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. Within the injection die, the mandrel has small diameter passages extending from a central bore to grooves on the surface for conveying resin from the bore to the rovings. A second veil guide directs an outer veil onto the resin impregnated rovings. A heater penetrated by said manifold heats the resultant resin impregnated product. A curing die helps to maintain the outer shape imparted by the injection die and the heater while the product cures. Modified industrial pullers are used to pull the rovings about the mandrel at a predetermined linear speed to form the product.
