Abstract
The present invention refers to an apparatus and a method for wrapping a film around an object. The apparatus includes a device capable of being electrostatically charged and capable of transmitting the electrostatic charge to the portion of film that comes out of the carriage. In this way, the fixing of the leading end flap of the film around the object to be wrapped is thus facilitated. In fact, the leading end flap of the film, as soon as it is dispensed, remains stretched out of the carriage and, as soon as it meets the object to be wrapped, it immediately fastens to it due to the attraction force. The rotation is then activated to wrap the film around the object. The apparatus is simple to make, cheap, and highly efficient.
Claims10
Apparatus (10) for wrapping a film (6) around an object (4), wherein said apparatus (10) comprises
- a) a carriage (1) adapted to house a reel of said film (6),
- b) an opening (11) in said carriage (1) to allow said film (6) to exit the carriage (1),
- c) a motorized roller (7) adapted to facilitate said exit of the film (6) from the carriage (1) through said opening (11);
- and
- d) a device (19) placed inside the carriage (1) at said opening (11) along the path traveled by the film (6) exiting the carriage (1) and adapted to be electrostatically charged and transmit said charge to the leading end portion of film (6) exiting said carriage (1) to fix the leading end portion of film (6) to the object (4) to be wrapped.
