ABSTRACT:
The method consists in simultaneously press-molding inside a single die a rectangular frame and a transverse movable cross-piece, which have a sliding relationship to each other to form a buckle with a sliding crossbar. Synthetic resins are simultaneously injected in different points into a die after having inserted in the die a sliding separation and coupling means to obtain the sliding coupling of the two piece of the buckle simultaneously with the molding of the same.
