Latest Patents
Roger L. Hopkins holds a patent for an "Apparatus for electrical perforation of webs." This invention allows for the electrical perforation of a web at a high hole density by applying alternating-current voltage across an electrode pair facing the web. Pressurized gas is supplied to the electrode gap, and the voltage amplitude level, along with gas flow and direction, is selected to enable the striking of multiple arcs per half-cycle. This innovation reduces the spacing between adjacent perforations in the web. Additionally, the patent discloses a perforation practice that involves preselection of cigarette filter tipping paper based on the chemical composition of the paper. The apparatus described includes electrode support members with gas flow conduits formed integrally and a capstan drive unit that is resiliently biased into engagement with a web take-up roll.
