ABSTRACT:
A button holder/die assembly in a device for attaching a button to a sheet member, includes a die having a frustoconical portion tapered toward a button support, and a smaller-diameter neck disposed between the button support and the frustoconical portion. The button holder/die assembly also includes a tubular button holder of a resilient material movably fitted over the die for holding a button member. The tubular button holder has a cylindrical wall having one end for supporting the button member and on the opposite end a plurality of radially inwardly extending normally engaging the neck. The tubular button holder can be moved axially onto the frustoconical portion in response to a force applied axially to said one end, while the lips are sliding up the frustoconical portion away from the neck against their resiliency, and can be moved axially away from the frustoconical portion in response to removal of the force, while the lips are sliding down the frustoconical portion onto the neck under their resiliency.
