Abstract

A process and a device for packaging products, particularly cylindrical products such as cigarettes, or the like, in a wrapping sheet, and involves wrapping an ordered group of cigarettes (S) in a wrapping sheet (2) and forming a first tubular wrapping open at its opposing ends and provided with portions (402, 502, 602, 702) projecting beyond the corresponding sides of the group of cigarettes. The ends of the tubular wrapping are closed by the successive folding of the various flaps or various wings (402, 502, 602, 702) forming the projecting portions against the corresponding side of the group of cigarettes (S). The formation of the tubular wrapping open at its ends is carried out in the feed station (A), while the closing of the open ends is carried out completely in only one of the successive stations (P), the whole being done by means of particular shaping, arrangement and operation of movable folding devices (6, 15, 25, 26) and stationary folding devices (5, 105, 205, 605) and of the forming wheel (1).
