Separator drum

A separator drum for tobacco industry product assembly apparatus, the separator drum comprising a plurality of segments arranged in first and second rows extending about the circumference of the separator drum to form at least a part of a peripheral surface of the separator drum, each segment in the first row of segments being aligned with a segment in the second row of segments in an axial direction to form a pair of segments, wherein each segment of the separator drum comprises at least one flute and at most three flutes, and wherein the flutes of each segment are aligned in the axial direction with the flutes of the other segment in each pair of segments, each flute being adapted to carry a rod of aerosolisable material as the separator drum rotates during use, and wherein each segment is slidably mounted to the separator drum for axial movement between a first position in which the segment is proximate to an adjacent segment of the second row of segments, and a second position in which the segment is axially spaced from the adjacent segment of the second row of segments, wherein each segment comprises a first linear bearing disposed on a first side of the segment, and second and third linear bearings disposed on a second side of the segment, and wherein the first linear bearing is axially offset from the second and third linear bearings.
