A method for making an elastically yielding layer (14) on a rigid or substantially rigid support surface (16) of an article (12) comprises a step of providing a support surface (16) inside a mold (18) for injection molding provided with a molding cavity (20), comprising a die (22) and a punch (24). The support surface (16) is in use facing the elastically yielding layer (14). The support surface (16) forms a wall of the molding cavity (20). There is also a step of providing an insert (26) inside the molding cavity (20) and a step of closing the mold (18). A step of injection molding of a thermoplastic polymer above the support surface (16), between the support surface (16) and the mold (18) is also provided.

The invention regards a process for manufacturing a bicycle saddle, which provides a central through channel as well as a hull with a through hole (4′); a polyurethane layer and a liner.

By means of this process it is possible to make sure that, unlike the saddles of the state of the art, said central through channel is completely devoid of the edge present around the aforementioned, with significant advantages from both an aesthetic and functional point of view for the user.
