Abstract
Capping head assemblies that are useful for applying pre-threaded closures onto containers with improved sensitivity.The novel features of the devices are a simple and novel means of adjusting the torque in a magnetic clutch assembly. In addition, the advantage of preventing contamination by water and other liquids during the filling and capping of liquid containers, and further, have the capability of being greased without having to disassemble the device. In addition, these can be accomplished without changing the capability of being able to read the adjustment scales on the outside surface of the magnetic clutch assembly and the adjustment scales on the outside surface of the upper spring assembly for adjusting the tension in the spring.
