An extruder for rubbery materials includes an extruding unit (11) having a die holder (17). A horizontal lead-through groove (19) is formed in the die holder for slidably arranging a die plate (20) therein. A rubbery material is extruded through the die plate in a predetermined direction to form a strip rubber member (22) with a predetermined cross-section. A storing means (95) is arranged one side of the extruding unit (11), for temporarily storing a plurality of types of die plates (20) to be subsequently used on a storing table (43) in accordance with a predetermined use priority. The storing means delivers a next die plate from the storing table to a waiting position (T) along the extension line of the lead-through groove (19). A moving means (127) is operative when the die plates (20) are to be changed, for moving a current die plate together with the next die plate at the waiting position (T), along the lead-through groove in a direction toward the other side of the extruding unit. The moving means thereby ejects the current die plate from the lead-through groove and moves the next die plate to an extruding position (S) in the lead-through groove. <IMAGE> |
