  • Method and apparatus for the in-line impregnation of fibers with a non-aqueous chemical treatment
    Patent number: 6027680
    Abstract: A method and apparatus is disclosed for the in-line pre-impregnation of glass or synthetic fibers with a non-aqueous chemical treatment. The apparatus includes a first applicator for applying a curable, non-aqueous chemical treatment agent and a second applicator for applying a curing agent for the chemical treatment agent. The fibers are passed over the first and second applicators which are arranged either in parallel or in series, and are then joined by a gathering device to initiate curing of the chemical treatment agent on the fibers. In an alternative embodiment, the apparatus includes a spray gun in which a mixture of the non-aqueous chemical treatment agent and curing agent are sprayed onto an applicator roll in contact with the fibers.

  • Method and apparatus for the in-line production and conversion of composite strand material into a composite product
    Patent number: 5914080
    Abstract: A method and apparatus is provided for the in-line production of composite strand material and the conversion of at least a portion of the strand material into a composite product. The apparatus (10) includes a combining station (48) where glass fibers (14) with a second polymeric material (66) are combined to form composite strand material (16), and at least one mold (54) for receiving a portion of the composite strand material and forming the portion into a composite product. The apparatus also includes transfer equipment for moving the composite strand material from the combining station to the mold, which may include a computer-controlled robotic arm (52). In another embodiment, the apparatus includes a collecting device (18) for accumulating the composite strand material (16) in looped form and equipment for delivering the accumulated portion from the collecting device to the mold (54).
