ABSTRACT:
The male component of a press-stud has a dome that extends, so as to form an undercut region, from a first base that is formed by blanking and plastic deformation from a metal plate.
An intermediate tubular element, which is also formed by blanking and plastic deformation from a metal plate, is inserted axially in the dome, affecting part of its internal extension. The intermediate tubular element extends from a second base to be seamed to the first base by folding the perimetric edge of the first base.
A stem protrudes from a third base and has such a cross-section and length as to pass through the intermediate element, perforating the fabric to which the male component of the press-stud is fixed, and to deform against the dome, interposing a wider region between the dome and the end of the intermediate element.
