回路を示している。(Example) Next, the present invention will be explained in more detail with reference to Examples. The attached figure shows the basic circuit of a device implementing the method according to the invention.
この回路は、発光送信器２と光電受信器３との間の光線

。受信器３によって受信されるパルスは、本質的に、送
信器２から送出されるパルスに相応し、すなわち、これ
は狭幅パルスである。The circuit is based on the fact that the light beam 1 between the luminescent transmitter 2 and the photoelectric receiver 3 is free of filamentous materials and dirt. The pulse received by the receiver 3 essentially corresponds to the pulse emitted by the transmitter 2, ie it is a narrow pulse.
このパルスは、送信器２と受信器３との間の妨害作用の
ない空間に信号を送るのに充分なものとする。このパル
スを出力パルスと呼称する。This pulse is sufficient to transmit the signal into the undisturbed space between the transmitter 2 and the receiver 3. This pulse is called an output pulse.

ルス幅および時間特性が変化するため、送出されたパル
スと特性の異なる信号が受信器３に達する。If a filamentous material enters the area of ray 1, this ray is weakened and, as it passes through the optical path between transmitter 2 and receiver 3, the interpulse spacing, pulse width, of ray 1 consisting of individual pulses is reduced. Since the time characteristics change, a signal with characteristics different from the transmitted pulses reaches the receiver 3.

信器２に供給される。The method according to the invention is such that the width of the pulses emitted by the transmitter 2 is increased in steps until a pulse with a pulse shape corresponding to the output signal is received at the receiver 3. In that case, a state between transmitter 2 and receiver 3 that corresponds to a predetermined required correction value can be established by corresponding tests. This is true for the feed properties of the filamentous material in the area between the transmitter 2 and the receiver 3 (feed thickness, feed clarity, etc.) or the condition of the filaments or dirt. In general, the thread-like material has thick and thin parts, and this changes depending on the supply speed in the portion of the light beam 1, so that the pulse width changes. Contamination in the area between transmitter 2 and receiver 3 likewise results in the clearly discernible changes mentioned above. The signal formed in the receiver 3 is passed to the microcomputer 6 via common components such as an amplifier 4 and a threshold switch 5.
is supplied to In this microcomputer 6, the received pulses are evaluated by means of a program stored in a programmable read only memory (FROM) 7, and corresponding correction values are formed, which correction values are supplied to the transmitter 2 via an output amplifier 8.

る。If there is some dirt in the area of the light beam, a signal "maximum attenuation" is sent out via the amplifier 9, which signal is used for activation of the operator warning device and for cleaning the thread monitoring area. Signals provided in the form of output signals send out the signals "fault" and "shut down" through amplifier 10. Signals SIO "IN" and SIO "OUT" input and read by components 11 and 12 are used for information exchange with a microcomputer (not shown).
