Abstract (en)
[origin: DE19810367C1] The method involves drilling a hole through the sheets and then using a tapered punch (7) to deform the inner edge of the hole in the upper sheet. The punch is opposed by a die (8) containing a ring (10) to form an eye (9) which is opened over the lower face of the lower sheet by an opposing press (12) to retain the sheets together.
