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 driv e 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 fro m the drive member with a biasing force. An adjustment mechanism adjusts the biasi ng force thereby adjusting the axial force applied to the caps as they are threaded onto the containers. A pair of retaining pins move between a latched position to prevent adjustment of the biasing force and an unlatched position to allow adjustmen t of the biasing force. The retaining pins are biased in the latched position to prevent inadvertent adjustment of the biasing force during use. |
