    Sheet feed to a printing machine 5 is controlled by monitoring a sheet fed to a registration line 3 of the machine and evaluating the monitoring signals at two different evaluating times per machine cycle. On detection of a correct sheet at the first evaluating time, evaluation at the second evaluating time is withheld and the sheet is released to enter the printing press. If, however, a skewed sheet is detected at the first evaluating time the sheet conveying is interrupted for one cycle and evaluation at the second evaluating time is withheld. Thereafter, on detection of a correct sheet at the first evaluating time of the succeeding cycle, evaluation at second evaluating time is withheld and the sheet is released to enter the machine, or on detection of a skewed sheet at the first evaluating time of the succeeding cycle the sheet conveying is stopped. If no sheet is detected at the first evaluating time, evaluation is carried out at the second evaluating time and, on detection of a correct or skewed sheet, the sheet conveying is interrupted for one cycle and evaluation is carried out at the first evaluating time of the succeeding cycle. If a skewed or lacking sheet is detected in any subsequent cycle, any such sheet is prevented from entering the machine and sheet conveying is stopped. <IMAGE>

    The device works as follows.
    Using the tool 9 and the block 12, the feeding of the sheets begins and the sheet 11 is fed through the patch table 2 to the register stops 10 and the paper overlay line.
    In the area of register stops, the sheets are monitored using sensors 4. The latter detect missing (no sheet), early, late, skewed sheets, as well as sheets of good quality.
    The signals of the sensors 4 are evaluated at two different measurement time points (Fig. 3).
    When you turn on the switch On. the feeder 45 includes the first 42 and second 47 trigger control stages of the feeder 12, the magnet 54 is disconnected from the voltage for commissioning the self-feeder.
    Trigger cascades 22, 28 and 55 are not yet included. Node 17 prepares the measuring cycles (fig.Z).
    Get different modes of operation.
    In mode I (proper entry of the first sheet), the feeling heads 4 establish a quality sheet, the trigger stages 22 turn on, the indicator lamps 24 go out. Through circuit AND 27 of node 6, the trigger cascade 28 is turned on. Through scheme AND 29, magnet 31 is removed from under voltage, i.e. the entry of the sheet into the printing press is unlocked.
    In mode II (the first sheet in the first measurement cycle (Fig. 3) is a skewed sheet) one of the triggers is turned on. Through the output circuit of AND 25 and the circuit of AND 59, the trigger stage 55 is turned on, and the pulse shaper 61 is started, with the result that the magnet 54 is excited for a short time. Because of this, the feeder stops for one working cycle. Thus, no double sheets can occur on the loser.
    Now, at the first measuring cycle of the next working cycle, the sheet position is re-measured.
    In mode III (the sheet has been corrected during this time), the first measuring stroke of the second working cycle of the machine is measured. The output of the circuit OR 23 conducts the signal. Trigger cascade 28 is switched on via circuit AND 27. Trigger cascade 55 is recalled through circuit IL 56, and circuit 29 off circuit 29, i.e. unlocking the entry of the sheet in the printing machine.
    When the trigger stage 28 is turned on, the second measurement cycle (Fig. 3) is blocked through AND circuit 64 for further measurement.
    In the 1U mode (the sheet was not corrected, i.e. there is still a skewed sheet), the measurement is performed at the first measuring step of the second working cycle. Included trigger stage 55 produces through circuit AND 48 and circuit OR 49 the return of trigger stage 47, and thus the final shutdown of the feeder.
    In V mode, at the first measurement cycle, the missing sheet is set.
    The measurement is carried out at the second measurement. Regardless of which sheet is in the second measurement cycle — qualitative or skewed — through the OR 60 circuit, the AND 58 circuit and the OR 57 circuit, the trigger stage 55 is turned on and the pulse shaper 61 is started.
    Thus, to prevent double sheets, the feeder is turned off for one working cycle. A new measurement is made at the first measuring cycle of the next working cycle. Depending on the measurement result (qualitative or skewed sheet), the further process proceeds similarly.
    In the y mode (passage of the sheet), the first sheet is processed according to mode I, i.e. the trigger cascades 22 are turned on and the magnet 31 is removed from under voltage, with the result that the sheet is unlocked in the printing press. At the same time, the second measuring cycle is blocked, i.e. Only the first measurement cycle is supplied to block 14.
    91
    During the passage of sheets (a series of sheets after the first sheet), a skewed or defective sheet is received at the first measuring step. In this case, the trigger cascade 28 returns to its original position, the node 6 is blocked, i.e. the sheet cannot enter the printing press.
    In order to avoid double sheets, when the trigger stage 28 is turned on, pulse generator 33 generates a pulse, which returns the trigger stages 42 and 47 to the initial position and, thus, turns off the feeder.
    Due to the preloading of sheets, the machine goes into the state of the minimum number of revolutions
    The pulse shaper 33 pulses also includes a trigger stage 34, resulting in an indicator
    2580010
    The lamp 38 illuminates and signals that the machine is not yet completely disconnected.
    If the machine is driven to the number of 5 revolutions, which ensures the re-commissioning of the feeder, then the first driver 39 drives the puller through the first circuit 37 and thus, the feeder is put into operation again.
    ten
    At the first measuring cycle of the next working cycle, a new measurement of the position of the sheet is made.
    Depending on the measurement result, the signal is further processed in the same way as the IIL and IV modes.
    The use of the invention improves the efficiency of the device.
