Abstract
A machine for applying tubular film to objects includes a mandrel about which a tubular film is passed, a perforation assembly for forming a perforation line across a width of the tubular film prior to the tubular film moving onto the mandrel, and a sleeve ejection arrangement associated with the mandrel to separate the tubular film along the perforation line to create a tubular sleeve that is ejected off of the mandrel and onto an object. The perforation assembly includes a perforation unit mounted for movement across the width the tubular film, the perforation unit including a perforation blade that is rotated over the tubular film, to apply the perforation line, as the perforation unit moves across the width of the tubular film.
