MACHINE AND METHOD FOR PACKAGING ARTICLES

摘要

A machine for packaging articles includes a frame; a feeder feeding film to a packaging station to wrap articles. A sealing unit includes at least two sealing elements movable relative to each other between a spaced-apart position and a close-together position where the two sealing elements cooperate to seal the film interposed between them. First and second mechanisms having first and second motors move the sealing unit. The second motor is operatively coupled to at least one of the two sealing elements. The first and/or the second mechanisms include at least one articulated arm, respectively. A control unit is operatively connected to the first motor and to the second motor drive them in proper relationship to move the two sealing elements relative to each other and relative to the frame according to a predetermined law of motion.
