Abstract: A simple operation winds film around, and thereby wraps therewith, a loadable object over its entire (six) surfaces. Film is wound spirally around the loadable object by revolving film feeders along a circular path about a horizontal axis while advancing the object through the circular path and along a path of the horizontal axis in one direction. After the loadable object is so spirally wrapped, it is rotated in a horizontal or vertical plane by an angle of 90 degrees. The loadable object is then advanced in the reverse direction again through the circular path while the film feeders are revolved as before to cause another film from the film feeders to be wound spirally around the loadable object. One film feeder may furnish a continuous strip of film, and another film feeder may furnish a continuous string of film formed by compression of such a strip of film.
