Abstract: Elongated tubular components are assembled with closures at an assembling station between a first conveyor which delivers properly oriented tubular components and a second conveyor which delivers properly oriented closures. One or more plungers are employed to transfer closures from discrete sockets of the second conveyor onto the adjacent ends of aligned components on the first conveyor. The sockets can receive closures from a web-like carrier which is or can be of one piece with the closures. The transfer of closures from the carrier into the sockets is effected by the pusher or pushers on a transporting device which is driven in synchronism with the second conveyor. The carrier can be drawn from a magazine or is supplied directly by a machine wherein the carrier is formed by providing a strip with a series of spaced-apart closures.
