Abstract
A capping device fits caps onto containers by applying an axial force to the caps as they are threaded onto the containers. The capping device utilizes a drive member rotatable about an operational axis for imparting rotation to a capper body slidably coupled to the drive member. A helical spring urges the capper body away from the drive member with a biasing force. A bearing mechanism allows relative free sliding movement of the capper body relative to the drive member. The bearing mechanism includes a plurality of bearing members. In one embodiment, the bearing members are bushings. In another embodiment, the bearing members are ball bearings.
