Zusammenfassung:	A dunnaging apparatus and method for controlling web tension are provided. The apparatus includes a frame that is configured to support at least one supply of a web of paper having a continuous length and a width. A paper forming device is configured to receive the web of paper in a substantially flat configuration and fold the web along at least one line extending generally along the length of the web to form a paper cushion of reduced width. At least one roller is rotatably mounted on the frame and configured to support the web of paper between the supply and the forming device. The roller is formed at least partially of foam so that an outer surface of the roller is elastically deformable and the roller is configured to provide a nonuniform cross-sectional shape across the width of the web according to variations in the tension in the web across the width of the web.
