Abstract: Method to control the interference and/or collision between mechanical members of at least two operating or one operating unit with respect to fixed positions. At least one operating unit is associated with a position detector or with a position simulator, and is equipped with an electric which drives a mechanical member. The method is managed by a management and control unit. The control of the operating units occurs in two phases, verifying point-by-point the position of the mechanical member as a function of the current dynamics and the braking or acceleration times and spaces (first phase), and verifying the intensity of point-by-point current supplied to at least one electric motor (second phase).

Abstract: A device is provided for winding an envelope (A) around a product (B), such as a group of cigarettes or the like. The product is to be packaged in a corresponding box-shaped body, or packet. The device includes an apparatus (10) for winding the envelope (A) around the product (B) and an apparatus (20) adapted to supply the product (B) and the envelope (A) to the winding apparatus (10).

Abstract: A packet is suitable to contain products in loose or organized form and comprises at least two elements such as a mobile lid, affecting the upper part of the packet, and a containing body. The containing body consists of two lateral, a rear wall, a front wall, an upper wall and a lower wall, all defining a front bulk and a lateral bulk. The elements are connected to each other by movement means. The mobile lid is suitable to assume a closed position and an open position. The mobile lid, the walls of the containing body and the movement means define a kinematic mechanism suitable to make the mobile lid assume an open position as well.

Abstract: Method to command and control an electric motor of an automation unit. The unit comprises a mechanical member, driven by a drive shaft, a central command and control unit, and a position detection mean. The method provides that the central command and control unit receives the position signals of the shaft of the electric motor and/or of the mechanical member from the position detection mean, divides the operating cycle into a plurality of sub-phases equal with respect to each other, consisting of elementary units and, for each of said sub-phases, or multiple of sub-phases, selects predefined or self-learnt current reference values, and generates a signal consisting of an instantaneous current reference (feed forward) for the electric motor.
