Abstract

PURPOSE: To raise the performance of disk by manufacturing a thin and high strength disk by the procedure in which a disk body and a thermo plastic resin reinforcing strip material are molded by extrusion and then the hot thermal plastic resin reinforcing strip is continuously thermally fused on the periphery of the hot disk molding.
CONSTITUTION: The thermo plastic resin thin disk 1 is put on the rotary table 2, and the hot thermo plastic resin strip 4 is directed to the periphery of the disk 1 just extruded from the extruder 3 and adhered to the periphery of the disk being rotated in order. In the first place, the strip 4 just extruded from the extruder is directed to the periphery of the disk rotated by the guide roll 5 and then welded to the side or both surfaces at the periphery of the disk 1 by the pressure welding rolls 6 and 7. The strip 4 is of a structure in which only peripheral edge is thicker for reinforcement even if the disk itself is thinner, as shown in Fig.
