Abstract
Apparatus and method for manufacturing a resin structure reinforced with long fibers. A continuous fiber bundle is impregnated with a resin melt while the fiber bundle is being drawn continuously. Thereafter, the continuous resin-impregnated fiber bundle is shaped so as to have a cross-section of the intended final product. The shaped resin-impregnated fiber bundle is then cut at a downstream location. Shaping of the resin-impregnated fiber bundle is accomplished by a plurality of rolls, each having grooves formed on the outer periphery thereof which receive the continuous resin-impregnated fiber bundle. The grooves and the rolls are arranged such that the rolls are placed, in an alternating manner, at upper and lower positions with respect to the fiber bundle which is being drawn and such that the grooves of the rolls on the elevation plane perpendicular to the running direction of the fiber bundle forms a shape of the cross-section of the intended final product.
