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