<p>A method for joining together two or several overlaying sheet formed members (10, 11), metal or non-metal, at which a coaxial arrangement of a punch (12), a die (9) and an anvil (Y) cooperate by means of their relative movement. The punch (12) carries out a first movement coaxially towards said die (9). Thereafter the anvil (Y) moves in the opposite direction. The anvil (Y) is axially blocked and said punch (12) carries out a second movement coaxially towards said anvil (Y) to a position between the anvil (Y) and the punch (12) which is dependent on the applied forces, the thickness, the number and the material of the sheet-formed members (10, 11).</p> |
