Abstract: A film tensioning and steering system can be configured to extract a film from a film source. One or more film characteristics can require that the film tensioning and steering system be isolated from the film source so that a film tension can be maintained within the film tensioning and steering system. A first drive roller pair and a second drive roller pair can be configured to secure the film and enable a dampening roller to maintain the film tension between the first drive roller pair and the second drive roller pair. Additionally, the dampening roller can store an amount of the film as a film buffer. Accordingly, the film tensioning and steering system can maintain the film tension such that a steering system can align the film before the first drive roller pair provides the film at a proper alignment to a downstream system.
