20140305272 | Film Perforation Apparatus - An apparatus for creating perforations in wrapping film uses a component that contains a plurality of needle points (or other piercing features) formed along a free-wheeling support bar. The bar is positioned to contact the wrapping film while it is being unrolled and is in a ‘tensioned’ state (in some embodiments, immediately prior to contacting the element to be wrapped). The free-wheeling perforation apparatus contacts a mechanized (driven) film roller such that the exposed needle points rotate against the driven roller and make the perforations in the film as it travels over the film roller. As long as the film roller is formed of a pliable material, the needles will pierce the film and create the desired perforations. The size and placement of needles can be adjusted to provide the required pattern of perforations, as well as dictate the size of the actual perforations. | 10-16-2014 |
20130247729 | Film Perforation Method - A method of creating perforations in wrapping film uses an apparatus that contains a plurality of needle points (or other piercing features) formed along a free-wheeling support bar. The bar is positioned to contact the film while it is being unrolled and is in a ‘tensioned’ state (in some embodiments, immediately prior to contacting the element to be wrapped). In performing the method, the free-wheeling perforation apparatus contacts a mechanized film roller such that the exposed needle points rotate against the mechanized roller and make the perforations in the film as it travels over the film roller. As long as the film roller is formed of a pliable material, the needles will pierce the film and create the desired perforations. The size and placement of needles can be adjusted to provide the required pattern of perforations, as well as dictate the size of the actual perforations. | 09-26-2013 |
20110095077 | Film Perforation Apparatus - A rotating perforation apparatus contains a plurality of needle points (or other piercing features) formed along a free-wheeling support bar, where the bar is positioned to contact the film while it is being unrolled and is in a ‘tensioned’ state (in some embodiments, immediately prior to contacting the element to be wrapped). In particular, the free-wheeling perforation apparatus contacts a mechanized film roller such that the exposed needle points will rotate against the mechanized roller and make the perforations in the film as it travels over the film roller. As long as the film roller is formed of a pliable material, the needles will pierce the film and create the desired perforations. The size and placement of needles can be adjusted to provide the required pattern of perforations, as well as dictate the size of the actual perforations. | 04-28-2011 |
