Move the cardboard early, until its lateral edge reaches the position of the 诖 phase I. Since the error is not deducted, the position 1248415 applied by the cam is not changed, and it is irrelevant to the recorded error. 庶0 庶冰冰如田,Jδ己Record the edge of the cardboard, -, 彖%, and stop the carrier only early. The middle δ 刖 刖 stopper is not solid 疋 and is shackled to the cylinder. U.S. Patent No. 4 9 8 9 8 5 5 i+,, +, , ^ , , , 855 唬 He describes a positioning device in which the stoppers are mechanically pushed to change the field - and the waters of the waters position. The device consists of a calibration of the cardboard on the board to be used only. A device that compares it with a reference position and adjusts the positions of the stops to calibrate the position. Such a device works like a normal device, and the Wei side has the same danger. In European Patent No. 699,274, a calibration device is known in which the paperboard to be calibrated is actuated by means of a clamping device or a lining that is clamped between them. Then move sideways against the side guides. The side slide guide stops the movement of the cardboard, and the pull rod ends its sliding movement relative to the flat member. This is more suitable for relatively hard cardboard (such as corrugated board). European Patent No. 1,044,908 describes a positioning device for a hot shouting pad, which includes a movable frame with a temporary fastening device of π 扒 , , , , , , , , , , The longitudinal movement is carried out by moving back and forth, and the other direction can be corrected by three vertical short columns (each vertical short column is fixed to the carrier), the center carrier slides into a longitudinal guide, and two The lateral carrier slides into the lateral guide. The three linear motors controlled by the Guanglei-Tian Youyi 5 recording device produced the corrective movement of the shelf. > Müller corrects during the transport of the cardboard by the movable frame 'so that the leading edge of the cardboard in the holder of the holder bar is in the reference position' and thus the temporary fastening of the shelf 1248415 The device releases the cardboard and the shelf can be returned to its original position to resume operation of a new cardboard. This device saves the time required to calibrate the board, thus greatly increasing the productivity of the machine. A very related device is disclosed in the European Patent No. 1, 155,833, wherein the cardboard holding device is coupled to the movable frame by at least one link mechanism, the at least one link mechanism comprising a plurality of levers forming a parallelogram. The parallelogram is stretched about a horizontal axis of rotation to prevent the horizontal force component from being reached by the opening lever of the temporary fastening of the edge of a cardboard on the shelf. Both of the above devices are very efficient and accurate in positioning while the rate at which the cardboard is positioned can be increased. The choice of effective positioning of the cardboard being transported saves the time required for normal calibration. However, the resulting increase in productivity requires a large investment. The cost increase between a conventional calibration system and an uninterrupted positioning device as described in European Patent No. 1,044,908 and European Patent No. 1,151,833 is only practically satisfactory for certain types of machines. And economically reasonable. Finally, a lateral edge device for recording a paperboard at an entry station is described in European Patent No. 1,308,406. According to the apparatus of the invention, the position of the recorded lateral edge of the paperboard is compared to the desired position and a correction signal is generated which produces an adjustment signal sent to an adjustment member for moving the lateral edge to The location you want. Thus, the transported cardboard can be operated directly from the measured spacing between the recorded position and the desired position. On the other hand, this document does not relate to how to implement 1248415. [Invention] It is an object of the present invention to at least partially eliminate the common drawbacks of conventional paperboard calibration devices without causing a significant increase in the cost of the processing machine associated with the paperboard positioning device. . For this purpose, the invention is primarily concerned with a paperboard positioning device for positioning a paperboard into an introduction station of a processing machine as in the first member of the patent application. The main advantage of the non-butter is that in combination with the two calibration methods, in order to calibrate the leading edge of the cardboard, the device uses the cardboard as the conventional positioning device, by means of which the front end positioning device is transported, because the positioning of the cardboard front It is sinful, simple, and has no significant shortcomings. The front end positioning device can be fixed or adjustable. For lateral calibration, use - by 'light
