Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a strip rubber extruding apparatus capable of extruding a thin strip rubber without requiring high pressure while suppressing making the equipment large-sized in the extrusion of the thin strip rubber. SOLUTION: The strip rubber extruding apparatus 1 extrudes the strip rubber S having a prescribed cross-sectional shape through a molding sprue 2, wherein a wall surface forming a rubber flow path in the molding sprue 2 is composed of a movable member capable of rotating in the strip rubber S discharge direction. The movable member is preferably a pair of cylindrically shaped rollers 20. Gears 20b are more preferably formed on both end parts of each of a pair of the cylindrically shaped rollers in the width direction. The movable member is preferably a pair of spherically shaped rollers 22. COPYRIGHT: (C)2009,JPO&INPIT
