Abstract
A machine to cover articles with flexible plastic material sheets. The machine includes an assembly for heat-sealing and cutting the sheets which cooperates with a work surface. The assembly includes a first and a second element, of which at least the first element is movable with respect to the other, and the two elements being arranged on opposite sides of the work surface. The first element includes a cutting and sealing blade having an electric current which passes through it and the second element including a cutting and sealing counter blade. Operation levers are provided to move the cutting and sealing blade from a rest position to a work position where the cutting and sealing blade engages the cutting and sealing counter blade. The first element and the levers belong to a unit connected to the work surface in a removable manner. The unit also includes elastic portions for holding the blade at a rest position.
