Film wrapping using a single roll
Abstract:
This invention is to register printed film on product while wrapping the printed film from a single roll. This is achieved by using a sensor that can read a mark on the film in order to insure that a predetermined length of film is pulled off the roll and the printed portion of the film is in registration with the product. The marks on the film establish the amount of film needed to wrap the product. A sensor such as a photo sensor reads the mark and determines whether the proper length of the film has been pulled off the roll. When the amount of film pulled of the roll does not coincided with sensor reading, the distance between where the product stops and the sealing bar is varied. This allows the length of the film to be adjusted until the sensor readings and the length of the film coincides.
