ABSTRACT:
Apparatus for producing composite filter plugs for cigarettes or other smokers' products has two sets of conveyors which feed filter rod sections of different types to the flutes of a rotary assembly conveyor. The latter assembles the sections into groups each having a section of first and second type and moves the groups to an auxiliary conveyor which transports the groups sideways to successive pneumatic holders of a transfer conveyor. The transfer conveyor has two carriers which rotate about parallel axes and are coupled to each other by linkages, one for each holder. The linkages cause the holders to rotate relative to that carrier which supports the holders so that the orientation of holders remains unchanged during travel through 90.degree. or 270.degree. when the groups are taken over by successive increments of a web which is moved lengthwise and is draped around the resulting rod-like filler to form therewith a rod. The rod is severed to yield composite filter plugs each having a section of the first type and a section of the second type.
