Abstract

PURPOSE:To remove retention in a screw head, and to prevent curing due to thermal deterioration by supporting a nose section of the screw of an extruding machine by the die plate. CONSTITUTION:A resin raw material is melted by means of a double spindle extruding machine 1, and a mixture is homogenized and supplied to the single spindle extruding machine 2. The single spindle extruding machine 2 transports forward the resin raw material, in which the melted mixture is homogenized, through the revolution of the screw 3, and the raw material is discharged in a stringy shape from the die plate 5 with nozzles 4 for discharging the raw material mounted to the nose section, and cut in a uniform granular shape by means of a cutter 6. A hole 10 for cooling is formed to an axis of the screw 3, and the heat of the resin raw material from the inside of the screw is removed. Accordingly, the nose section does not swing because the screw 3 does not turn as it is left as it is open-sided as seen in conventional devices, heat from the inside is taken away and the raw material does not stay at the nose section of the screw head.
