ABSTRACT:
This invention relates to a process of producing sheets from thermoplastic resins and a screw used therefor. The resin extruder includes a cylinder and the screw. The resin is passed through a feeding section, a compressing section, a metering section, a mixing section, a shearing section and a stress relaxing section, which are successively positioned from a resin feeding side to a resin extruding side, and a molten film-shaped resin is extruded, and this film-shaped resin is passed in a co-current direction with cooling water and is cooled.
