Abstract (en)

A machine and a process for packaging products by wrapping a stretchable transparent film of plastic material around the products placed in trays of different sizes. Trays (20) carrying the products are advanced transversally with respect to the plastic film (18) that unrolls from one or more supply rolls (11, 12, 41, 42) and is cut at prefixed and adjustable lengths and then further advanced to be centered over the tray. The machine carrying out the process includes a control unit performing portions of the packaging cycle that are common to every tray and portions of the cycle dependent upon the size of the tray. The sizes of a series of trays are preset by the operator, e.g. positioning a selecting device on one of the possible values that are provided by the machine. Moreover the machine provides for a plurality of film supply rolls (11, 12, 41, 42) mounted on both sides thereof and having different width for an alternating use so as to reduce the time for changing or replacing a film roll. Conveyor means for the film comprise elastic endless cords, movable on rolls transversally displaceable to fit the different film widths.
