Abstract
A method of forming groups of cigarettes, each group being defined by at least one layer of cigarettes arranged side by side. The layer is fed continuously at a given speed and by means of a conveying seat along a given annular path extending through an unloading station. At the unloading station where the layer is transferred from the seat to a group forming pocket (6) by orienting the seat with respect to the path as a function of the relative position of the seat and the pocket (6) at least at the unloading station.
Claims14
A method of forming groups of cigarettes, each group comprising at least one layer of cigarettes arranged side by side, wherein the method comprises a step of continuously feeding said layer at a given speed and by means of a transfer device comprising a carrier and a conveying seat movable on the carrier for transporting the conveying seat along a given annular first path (P2) extending through a supply station where the layer is fed into the conveying seat, and through an unloading station, the first path (P2) being substantially tangent to a second path (P1) at the unloading station, with the conveying seat being oriented from an initial position on the carrier to a second position at least at the unloading station;
- a step of continuously feeding a forming pocket along the second path (P1) and through said unloading station in time with said conveying seat;
- a transfer step whereby said layer is transferred from the conveying seat to the forming pocket at said unloading station;
- and an orienting step whereby said conveying seat is oriented with respect to said carrier as a function of the relative position of the conveying seat and the forming pocket at least at said unloading station.

- an orienting step whereby said conveying seat is oriented with respect to said carrier as a function of the relative position of the conveying seat and the forming pocket at least at said unloading station;
- and a layer compacting step whereby said conveying seat is oriented when partially enclosed in said pocket.
