ABSTRACT:
A turn around device that is designed for changing two side-by-side parallel rows of filter tipped cigarettes, which are formed by a succession of parallel pairs of co-axial cigarettes (S1, S2) with their filters in facing relation, into only one row of parallel cigarettes (S1, S2') with their filters being oriented in the same direction, comprises two fluted, conical, suction, turn around drums (5, 6), of which one takes the cigarettes (S2) forming one of the two cigarette rows, and lays them in a turned around position, i.e., rotated by 180.degree. about a transverse axis thereof, between the cigarettes (S1) of the other cigarette row. Between the point at which the cigarettes (S2) to be turned around are withdrawn, and the first turn around conical drum (5), and between the second turn around conical drum (6) and the point in which the turned around cigarettes (S2') are laid, intermediate transfer device (10, 24) are interposed, consisting of a conical transfer drum (10) and a cylindrical transfer drum (24), of which at least one determines an axial cigarette displacement being adapted for counterbalancing the axial displacement as determined by the conical transfer drums, whereby the turned around cigarettes (S2') will be laid and positioned into alignment with the not turned around cigarettes (S1).
