresponding intermediate lug. The collar enables a radius of the roll to be increased by a height equal to the separation distance in order to improve an appearance of edges of a profiled element produced by the calender.

    Abstract: A method for fibre placement with the aid of a roller is provided. The roller is able to pivot about a rotation axis and to lay a plurality of first pre-impregnated fibres on second pre-impregnated fibres of a laying surface by rolling over said laying surface. The first fibres being distributed along a lower generatrix of the roller and being in contact with an outer surface of said roller over a contact arc. The method includes cooling the first pre-impregnated fibres in contact with the roller so as to enable them to slide on the outer surface of the roller and heating the second pre-impregnated fibres of the laying surface that are located at the front of the roller so as to promote the adhesion of the first fibres to the second fibres of the laying surface.

  • Publication number: 20130115412
    Abstract: A fiber reinforced composite laminate with fibers generally oriented along two major axes and having a polyurethane resin matrix suitable for reinforcing wood based substrates such as trailer/container flooring, glulams, plywood, particle boards, laminated veneer lumber, and oriented strand board, is provided. The laminate is produced by pulling the fibers through a resin injection box, where a polyurethane resin is injected into the box to wet the fibers. The polyurethane resin wetted fiber layer is then covered with a release media on the top and bottom sides of the layer. The sandwich of fiber, resin and release media is fed to a double belt press capable of applying pressure and heat to consolidate and cure the laminate. The laminate thus made can be thinner than 0.080 inch and provides excellent flatness compared to pultruded thin laminates.

    Abstract: Two resin films each provided with an orally administrable edible agent layer are joined so that administrable agent layers face each other, drawn into a nip between a pair of press rolls, pressurized at back surfaces to bond the administrable agent layers together, and conveyed in a direction substantially conforming to a tangential direction at a pressurization zone of the press rolls. A delamination roll disposed in the conveying direction is used to draw only one of the two resin films sandwiching the bonded plural administrable agent layers in a direction different from the conveying direction, while continuously conveying the other resin film retaining the plural administrable agent layers in the conveying direction. This allows only one of the joined two resin films to be delaminated. The obtained pressure bonded product, that is, an orally administrable edible agent of laminate film form can be punched out into predetermined shapes.

    Abstract: A spunbond web formation apparatus includes a spinneret (1) of a spin pack (2) that extrudes an array of fibers (5) that are drawn into an aspirator (6). The attenuated fibers (8) discharged from aspirator (6) are deflected sideways by a Coanda device (7) that entrains the exiting air stream along with the fibers. The fibers are deposited on a vertically moving belt (9) and subsequently bonded by calender rolls (20, 21) to form a non-woven spunbond web. The spinning distance L is adjusted by vertically moving the aspirator (6), while the laydown distance M is adjusted by horizontally moving the belt (9) or aspirator (6) or by adjusting the size of the Coanda device (7). Deflection of the fibers exiting the aspirator permits the spinning distance L to be adjusted independently of the laydown distance M, without having to move the spin beam or adjust the height of the web-forming belt.
