Abstract: A web path for conveying a web material includes at least two support rollers contacting a single major surface of the web material, wherein the web material is of indefinite length and has a first and a second edge. A first support roller contacts a first edge region of the web material, and a second support roller contacts a second edge region of the web material such that the web material has a substantial un-contacted region between the first and the second support roller including at least about 50% of the width of the web material. At least one of the first support roller and the second support roller are supported on a bowed shaft such that at least one of the first and second support rollers is angled with respect to the direction of motion of the web.
