Abstract
A capping chuck assembly embodying the present invention comprises an outer chuck housing, and inner, central guide disc upon which a plurality of circumferentially spaced gripper segments are mounted. Each gripper segment includes an inner jaw portion for engagement with an associated closure, and an outer cam surface. The outer chuck housing defines a plurality of inwardly facing, cam drive surfaces positioned for respective engagement with the outer cam surfaces of the gripper segments, so that rotational drive of the outer chuck housing collectively drives the gripper segments and guide disc to urge the segments radially into engagement with an associated closure.
