Containers are transported on rotatable support plates which are arranged in a circle on a rotating turntable. The leading edge of a label is adhered to a container as it orbits past a vacuum-type label transfer drum. A curved guide which is tangential to the cylindrical body of the container as the orbiting and rotating container passes it causes the label to wrap completely around the container. One of a circular array of heat sealing elements which are rotating with the turntable adjacent each support plate is cammed radially outwardly of the turntable into contact with the region on the container where the trailing end overlaps the leading end of the cable. This fuses the ends of the labels together. The cam profile is adjustable in length to keep the time during which the heat sealing member is in contact with the label ends overlap constant independently of the rotational speed of the turntable.
