Abstract
At a certain stage in the fabrication of a rigid cigarette packet, which appears essentially as a rectangular cup or body with a coaxial lid, the partly formed packet is transferred from a first feed path onto a second feed path, still having longitudinal flaps that project on either side from a front face of the body and a front face of the lid; the transfer is effected by means of a device that includes in a rotatable platform with at least one gripper head designed to engage at least the two front faces of the single packet in such a way that the body and lid remain stably interconnected, and during the course of the transfer movement to rotate the packet through 90.degree. about an axis which is normal to the front faces.
