Abstract
A printing apparatus, method, and computer program of designing a floating roller in a tensioning system adapted to one of supply and receive a web of material to or from one of a web supply and a processing machine, comprising inputting external radius of said floating roller, measure of elasticity of the material, a thickness of the material, width of the material, and angles at which the material contacts the floating roller; and adjusting mass of the floating roller and rotational inertia of the floating roller based on external radius of the floating roller, measure of elasticity of the material, thickness of the material, width of the material, and angles at which the material contacts the floating roller such that the floating roller maintains a constant tension on the web of material as the material is passing through the tensioning system.
