Abstract
The invention relates to a method for making a building board 2, exhibiting a board body S which is formed with a gripping stud 24, and a metal strip 10 which extends from the body S and from which are formed gripping elements 26, 28 which are bent round the gripping stud 24 for mechanical fastening of the strip 10 TO the body S, as well as locking element 12 for enabling mechanical joining of the board 2 to similar boards. The method is characterized by preforming the gripping elements 26, 28 of the strip 10 prior to bending them round the gripping stud 24, and subsequently bending the preformed gripping elements 26, 28 round the gripping stud 24, the preforming being such that, as a result of the bending, the preformed gripping elements 26, 28 strike against the gripping stud 24 and thereby undergo a deformation in the opposite direction to the preforming during a final stage of the bending.
