Machine for wrapping substantially parallelepiped box elements
 A machine for wrapping substantially parallelepiped box elements, typically packs of cigarettes, comprises a push rod by which each box is directed against a respective wrapper of heat-sealable material, and directed together with the wrapper into a pocket, also folders by which the wrapper is closed into a tubular sheath around the box, and a heat-seal device by which the overlapping edges of the wrapper are secured to one another. The folding and heat-seal steps both take place while the box remains positioned in the pocket, with the folders and heat-seal device operating sequentially and in such a way that the overlapping extremities of the wrapper are secured before bring released by the folders, thereby ensuring that the wrapper remains taut.
