METHOD FOR OBTAINING MECHANICAL LOCK BETWEEN SURFACES |
摘要 |
A method for obtaining a mechanical lock between two surfaces (10,12) by providing particulate granules (18) between the surfaces and forcing the surfaces (10,12) toward one another at a pressure sufficient to embed a substantial number of the particulate granules (18) in both of the surfaces. The method is preferably utilised during the formation of a hem flange, so as to provide immediate handling strength to the hem flange without the need for adhesive compositions. <IMAGE> |
