THE FRAMEWORK IS MOUNTED FOR PIVOTATION SO THAT THE ROTATIONAL AXIS OF THE ROLLER MAY BE EXTENDED PERPENDICULARLY TO THE DIRECTION OF TRAVEL OF THE WEB, OR MAY BE SHIFTED TO EXTEND AT VARIOUS SELECTED ANGLES TO SUCH DIRECTION OF TRAVEL. THE ROLLER IS OF A WIDTH, AS MEASURED ALONG ITS AXIS OF ROTATION, WHICH IS LESS THAN THE WIDTH OF THE WEB AS MEASURED PERPENDICULARLY TO ITS DIRECTION OF TRAVEL. A SUITABLE ACTUATING DEVICE IS PROVIDED FOR PIVOTING THE FRAMEWORK IN RESPONSE TO A SENSED DEPARTURE OF THE WEB FROM A DESIRED COURSE OF TRAVEL.
