A METHOD FOR PRODUCING A SPINNING OR TWISTING RING AND A SPINNING OR TWISTING RING.

Application 2362/MAS/1996 published 2006-07-21, filed 1996-12-26
A disc is stamped out as a blank from a steel strip, is provided with a hump in its centre and is deep drawn to form a cup-shaped blank. Subsequently, the hump is pressed flat and, at the same time, material is displaced into the edge zone which forms the flange region. After the pressed-flat bottom has been stamped out, a flange region (70) is formed on the blank (12d) by means of an embossing and deep-drawing die (68) and is brought into the finished shape of a flanged ring by means of an embossing die. As a result of this method, chip-removing machining steps can be avoided and consequently the production costs can be reduced.
