Abstract
A rivet pulling head is supported for vertical displacement from an up position to a down riveting position. A rivet delivery device is carried by a movable support and has a delivery arm which can be lowered relative to the pulling head and pivoted underneath it to deliver the next rivet to the pulling head. The delivery device is operated when the head is at the up position and while the head is maintained at that location.
