A web tension device includes a pressure source and a stationary housing. A translatable unit is translatable into and out of a cavity of the housing and includes an inlet that is connectable to the pressure source. A distal end of the translatable unit includes a tensioning surface with openings to enable outflow of pressurized fluid to apply a pushing force to a web in a roll-to-roll process. Proximal openings enable outflow of the fluid into a gap between the housing and the translatable unit. When tension of the web is reduced, an outward force that is exerted by pressure in the gap pushes the translatable unit outward, pushing the web outward until an inward force that is exerted by the web balances the outward force. When tension of the web increases, the inward force pushes the translatable unit inward until the inward force is balanced by the outward force.
