Per identification mark sensor 24 let a photoelectric detector, the senses changes in reflected light caused by the tag 12a. A light source 76, photodiode 78, an amplifier 80, and a pulse shaper 82 as shown in FIG. 6 produce a very tight output pulses to match a detector circles 42 and through the OR gate 40 to the display 34, this signal is the leading edge of the identification tag again.

The compliance detector stage 42 receives four input signals - (1st) leading gate, (2nd) knife pulse, (3,) trailing pulse and (4 ·) identification mark pulse. In addition to these signals, the correspondence detector stage 42 has push-button and WHhI switches to enable the operator to set either manual or automatic operation and, if necessary, to enable the operator to manually increase or decrease the speed of the measurer. This stage 42 generates four output _{signals T} which are fed to a correction speed and direction stage 44 - (1st) automatic, (2) increase of the knife speed, (3) reduction of the knife speed and (4) over-time pulse.

In addition to the input signals mentioned, stage 44 receives signals All further signals are the 5 ^ 0 pulses per knife revolution from the Angle encoder 28 * As will be explained in more detail below, a binary UP / DOWN SHIer, a storage register, a hat eirervi elf acher and a binary counter are used in step 44 to generate a variable pulse frequency output signal for to generate the correction rotor 30. The input signal from the angle encoder 28 is the frequency generator for this stage 44.

Two output signals from this stage are fed to the motor tranelator stage 46 - C1 «) forward pulse and (2nd) reverse pulse pulse. Since the correction rotor 30 is a stepper motor, the motor translator Ί6 converts the input signals into the appropriate sequence and power so that they can be transferred to the stepper motor 30.

FIG. K shows the start pulse detector stage 36 with the angle encoder 28 together with a diagram of the binKr-coded decimal setting switch, with the characters "x" increasing for the specified switch position. When the angle encoder 28 is driven by the knife or cutting knife 18, a pulse sequence of 5® ^Q Ißipuisen per knife run is fed to the binary coded decimal counter 50 via a single input IJKD gate kB. These Irspulae cause the counters 50 to count starting from zero. The counter outputs © are serially connected to the binary coded Deaimaleinstelizälilers 5% with diodes 52.

The combined undelayed input signal and delayed input signal from the pulse shaper II8 to the NOR gate 122 results in an interval of 20 microseconds during which one of the inputs is a logic "1", the output of the NOR gate 122 also holds logic "O" while the counter is "cleared" and "preset". The AND gate 126 receives an input signal from the ¹¹ O "output of the multivibrator 130 and the"! "output of the multivibrator 132 when these two Input signals are logic "1", then the "1" output of the pulse shaper Il8 is passed through the one input of the NOR gate 134, whereby an output signal is generated which toggles the multivibrator 130. The AND gate 128 receives an input signal from the output of the multivibrator 130 "nd from ¹¹ O" output of the multivibrator 132. When these two A · gange signals logical "1", then the "1" output of the pulse shaper IL8 by the AND gate 128 and NOR gate 134 passed through to tilt multivibrator 130.

If the maximum count has not been reached, the AND gate 146 enables the signal to increase the knife speed to be applied to the OR gate 150, which in turn drives the converter 152, the OR gate 154 and the OR gate 156. OR gate 154 and AND gate 158 form an AND-OR multivibrator which is "set" to a logical "!" Output, which enables the counter 111 to count up and the output of the converter l ^ O sets to "0" when the first pulse to increase the knife speed occurs * The "1" to "0" transition of the knife speed pulse can go through the OR gate 156 as a result of the output signal "0" of the converter 160 to the AND gate 162 are normally "1", the output signal of the OR gate 156 can pass through the AND gate to advance the counter 111.

This process continues until the Kesseracluiitt occurs in accordance with the marker pulse or the up / down counter 111 a maximum count A maximum count of 255 is sampled by the NAND gate 168 (Fig. 9B), producing an "O" output when all inputs are "1". The logical "O" output of the NOT -AND-Tores 168 blocks gates 146 and 170 (Fig. 9 A), which prevents any pulses from passing through the OR gate 150, so that further up counting to the ZShIer is prevented.

Up to now, the control influence of the correction speed and direction stage according to FIGS. 9A and 9B has been shown during a conformance state, as well as a non-conformance state which requires an increase in the knife speed. In the following, a non-conformance condition is assumed which requires a reduction in the knife speed. This occurs when the repetition lengths begin to become longer, altogether in the state of agreement. Regarding coincidence states, it is assumed that the counter 111 contains a count and the correction motor 30 is "forward". If the identification mark pulse occurs during the pulse of the tracking torea, the over one tlaioninge detector stage 42 according to FIG. 6 generates an pulse or reduction in the knife speed. This pulse is applied to the AND gates 172 and 170 and, since the direction "forward.""is, only conducts the AND gate 172, whereby the pulse eur reduction of the knife speed is generated at the output of the OR gate 174. If the output of the OR gate 174 ^{goes to logic" I 1} *, the output goes signal of the converter * 176 to logic "0" · Since the counter 111 still contains a number, the output signal of the NOR gate · s 122 will go to ¹¹ O ", whereby the AND gate 178 is disabledι also the output signal of the converter 180 should be "1", so that it is possible that the NAND gate 182 goes to "0". This "0" output of the NAND gate 182 causes a "reset * 'of the AND-OR multiribrator (154-158) to an" O "output signal in the counting direction of the counter, causing the counter 111 to count down «When is this first pulse reduced the massear speed

Basically enabled the effect of the control is that the correction motor is raised to a maximum speed in one direction or decreased to zero speed as in the reverse direction to a maximum speed? is brought depending on the requirements of the maintenance register.

When the device is switched to manual operation (FIG. 6), the measure raising and knife reduction pulses from the correspondence detector stage k2 according to FIG. 6 are signals input by hand. The "automatic" signal of the stage according to FIG. 9 A is a logic ¹¹ O ", which sets the output signal of the NOT" AND gate ·· Il6 to logic ¹¹ I ", so that the counter 111 is cleared or preset during manual operation will. If timing pulses occur, they pass through the NAND gate 11%, clear the memory register 112 and read the contents of the up / down counter 111 into this register. This keeps the contents of the memory register close to the value of counter 111 when a manual match is obtained and prevents control from being switched from manual match to automatic mode.
