摘要： A screw extruding machine for extruding a material such as rubber, plastics or the like kneaded and blended into a sheet-like form. The screw extruding machine includes two screws horizontally and rotatably supported on a casing, a top-open hopper provided on the side of a screw base portion of the casing, an outlet opened in an axial direction of the screw on the side of a screw front end of the casing, and a roller die in proximity of the outlet, the screw having a feed portion which corresponds to a portion facing the hopper and a compression portion which corresponds to a front end side, whereby material to be extruded supplied from the hopper is extruded into a sheet-like form by the roller die from the outlet via the feed portion and the compression portion by the rotating twin screws, the hopper being positioned over the feed portion of each screw.
