ABSTRACT:
A mold for making a seal for garment labels, the seal including a base body (11) and graft type elements (12) connected to the ends of a cord or thread (10) and insertable into the base body for connecting thereto. The graft type elements (12) engage in a seat (13) through opposite openings in the base body (11) and have resilient fingers (15) which hook into undercuts (14) in the seat (13) to prevent removal. The seat (13) extends longitudinally within the base body (11) and opens at the ends into openings in opposite side walls of the base body each opening defining with the seat an undercut (14) facing the opposite opening. A special mold (16) is required to produce the base body (11) in a single piece by plastic injection and has an internal cavity (24) with a form complementary to the external form of the base body (11) of the seal and into which enter from opposite directions corresponding to the position of the inlet openings in the seat (13) two forming rods (17, 17') each having a form to produce the seat without the undercuts (14) and having a head part (20, 20') shaped to form the undercuts (14) during the molding of the base body (11).
