<p>In a method for riveting materials using a blind rivet, the body of the tube (31) is drawn before being held at each end in an assembly (13, 14) between a pressure head (50) and a holding head (51). Extension of the tube body is made possible particularly by the cooperation of a contact means (44) with a shoulder (36a) of the forming stem (32), and by the pull on the stem. Blind rivets suitable for this method are also described.</p> |
