Title: Innovations of William R Hardesty
Introduction
William R Hardesty is a notable inventor based in Richmond, VA (US). He has made significant contributions to the field of electrical perforation technology, holding 2 patents that showcase his innovative approach to enhancing web perforation processes.
Latest Patents
His latest patents include an "Apparatus for electrical perforation of webs" and a "Method of electrically perforating a planar web." Both inventions focus on the technique of electrically perforating a web at 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 and gas flow are carefully selected to enable the striking of multiple arcs per half-cycle. This innovation allows for a reduction in spacing between adjacent perforations in the web. Additionally, the patents disclose a perforation practice involving the preselection of cigarette filter tipping paper based on its chemical composition. 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.
