<p>PURPOSE: To provide a material supply device in blow molding which is not restricted by a recycling material even though recycling of flashes of a molded product is performed. CONSTITUTION: A pulverized material tank 3 storing temporarily a pulverized material to be obtained by pulverizing a recycling material and a cutting quantity of the pulverized material setting device setting a cutting quantity A2 of the pulverized material per one time a little much more than a mean value A1 of a generating quantity of a recycling material per one time blow molding are provided. Furthermore, a pulverized material supply device 8 cutting the pulverized material at the set quantity A2 when a storing quantity of the pulverized material in the pulverized material tank 3 is at least the set quantity A2 and when the storing quantity does not meet the set quantity A2, the pulverized material is cut down every fixed time, a main material supply device 9 supplying an unused main material and a mixing device 16 mixing up the main material to be supplied from the main material supply device 9 and the pulverized material to be supplied from the pulverized material supply device 8 with each other are provided.</p> |
