Abstract: A film gripping and releasing device for pallet wrapping machines of the type with a turntable and a fixed frame, comprises a gripper and movement means for the gripper on board the table, and a movable contact element constrained to the frame. The movable contact element can go from a retracted home position to an operating position projecting from the frame, and vice versa. When the contact element projects from the frame interacts with the movement means for the gripper in such a way as to shift the gripper along a guide, on which are arranged opening means and closing means for the gripper which are suitable for making the gripper go from a closed position in which it clamps the film to an open position in which it releases the film, and vice versa.

Abstract: A platform for pallet wrapping machines includes a fixed base resting on the ground and a turntable which rotates relative to the base and in which a plurality of rollers is integrated, the rollers projecting from it in such a way as to support a pallet and provided with a movement device integrated with them, in such a way that the platform has a total thickness not greater than 10 centimeters.

Abstract: A pallet wrapping platform comprises a lower frame, a pallet supporting table, constraining means interposed between the frame and the table, being designed to allow the frame and table to move by rotating relative to one another, a driving unit and transmission means for transmitting the motion from the driving unit to the table. The table comprises an upper flat disk and at least one lower ring gear, fixed to the disk and designed to interact with the motion transmission means, in such a way that the total thickness of the platform is less than at least 24 millimeters.

Abstract: A wrapping machine (1) comprises a rotating table (2) for supporting products (14); an upright (3) with a perimeter wall (4) in which there is a longitudinal opening (5); a dispenser unit (6) for a wrapping film (15); and a supporting and connecting structure (7) for the dispenser unit (6), connecting it to the upright (3), comprising a carriage (8) and a plate (9). The carriage (8) can be translatably guided by the upright (3). The plate (9), lying in a vertical plane (10), passes through the upright (3) perimeter wall (4) at the opening (5), and connects the carriage (8) to the dispenser unit (6), so that they can translate together along the upright (3). The structure (7) comprises a vertical bar (11) contained in the upright (3) and translating supporting means (29) which connect the plate (9) to the bar (11) and comprise at least one sleeve (13) coaxially coupled with the bar (11) and at, least able to translate guided on the bar (11).

Abstract: A device for cutting and fixing plastic film in machines for wrapping pallets comprises: means for spacing (1) at least one layer (2a) of the film (2) at a distance from the rest of the wrapping already applied to the pallet (13) so as to create an empty compartment (16) between said layer (2a) and the pallet (13); means for deforming (4; 17) said layer (2a) of film (2), able to render possible the access to the compartment (16); means for cutting (3) the film (2); means for withholding (8) the film (2) in the proximity of at least one end (7) of the cut film (2); and means for pushing (6) the end (7) of the cut film (2) within the compartment (16). A sequential process enables activation of the aforesaid device so as to perform the corresponding operations in series.
