Abstract

PURPOSE: To manufacture the large size spiral sheet at high efficiency, by pressing the sheet material cut into a ring type and being sent forward successively into the clearance between the lower dies and the freely vertically movable upper dies, both being provided with the pressing planes of a specified shape.
CONSTITUTION: The upper dies 4 and lower dies 5, both being provided with the pressing plane consisting of inclined curved plane of a specified shape, are set in the press machine; the sheet material 3 is prepared by blanking into a ring type and by cutting radially a part so as to form the cut ends; thus prepared sheet material 3 is set on the lower dies 5. The sheet material 3 is sent forward successively while being turned round, and the upper dies 4 is continuously moved up and down for executing the press work; hereby, the specified shape spiral sheet 3' is formed to one pitch. Suitable number of thus prepared spiral sheets are jointed by welding; hereby, the spiral blade for use of the spiral classifier, screw conveyer, etc., can be easily manufactured.
