  • Patent number: 5439215
    Abstract: An automated machine and process for the production of pultruded hockey sticks and similar linear products. The machine comprises a rigid elongated frame and a creel bank supplying rovings from individual spools. An elongated, rigid, hollow mandrel extends substantially along the entire length of the machine supported by the frame. A veil guide directs and wraps a veil around the mandrel at the front of the machine. The machine comprises serial segments, each having a pattern card, a gathering bracket and a spiral winding station. Each segment directs rovings onto the mandrel in a longitudinal layer circumscribed by a radial layer comprising separate spaced apart, continuous rovings forming concentric helixes. The winding stations are synchronized and counter-rotate. A third pattern card converges a third longitudinal layer of rovings toward the mandrel. A resin injection die penetrated by the manifold gathers the rovings from the third card and saturates the uncompleted product with resin.
