Abstract
For placing prethreaded closure caps on the mouths of screw threaded bottles and effecting preliminary engagement of the caps with the threads of the bottles, the caps are withdrawn successively from a feed chute and supplied to suction pick-up members, which are individually supported by brackets, turning about the center of a star wheel. The brackets are supported by a cam track which raises and lowers the suction pick-up members, which carry the caps on their lower surface. The caps are thus lowered onto the bottles in a level condition and are held level by the pick-up members during preliminary engagement of the caps with the bottle threads. The caps are conveniently rotated by rotating the pick-up members in their brackets through contact with a stationary friction or rack member.
