Abstract

PURPOSE:To obtain an extruder with roller die, having a proper pressure distribution for extruding materials and to omit (or shortened) a metering part, by providing a screw to be operated under a specific condition to the extruder. CONSTITUTION:In a cylinder 1, a screw 2 consisting of a feeding section 21 and a compression part 22 is held rotatably in one-side supported manner at two points by a bearing 5 and an external bearing, and also roller dies 4 are provided through a bank 7 to make up an extruder with roller dies. By such an extruder, a rubber or plastic material is molded by extrusion into sheets while keeping maximum pressure in the compression part at 52-200X10<3>g/cm<2> and also pressure at the top of the screw at 20-60X10<3>g/cm<2>.
