Abstract: A conveyor for aligning rod-shaped articles and including a succession of flutes which are movable along a feed path and which are configured to hold respective rod-shaped articles or groups of rod-shaped articles. For each flute, the conveyor has an abutment portion, disposed at least at one end of the flute to define an abutment surface for one end of the rod-shaped article or group of rod-shaped articles housed in the suction flute. The abutment portion is provided with at least one suction zone to hold the end of the rod-shaped article or group of rod-shaped articles by suction against the abutment portion. The suction zone is defined by a plurality of suction perforations, connected or connectable to a negative pressure source and whose transverse size is, for example, smaller than 1 mm, preferably smaller than 0.8 mm and, still more preferably, smaller than 0.6 mm.

Abstract: A device for rolling cigarettes, filter cigarettes or filters, including a rolling channel delimited, at one end, by a rolling portion of a feed conveyor, and at the other end, by a rolling unit which includes an infeed rolling bed and an outfeed rolling bed located in succession along the travelling direction of the rolling channel and defining an infeed stretch and an outfeed stretch of the rolling channel, respectively. The infeed rolling bed is movable along the travelling direction independently of the outfeed rolling bed to produce different rolling modes along the infeed stretch and along the outfeed stretch.
