Patent number: 6425476Abstract: Flat articles to be formed into groups for packaging are advanced in succession at a set tempo toward a transfer station where each article is made to assume a predetermined position in space, standing on edge. Thereafter, the articles are advanced in a direction perpendicular to the position in space and toward a release station by means of a first conveyor equipped with pockets. The articles are caused to advance at a first linear velocity in such a way that each pocket receives an article and, at predetermined intervals, are accelerated to a second velocity for a predetermined duration between the arrival of one article at the transfer station and the arrival of the next article. In this way, one or more pockets remain empty, and groups of articles forming on the conveyor are separated one from the next by the empty pockets.Type: GrantFiled: January 19, 1999Date of Patent: July 30, 2002Assignee: Azionaria Costruzioni Macchine Automatiche A.C.M.A. S.p.A.Inventors: Roberto Ghiotti, Antonio Gamberini

Patent number: 5782063Abstract: 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.Type: GrantFiled: October 21, 1996Date of Patent: July 21, 1998Assignee: G.D.
