Abstract
A fastener apparatus, which attaches a first article to a second article at a setting station, includes a plate-like support, a feed in finger for receiving and engaging a first article at a first predetermined position, and a lever pivotally mounted on the support and pivotally connected to the feed in finger. A spring continuously urges the lever to pivot to move the feed in finger along a substantially horizontal predetermined path from the first predetermined position to a second predetermined position at the setting station. A cam surface of a cam element, which is vertically movable in response to vertical movement of a ram housing, acts on a roller on the lever for rendering the spring ineffective and for moving the feed in finger from the second predetermined position to the first predetermined position. A die, which is connected to the ram, engages the first article at the second predetermined position after the feed in finger has been moved from the second predetermined position to the first predetermined position with the die moving the article substantially perpendicular to the predetermined path to move the first article into engagement with a second article at the set…
