An apparatus of the tobacco industry for the rejection of defective rod-like articles from a mass flow of rod-like articles, comprising a monitoring unit (100) adapted to optically determine geometrical parameters of rod-like articles (R), and at least one rejecting unit (200) adapted to remove a rod-like article from the mass flow (M) of rod-like articles (R), wherein the mass flow (M) being transported on the conveyor (10), such unit (200) being situated behind the monitoring unit (100) with reference to the direction (T) of the mass flow (M) of rod-like articles (R). The apparatus is characterised in that the monitoring unit (100) has optical recorders (101) recording images of opposite side surfaces of the mass flow (M) of rod-like articles (R) on a conveyor (10) wherein said side surfaces are formed by front surfaces or rod-like articles (R). The apparatus comprises the controller (300) which basing on the recorded images, using the criteria concerning geometrical parameters of the opposite front surfaces of rod-like articles (R), identifies defective rod-like articles (Rd) in the mass flow (M), and determines the position of the defective rod-like articles (Rd) in the mass flow (M), and the rejecting unit (200) comprises at least one rejecting element (201, 203, 204, 205, 205) adapted to reject the defective rod-like article (Rd), the rejection unit (200) being mounted in such a way that it moves along together with the mass flow (M) in a position enabling it to reject the defective rod-like article (Rd).

The invention relates to a hopper (10) for rod shaped articles (100) defining a longitudinal axis, the hopper (10) including: a chamber (20) to hold the rod shaped articles (100); a distributor device (30) to align the rod shaped articles (100) with substantially parallel longitudinal axes, the distributor device (30) including a plurality of walls (50) defining adjacent channels (40), at least one of said walls (50) including a stationary part (51) and a movable part (52) connected to the stationary part (51); and a vibrating device (70) adapted to oscillate the movable part (52) with respect to the stationary part (51).

A method for producing packs for cigarettes, in which at least one group of cigarettes is wrapped in an inner wrapper and is introduced into a pocket of a folding turret and therein is packed in a blank for the pack, and a corresponding apparatus and to a pack for cigarettes. At least one dimension of the at least one cigarette group does not correspond to the respective dimension of the interior space of the pack, the at least one deviating dimension is equalized by at least one filler piece, and the at least one filler piece is wrapped in the inner wrapper conjointly with at least one cigarette group.

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.

Method to feed and form organized groups of smoking articles, providing to feed a plurality of pockets of a transfer conveyor with pockets moved step-wise, thrusting said organized groups of smoking articles, by means of thrusters actuated independently from each other, in a direction of transfer and through respective forming drawers, into said pockets on the basis of a predefined production rhythm. The method provides, in the event of obstruction, stoppage or blockage of a forming drawer, to vary the operating speed of the thrusters associated with the other forming drawers in coordination and in synchrony with the step-wise feed speed of said transfer conveyor with pockets, in order to obtain an effective production rhythm equal or near to said predefined production rhythm.
