ABSTRACT:
An improved apparatus for handling a moving material of indeterminate length utilizes a pair of endless elements located on opposite sides of an intended path of travel for the moving material. Each element is configured to engage and hold a corresponding edge of the material at least partially through the apparatus. The apparatus includes a detector assembly adjacent the path of travel for detecting deviation of at least one edge of the moving material from a normal operating path and outputting signals to initiate corrective reaction to the deviation. The reaction is defined in a predetermined relationship to time the edge remains out of its normal operating path. The apparatus also includes an adjustment device in operative communication with at least one frame member and the detector assembly. The adjustment device receives the corrective signals and positionally adjusts the corresponding frame member in response thereto to achieve the normal operating path. The apparatus may be configured to adjust the frame member at an emergency reaction upon gross deviation of the edge from the normal operating path.
