Zusammenfassung:	PURPOSE: An extruding equipment for extruding large sized and double width product having an inner rib is provided to improve the productivity through a small pressure by having a good extrusion property. CONSTITUTION: An extruding equipment for extruding large sized and double width product having an inner rib comprises a port hole(120), a mandrel(110), a flow guide(100) and a die(200). In the port hole, an extrusion billet(B) is divided and flowed in. The mandrel forms a hollow in the billet flowing in and the rear side forms a bearing face(112). An arm fit(113) forming the inner rib in the billet at the mandrel is formed. The flow guide comprises a bridge(111) supporting mandrel between the port hole and mandrel. The die comprises a chamber where the separated billet flowing is fused.
