ABSTRACT:
A stamping apparatus disclosed deforms a filamentary material to provide coupling heads and the like at predetermined intervals along the length of the filament which is to be coiled and attached to stringer tapes for a slide fastener. The apparatus includes a pair of stamping rolls which are rotatable in opposite directions on their own axes simultaneously as they orbit about the axis of a rotor. A ring member rotatably connected to the stamping rolls is driven via the same power source as the rotor but rotates at a slower or faster angular speed than the rotor, the resulting angular speed differential being utilized to effect the rotation of the stamping rolls on their axes.
