US Patent 11479009 Slit sheet tensioning device
Article
An expansion device includes an unexpanded slit sheet roll that is wound on a paper core that is longer than the width of the slit sheet paper roll. The paper core is placed onto a rod member. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the rod member. As the paper is pulled, the downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.
