A detachable headset, for use with a closure sealing machine for securing a closure to a bottle, has a number of applying or sealing tools, usually in the form of rollers, arranged around its central axis. Each tool is moved inwardly to its operative position, wherein it engages a closure, by means of pressure fluid acting on a piston contained in a cylinder associated with the tool. Each tool may be mounted at one end of a pivoted actuating arm, the other end of which is engaged by the piston associated with the tool. In a preferred construction pressure fluid is led to the cylinders through the application head of the machine to which the headset is attached. |
