摘要： Machine for packaging products with stretch film the flaps of which are stretched, folded and mutually superimposed on the bottom of the product usually arranged in a tray, comprising a final station with a motorized heat-sealing conveyor to mutually secure said flaps with a heat-sealing operation, characterised in that this final heat-sealing station is provided with an upper protective chamber for the operator, and which limits the loss into the work environment of heat produced by said heat-sealing conveyor, now incorporated in this protective chamber, which has a shape and size such as to allow the packaged products to be conveyed therethrough without interference, this protective chamber being provided with an inlet opening usually communicating with the casing of the packaging machine and being provided with an outlet opening for conveying the packaged products, wherein at least this last outlet opening is closed by a swinging barrier that prevents loss of heat towards the outside and that is arranged to swing and open only in the direction of normal flow of the packaged products and due to the thrust of these latter, but which cannot swing in the opposite direction, to act also as safety barrier, said protective chamber being provided on at least one of the walls not involved by said swinging barriers and in view, with at least one window closed by at least one door preferably made of transparent material, which in the open position allows the operator to rapidly remove the packaged product optionally stationary on the heat-sealing conveyor, there being provided safety means to automatically shut down at least the power supply to this heat-sealing conveyor when said door is opened.
