ABSTRACT:
There is disclosed a capping machine head for affixing screw caps on containers, which in one embodiment has a cylindrical magnet ring in the body of the head surrounding a cap chuck driving element in a low friction bearing in the head, each having an array of permanent magnets distributed around their periphery. For certain angular relative positions of the ring and the chuck driving element, the North poles of one are face-to-face with the South poles of the other; displacement from such position causes torque on the order of ten to twenty inch pounds to be imparted to the chuck driving element. The chuck driving element rotates with the magnet ring until the resistance of a cap being threaded on the container exceeds a predetermined torque limit, after which the magnet ring rotates relative to the essentially stationary chuck driving element. The ring magnets may be in an axially misaligned position to reduce and control maximum torque value. Preferably the flux pattern of the magnets is elongated in an axial direction, by providing two rows of cylindrical magnets, or magnets which are elongated in that direction. The spring for urging the chuck downward is fully contained within the head. In some magnet arrangements torque is produced by both attraction and repulsion, and in others it is produced by attraction only.
