ABSTRACT:
A machine and method for producing a package by folding a sheet of packing material about a respective article; a packing conveyor feeds along a packing path a folding head, which houses the package and has an electrically heated activating member for applying heat to a portion of the package; the folding head also has a movable magnetic core, which has a coil connected electrically to the activating member, and is positioned facing and coupled magnetically to a fixed magnetic core positioned parallel to the packing path; in use, a coil coupled to the fixed magnetic core is supplied with electric current to induce flow of a corresponding electric current through the coil of the movable magnetic core.
