Abstract
A finger assembly for a rotatable screwcapping head which is capable of gripping and screwing a screw closure onto a prethreaded container. The finger assembly includes a guide member which retains at least two fingers pivotally positioned thereon. The fingers have a concave surface which is capable of gripping the screw closure as the fingers are moved to a closed position. A pair of C-shaped retaining rings encompasses both the guide member and the fingers and serves to secure them to the rotatable screwcapping head. The finger assembly also includes an actuator for pivoting the fingers between a closed position wherein the fingers grip the screw closure and an open position wherein the fingers release the screw closure.
