<p>Method and apparatus for joining superimposed sheet formed material with an intermediate layer of adhesive together by means of gluing in combination with clinching, at which a tool comprising a first and a second co-axial tool parts, co-operate for producing said joint, said first tool part comprising a punch (1) with an impact surface, surrounded by a stripper (2) with an impact surface, said second tool part comprising a die with an impact surface surrounding a die cavity at the bottom of which an anvil with an impact surface is arranged. In a step before making the clinch joint positioning and locking said punch (1) and said stripper (2) of said first tool part relative to each other so that said impact surfaces present a first, common, squeezing surface (6) of the first tool part, having essentially the same size and form as a second, squeezing surface of the second tool part. Then squeezing together the work pieces (9, 10) with the intermediate layer of adhesive over a surface corresponding to said squeezing surfaces in order to laterally displace excessive adhesive out from the corresponding area of the work pieces.</p> |
