Abstract: A system for manufacturing tobacco products whereby, a number (Pn) that represents a nominal production target for products of a given brand, and a number (Cmax) representing the maximum output capacity of the system, or in practice the maximum quantity of products in process that the system is able to handle, are programmed into master control unit (33). A tally (P) of products is kept, and, at a given moment (t1) following the completion of a number (Pr) of products that matches the target (Pn=Pr+Cmax), a first flash check is run on the quantity (C1) of the product actually turned out by the system; should it emerge from this first flash check that the actual quantity (C1) is equal to the maximum output capacity (Cmax), then a brand changeover procedure will be initiated by the master control unit (33).

Abstract: Production plant featuring automatic making and packing machines, each of which has a relevant control unit; a collection computer awaits receipt of information packages transmitted independently and asynchronously by the control units over a first communication network; and the collection computer organizes and processes the information packages received from the control units to generate overall data accessible over a second communication network, with respect to which the collection computer acts as a server.
