Abstract

PURPOSE:To easily obtain a plate spring with eyes, having excellent spring characteristics, by using a combination of four kinds of molds each of which has respective specific molding face in the manufacture of a plate spring with eyes from a fibrous base material impregnated with a synthetic resin. CONSTITUTION:A mold 1 to form a face 107 of the spring of a plate spring 100, a mold 2 to form the periphery of eyes 101, a mold 3 to form the other face 108 of the spring, and a mold 4 to form the inner surface of the eyes 101 are prepared. The mold 2 is rotatably supported on one end of the mold 1, a fibrous base material 110 impregnated with a synthetic resin is placed on the mold 1, the mold 4 is bridged at a given position, and then the mold 2 is turned around a pin 25. And, the free end 111 of the fibrous base material 110 is wound around the periphery of the mold 4, the mold 3 is pressed down, and then they are heated by a heating furnace to cure the synthetic resin in order to obtain an objective plate spring 100 with eyes.
