ABSTRACT:
Male or female annular components of fasteners are applied to articles of clothing in a machine wherein the lower tool of a pair of confronting tools has a socket for reception of the heads of discrete rivet-like connectors whose shanks extend upwardly toward the upper tool which has tongs with jaws for releasably holding a male or female component in such orientation that the central aperture of the component is in register with the shank of the connector in the socket of the lower tool. The upper tool further includes a ring-shaped hold-down device for the male or female component which is held by the tongs as well as a deforming plunger which can upset the tip of the shank after the latter has penetrated a garment between the two tools and thereupon through and partly beyond the aperture of the component in the tongs in response to downward movement of the upper tool. The hold-down device is movable axially relative to the tongs and the plunger is movable within limits axially of the hold-down device. The male and female components of fasteners are stored in discrete magazines and are fed to the tongs by devices whose operation can be blocked so that the tongs receive male or female components.
