Abstract: A capping machine for applying removable closures to bottles, jars or other containers has a capping head cantilevered (without other support) from a post rising from the machine base, the capping head height being infinitely variable by simple adjustment. The side belts which engage the containers are also infinitely variable for height, being carried by a parallelogram structure pivoted on the capping head body and adjustable by means of a single nut. The cap chute has a pair of retractable rollers to locate the closures at the pick-up point, these rollers being mounted on tension-spring biased cranked levers so pivoted that their lever arm, for movement of the roller axes, makes only a small acute angle with the path of the closures. The sealing shoe is suspended in the capping head by a pair of levers which permit the shoe to rock in a vertical plane.
