Abstract

A packaging machine using extensible film for products fed in groups or individually includes a conveyor feeding the product, a product positioning unit, a film winding unit and a discharge conveyor positioned at the outlet of the winding unit. The winding unit is a ring winder having a ring rotating with respect to guiding rolls, positioned on a supporting frame, and arranged on a plane perpendicular to the advance direction of the products. A shelf is provided beneath the winding unit, cantilevered for extending in the advance direction of the products, and connects the feeding conveyor with the winding unit. A vacuum-effect gripping unit is positioned beneath the shelf for gripping the film and carries a cutting unit. The vacuum-effect gripping unit and the cutting unit can be moved alternatingly and selectively from a withdrawn rest position of the shelf to an extended position for gripping and cutting the film.
