<p>A mechanism for feeding a ribbon having discrete three dimensional objects includes a specially formed finger which fits through a U-shaped opening from the back side of the ribbon and incrementally drives the ribbon into position where it is severed along a predetermined line by a knife which moves transverse to the direction of movement of the ribbon. The knife includes a gap in the blade opposite the U-shaped opening to avoid severing a tab associated with the U-shaped opening.</p> |
