The illustrated apparatus includes a plunger and a cooperable anvil between which a tag and merchandise are positioned and through which a fastener specifically a pin is driven to attach the tag to the merchandise. While the pin is being driven through the tag and merchandise, a movable pin guiding and crimping member moves relative to the plunger, the tag and the pin. The pin is driven firstly through the tag, secondly through the merchandise, thirdly through the merchandise again, fourthly through the tag again, and fifthly through the tag again, and thereupon the movable pin guiding and pin crimping member is moved again to crimp the pin. A bottom tag in a stack is separated by feeding it toward the pinning zone in one machine cycle and the separated tag is positioned between the anvil and the plunger during the early part of the next machine cycle.
