ABSTRACT:
A device with a packaging wheel, for supplying sheets, in particular in cigarette packaging machines, comprises means (20, 20') for collecting/positioning the packaging sheets (F) in a predetermined position, in a transfer station (T), between a cell (101) of a transfer drum (1) which accomodates a group of cigarettes (S) and an empty cigarette-carrying cell (102) of a folding drum (2) opposite. During transfer into the cell (102) of the folding drum (2), the group of cigarettes (S) draws the sheet (F) which is folded automatically in a U-shape around the cigarettes (S) by the cigarette-carrying cell (102). According to the invention, the collecting/positioning means (20, 20') consist of mechanical gripper means for grasping the packaging sheet (F) which are provided at least on the front side of each cigarette-carrying cell (101) of the transfer drum (1), with reference to the direction of rotation of the drum.
