PROBLEM TO BE SOLVED: To smoothly start an extruder by overcoming the deformation resistance of a low-temperature material when the continuous extruder is started and to extrude a large-diameter material or a material of large deformation resistance with a small extruder of relatively small driving torque by reducing the load of a rotating wheel driving motor. SOLUTION: This continuous extruder is equipped with a rotating wheel 1 having a ring groove 2, a fixed shoe block 4 which is arranged against a part of the outer peripheral surface and forms a passage 6 for passing a wire- like material 5 between a part of the groove 2 and the block, an end portion 7 to close the end of the passage, and dies 8 for continuous molding which are opened into the passage 6. In this case, a heating means 14 to heat the rotating wheel 1, with which the material 5 is brought into contact, is provided and is operated before starting the extruder.
