ABSTRACT:
A rotary type capping apparatus for screwing caps onto the mouths of containers includes a turn table provided with a plurality of container holders fixedly mounted along the periphery thereof, a main motor for rotating the turn table in a predetermined direction and a capping head assembly including a plurality of cap holders, each of which is disposed above the corresponding one of the plurality of container holders, so as to be movable closer to or away from the turn table. In one aspect of the present invention, the capping apparatus includes at least one motor exclusively used for rotating the cap holders for causing the caps held by the cap holders to be screwed onto the mouths of containers. In another aspect of the present invention, the capping apparatus is so structured to increase the torque applied to a cap until it has reached a predetermined level during the cap screwing operation thereby insuring that all caps may be screwed on as tightly as desired.
