<p>A packaging machine for packaging different products (16) with heat-shrinking plastic film (13) comprises means (12) for cutting and sealing the film (13) and a tunnel (14) to cause the sealed film wrap applied to the product (16) to be packaged to undergo heat-shrinking. Said cutting/sealing means (12) are installed between a first conveyor means (15) for product (16) entry and a second conveyor means (17) which receives said product (16). Said heat-shrinking tunnel (14) is positioned under said first conveyor means (15) and through said tunnel (14) a third conveyor means (19) is installed for driving the packaged product (16) to exit the packaging machine. Said second conveyor means (17) can be vertically reciprocated from a first, raised position in which said second conveyor means (17) is co-planar with the first conveyor means (15) to a second, lowered position, in which said third conveyor means (17) is co-planar with the third conveyor means (19), and vice-versa. <IMAGE></p> |
