ABSTRACT:
Apparatus for continuously shaping a heated thermoplastic synthetic resin sheet into a desired configuration followed by any desired processing, wherein the synthetic resin sheet extruded from a forming die is drawn by suction onto a shaping surface of the apparatus main body which is provided therein with a heat transfer medium accommodating chamber to constantly maintain the shaping surface of the main body at an appropriate temperature by quickly heating the shaping surface to an appropriate temperature prior to commencement of operation of the shaping apparatus, and by cooling the shaping surface to prevent the same from temperature rise due to contact with the heated synthetic resin sheet after the shaping apparatus starts operation. The apparatus is further provided with a heat transfer medium feeding means to automatically feed the heat transfer medium at a desired temperature into the heat transfer medium accommodating chamber. According to the apparatus of the present invention the heated synthetic resin sheet can be shaped into a desired configuration followed by any desired processing by maintaining the shaping surface of the main body at an appropriate temperature.
