Abstract: An automatic device (1) is described for feeding a plastic film (4) for packaging machines (12) with miscellaneous products comprising means for feeding the plastic film (4); gripping and transporting means of the plastic film (4) comprising at least one dragging belt (5) adapted to get in contact with the plastic film (4) and to drag it in a packaging area (6) of the packaging machine (12); and command and control means adapted to unwind the plastic film (4) from the feeding means.

Abstract: A process and a device are disclosed for packaging products in a stretchable plastic film; the device comprises: means for supporting and heating a product; means for supplying and clamping the film in a position overlaying the product; means for contacting and adhering the film, when stretched, to the product; means for cutting the film along its still not-free side; means for locking and releasing the cut film in stretched contact with the product; means for bending and adhering the film to the product through a bending action on the whole product perimeter; means for removing the packaged product; and control means for the device.

Abstract: A device and system for automatically continuously packaging products through a heat-sealed plastic film. The device and system insert and supply the product downstream in a timed way and along a horizontal direction. A plastic film is applied to the products. The first end of each one of the products is heat-sealed, and each one of the products is simultaneously advanced horizontally. A second end of each one of the products is heat-sealed, and each one of the products is then simultaneously advanced horizontally. The heat-sealed products are then collected and unloaded. The device may be equipped with pairs of pliers for sealing and handling with a mutually opposite reciprocating movement.
