A method of exchanging a preheated die holder of an extruder for elastomers, said extruder having a clamp and a recess on a die head portion to hold a die holder, comprising the steps of: unclamping a die holder installed in said die head portion by releasing said clamp and downwardly extruding a small amount of elastomer; cutting the elastomer with a cutter knife, and receiving the die holder thus released, placing a preheated die holder on a table of a movable car, said table being capable of vertical movement, aligning said preheated die holder with a blank space between said recess and said clamp when said clamp is placed in an intermediate position, transferring said preheated die holder into said blank space by movement in a longitudial direction, and fixing said preheated die holder with said clamp.
