PURPOSE: An aligning method and an aligner are provided to prevent lowering of efficiency by executing an aligning processing as it is and reducing the number of correction times in the case deviation is comparatively small, and to prevent deterioration of accuracy by interrupting the aligning processing in the case the deviation is large, and then, correcting the deviation, thereafter executing the aligning processing. CONSTITUTION: In the case the deviation is equal to or exceeding a switching value after alignment, but, below an interruption limit value, the positional deviation of each glass dry plate (6 and 7) is corrected after finishing a cycle of normal operations of a long-sized steel plate (1), then, a series of the steel sheet (1) aligning processing is executed within a prescribed time while securing the required accuracy. In the case the deviation is equal to or exceeding the switching value after the alignment and the interruption limit value, the aligning processing is interrupted once, and after correcting the positional deviation of the glass dry plates (6 and 7), the regular processing of the long-sized steel plate (1) is executed, so that the number of the deviation correcting times does not exceed the number of required times, then, the series of the steel plate (1) aligning processing is executed within the prescribed time. |
