Abstract
A method of overwrapping packets of cigarettes is implemented utilizing a machine by which packets and respective sheets of wrapping material are fed singly and in timed succession to a folding station where each packet is directed against a central portion of the corresponding sheet and advanced together with the sheet through a tubular duct of proportions such that the sheet is constrained to fold into a U formation around the packet. To optimize the folding action, the duct is fashioned with two longer side walls of convex profile by which the two lateral portions of the sheet flattened over the main lateral faces of the respective packet are engaged and compressed only along a limited central band of their full advancing width, and caused as a result to spread gradually into uniform contact with the overwrapped surfaces, without creasing.
