Abstract

PURPOSE: To improve yield, lower cost and obtain ploughing pawls inexpensively by inserting unit blanks in a pair in rolling rolls to form blade part on one side edge and at the same time guiding the amount of camber on the other side edge to a guide member thereby defining the same.
CONSTITUTION: A strip plate material of rectangular strip form is cut to two single blanks 8 without any waste, and these signal blanks 8 are inserted between the lower roll 10 and upper roll 9 constituted to semicircular form and having blade- forming taper parts 11 by way of guide members 13, 14 until they contact a stopper 12. Next, the rolls 9, 10 are rotated in the arrow c, d directions to form a blade part 4 on one side edge in the width direction of the blanks 8. At this time, a camber is produced toward the other side edge in the width direction and therefore the guide member 14 is contacted to the other side edge to guide the same in the arrow e direction and define the amount of camber to the specified amount. Mounting holes 3 are opened and the work is bent in L form along the bending line 17, whereby the ploughing pawl 1 is obtained more simply and easily as compared to conventional methods.
