Abstract
An apparatus, such as a filter tipping machine, wherein groups of coaxial rod-shaped articles are connected to each other end-to-end by adhesive-coated uniting strips or bands, employs two endless conveyor belts having parallel stretches defining an elongated rolling channel and moving in the same direction but at different speeds. A first rotary drum-shaped conveyor is employed to deliver successive groups, each of which can carry a uniting band, sideways into the inlet of the channel wherein the groups are caused to roll and the uniting bands are convoluted around them. A second rotary drum-shaped conveyor receives successive groups of interconnected rod-shaped articles from the outlet of the rolling channel and delivers them to a processing station, such as a severing or packing station, or to a magazine. One of the endless conveyor belts is trained over the drum-shaped conveyors.
