An unwind station for supplying web materials from a roll at constant tension to a work station such as a press. The unwind station has a shaft with an arbor for receiving the web roll. A belt extends around a pulley on the shaft and a brake member which is mounted on one end of a pivotal beam. A biasing force is applied to the opposite end of the beam by a cylinder. The brake serves as a "dancer" to maintain constant tension. The arbor is provided with side-lay adjustment to align the web.
