Abstract

PURPOSE: To enable rapidly production of a spiral screw by the steps of feeding a band steel plate obtained in a hot rolling step to a spiral screw winding and forming step and winding the band steel plate on the outer periohery of a core.
CONSTITUTION: To manufacture a long spiral screw 1 for the auger screw of an earth auger, a band steel palte 2 is first hot rolled as a spiral screw 1, the plate 2 thus treated is immediately sequentially wound on the outer periphery of a core metal 3, and a thin edge 4 is added to the outer diameter portion of the screw 1 by this forcible winding process. After this screw 1 is coated on a torque tube 5 and welded at one end 1' thereof at the position designated by 6, it is elongaged in the direction of an arrow a at the other end side, and welded at the respective portions when becoming predetermined pitch p to thereby obtain desired auger screw 7.
