Abstract
An apparatus for maintaining uniform tension across a width of a web includes a roller, a first arm and a second arm, a plurality of devices, and a plurality of links. The roller includes a shaft, about which the roller rotates, that defines an axis of rotation. The first arm and the second arm are coupled to opposite sides of the shaft of the roller and to a corresponding one of the plurality of devices such that each device is allowed two degrees of rotational freedom about the arm to which it is coupled. Each of the devices is pivotably coupled to a corresponding one of the plurality of links such that the roller is allowed to pivot about a first axis. Each link is pivotably coupled to a stationary frame such that the roller is allowed to pivot about a second axis.
