  • Patent number: 8906178
    Abstract: An optical fiber is permanently routed easily, quickly, and unobtrusively at a customer premises using an inventive hand tool, without staples or other fasteners. The fiber has an adhesive outer coating that is activated as the fiber is applied by the tool on an exposed surface such as a wall, ceiling, molding, groove, or corner at the premises. When the activated coating hardens, the fiber is bonded to the surface on which it was applied, and the hardened coating also provides physical protection for the fiber. In the disclosed embodiment, the coated fiber is supplied on a spool that mounts on the tool, and the coating is activated by guiding the fiber as it unwinds from the spool through a chamber containing an activating substance. The fiber with the activated coating is then guided to an applicator wheel on the tool which applies the fiber to the surface.

  • Patent number: 8127818
    Abstract: A method of jointing a cord fabric when the cord fabric for topping is alternately drawn from two supply positions for continuous supply. During drawing to supply of the cord fabric on one side, a start end portion of the cord fabric on other side is locked to hold by a locking pin of a jointing holder, and is set to a jointing mounting portion in a state where an unvulcanized jointing rubber member is pasted thereto. When a final end of the cord fabric on the one side comes closer, a finish end portion thereof is pasted to the start end portion of the cord fabric held by the holder by interposing the rubber member therebetween. The finish end portion and the start end portion are squeezed for joint from upper and lower sides by press members, thereafter, the holder is removed, and the cord fabric on the other side is drawn to supply continuously to the cord fabric on the one side.

  • Patent number: 8123515
    Abstract: This invention provides single-step pultrusion processes for producing fiber reinforced polymer (FRP) articles that may have variable cross sections and/or non-linear shapes. This unique capability results from the use of two sets of dies to form the article. The first is a set of moving dies connected together to form mating continuous loops of moving die links to: a) draw the FRP material into the apparatus; b) shape the cross section of the FRP material; c) cut the FRP material to the appropriate length; and d) hold the uncut FRP material in position for the next production cycle. The second set of dies forms a guide path mounted on opposing conveyers. The guide path includes heated die segments to define a curing section that may be non-linear. Cycling the moving die links through the curing section and/or cycling the conveyers provides a straightforward method for automated production of finished pultruded articles with unique shapes.

  • Patent number: 8066922
    Abstract: In the production of elongate plastic profiles (10), which usually takes place by the pultrusion process, the cured plastic profile (10) emerging from a die (14) is pulled through the stationary die (14) by a take-off device. This process only makes it possible to produce straight plastic profiles (10). The invention envisages producing curved plastic profiles (10) by using a die (14) corresponding to the curvature of the plastic profile (10). For moving the cured part of the plastic profile (10) out of the die (14), it is provided that the die (14) is moved back step by step in relation to the stationary plastic profile (10) counter to the direction of production (19). In order that the plastic profile (10) remains stationary in relation to the die (14) as this takes place, it is securely held outside the die (14) by a holding means (20) during the moving back of the die (14).

    Abstract: A plurality of unidirectional sheets (30a, 30b, 30c) are superposed in different directions and they are bonded together. At least one of the unidirectional sheets is made by spreading a tow so as to obtain uniform thickness, width not less than 5 cm, and a weight of no more than 300 g/m2, cohesion being imparted to the sheet so as to enable it to be handled prior to being superposed with other sheets. Advantageously, the unidirectional sheets are made of carbon fibers and are obtained by spreading out large tows.

  • Patent number: 7971616
    Abstract: An apparatus for applying weft yarns in a cross direction to warp yarns having an adhesive scrim thereon includes the warp yarns on a beam which are fed downstream of the apparatus by first laying the warp yarns onto a transfer belt to reduce the tension in the yarns. The warp yarns are fed upstream from a spool along a rotating tube on which they are mounted and pass through a tensioning apparatus to unify the tension in the various yarns running along the tube. The uniformly tensioned weft yarns pass through individual nozzles around the circumference of the rotating tube where the yarns are deposited onto the adhesive scrim. After the weft yarns are deposited on the warp yarns, the transfer belt moves the fabric having warp and weft yarns across a cooling section of a mandrel where the adhesive is set.

  • Patent number: 7832442
    Abstract: A fiber lay-up apparatus and method includes one or more fiber sources from at least one fiber supply wherein a fiber may be fed under tension to provide a pre-stress to the fiber. The fiber lay-up apparatus may include a resin impregnator for impregnating a fiber with a resin. The fiber may be impregnated under pressure to reduce friction, to provide a motive force to move the fiber through the impregnator, or to enhance control over impregnation. The fiber may be shaped by a fiber shaping unit including one or more active or passive shaping members that provide enhanced control over the shape and placement of the fiber as the fiber leaves the fiber lay-up apparatus. A cutting element for cutting a fiber as it is being layed-up may be positioned proximal to the one or more shaping members, and may enable the fiber lay-up apparatus to end the lay-up of one fiber (or set of fibers) and begin the lay-up of a new fiber (or set of fibers) without delay.
