摘要：This invention relates to a rotary kneading screw installed in an extruderkneading and extrusion-molding a material mixture of a synthetic resin such as polyesterresin mixed with one or more of master- batch, calcium carbonate, talc and carbon fiber.Progressively higher pressures are applied to the material mixture passing through akneading section defined in the rotary screw. This rotary kneading screw is thus capableof kneading and extruding the material mixture in a large amount without deterioratingits physical properties and without lowering fluidity and molecular weight thereof evenwhere the material mixture is difficult to knead.
