Abstract

PURPOSE: To improve the accuracy and productivity of scroll laps by disposing an extrusion die between rolling rolls and bending rolls, and passing a strip through the die at its rolling thereby chamfering the corner parts of the strip and shaping and bending the same to required plate thickness.
CONSTITUTION: A strip 6 is rolled to prescribed thickness by rolling rolls 7, and is delivered in a right direction. Next, the strip 6 is passed through an extrusion die 8 by the thrust at the rolling and is further bent by a supporting roll 9 and a transfer roll 10. At this time, the die 8 has a opening part 11, and at the time when the stip 6 passes through the die 8, it is formed to the same shape as that of the part 11, by which it is formed into a sectional shape chamfered at corner parts 2, and is bent to a lap 1.
