ABSTRACT:
The invention is a process for the manufacture of sections of thermoplastic resin reinforced with continuous fibers and the equipment for carrying out the process. The process consists of coating rovings, having their fibers previously arranged in the form of a sheet, 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 prior to passing into the channel for shaping the final product.
