ABSTRACT:
A mechanism is disclosed for feeding tag stock having spaced-apart drive holes and comprises a pair of slidably mounted carrier arms beneath the tag stock each having a plurality of spring loaded pins on an end thereof. The pins of each carrier arm are alternately brought into engagement with the tag stock by means of a rotating cam which engages a follower on the carrier arm. A pin in each of the carrier arms will alternately engage a hole in the tag stock in registery therewith to sequentially advance the tag stock a desired increment of distance as the cam continues to rotate.
