ABSTRACT OF THE DISCLOSURE A stamping apparatus is disclosed for deforming 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 slower or faster by angular speed than the rotor, the resulting angular speed differential being utilized to effect the rotation of the stamping rolls on their axes.
