An actuation unit for a capping head for the application of caps on containers or bottles, as well as to a capping head using such a unit, are provided. The actuation unit for a capping head for the application of caps on containers or bottles comprises at least two actuators, of which a first actuator is adapted to impart a translational displacement along a closing axis and a second actuator is adapted to impart a rotational movement about the closing axis, each actuator of the at least two actuators causing the rotation of a first shaft and a second shaft, respectively, both arranged coaxial to the closing axis, and is characterized in that the shafts of the at least two actuators are placed side by side along the axis and are mutually connected by means of at least one rotation decoupling joint.

Actuation unit for a capping head and capping head using it

A magnetic coupling device () is provided for coupling a first member () and a second member (), coaxial with each other, so that they can jointly rotate about a common axis and/or translate along such axis or can perform relative rotary and/or translatory movements depending on the intensity of a torque or an axial force applied to one of the members. At least one of the members () has axially extending magnetized areas () each consisting of a row of axially aligned magnets ('), the magnets (&#x2032;) in one area () being axially offset relative to the magnets of an adjacent area ().
