ABSTRACT:
Method for the manufacture of a nail element comprising a plate-shaped body and one or more elongate elements whereby in accordance with the invention in each case at least one elongate elements is set at an angle relative to the face of the plate-shaped body and brought into contact with it, whereupon heat, for example from electric resistance welding, is generated at the point of contact for melting the material of the elongate elements and the plate-shaped body in order to weld these to each other, so that a nail element may be obtained in a simple manner and inexpensively.
