PURPOSE:To shorten cooling time and reduce line space by a method wherein the production device of the material concerned consists of impregnating die section, in which molten resin is kept under molten stage, and cooling die section, in which the molten resin is cooled down to its melting point, so as to cool and solidify the molten resin, which is infiltrated in longer fiber bundle at the impregnating die section, at the cooling die section. CONSTITUTION:Rovings 6 of aramid fiber are respectively introduced through the through holes 32 of an introductory fitting and passed through shaft section 31, impregnating path 20, take-off path 21, second take-off path 52 and cooling die section 5 and, immediately after leaving the cooling section, taken off with a take-off. Further, simultaneously molten nylons 6, 6 are charged into impregnating die section 2. The impregnating die section 2 is heated with heater 23, while the cooling die section 5 is cooled by feeding water having room temperature in cooling water path. Thus, the rovings 6 are impregnated with molten nylon 6, 6, taken off with a take-off and cut with a pelletizer. At this time, nylon 6, 6 infiltrated in the rovings 6 is already cooled down and solidified, surely taken off and, at the same time, easily can be cut off. |
