Abstract
An apparatus for the manufacture of sections of thermoplastic resin reinforced with continuous fibers. The apparatus includes coating rovings, having their fibers previously arranged in the form of a sheet by passage through a baffle zone having at least one transverse baffle, in a coating zone fed with a molten thermoplastic, then, to ensure impregnation of each of the fibers of the rovings, the coated rovings are passed into a forced impregnation zone having at least two baffles parallel to the baffle in the baffle zone prior to passing into the channel for shaping the final product.
