ABSTRACT:
A press for manufacturing helical gears having a punch with a cutting edge; a die with a cutting edge, one of the cutting edges being shaped as a helical gear and the other having a shape corresponding to the shape of the one cutting edge; and a bolster rotatable about an axis and provided with one of the die and the punch. The die and said punch are pressed together and the bolster is rotatably driven by a driving element in response to a lead of a helical gear to be manufactured. The stroke of the punch is detected and a desired rotation angle of a driving element is calculated and then signalled to the driving element.
