ABSTRACT:
A rod, preferably made of metal and partially or completely threaded, is introduced into a body that is preferably wooden and previously drilled, applying a rotary motion at one end of the rod, the rod and the wooden body being thus intimately joined through the effect of self-threading. When one or several rods pass through a number of wooden elements, a very effective union is obtained between the elements. In this way, the mechanical resistance of a piece can be increased and units can be produced through the assembly of elements joined by this method. The units can be articulated about the rod as a pivot. A machine is disclosed which can do the job automatically.
