Abstract

Each of supply meansarranged around an extrusion portof an extrudersupplies, while cutting a molten resin which has been extruded from the extrusion portof the extruderalternately in a predetermined length, the molten resin D which has been cut to a supply position which is provided at each of the supply means, and then sequentially supplies the molten resin D to each of a compression molding dieswhich are provided in a pair with each of the supply means. As a result, in producing a synthetic resin molded article with a predetermined shape by compression molding by cutting a molten resin which has been extruded from an extruder and supplying the resin which has been cut to a compression molding die, the above-mentioned constitution can be preferably utilized for the production of a synthetic resin molded product which requires a further high load. In addition, by this constitution, not only a molten resin can be supplied to a compression molding die with a sufficient accuracy, but also the positional accuracy of the supplied molten resin is prevented from being impaired after the resin is supplied to the compression molding die.
