ABSTRACT:
A screwcapping machine for screwing a screw closure onto a prethreaded container. The screwcapping machine includes a housing fixed to a stationary support shaft and has a pair of drive motors for independently rotating the turret and the spindles about their own axis. The housing also has a cam which is traversed by a cam follower attached to each spindle which causes the respective spindle to reciprocate. The screwcapping machine further includes a positioning means for selectively orienting the screw closure relative to one of the screwcapping heads when the respective spindle is in a predetermined position and control means for actuating the screwcapping heads to enable the head to grasp the screw closure and tighten it onto the container.
