Abstract (en)
[origin: DE19525260A1] An optoelectronic sensor (S) for detecting a weft yarn passing through a scanning zone (3) has at least one light source (L, L'), at least one photoelectric receiver (R1, R2) that is sensitive to variations in light intensity and is connected to an evaluation circuit (C), and a slitted diaphragm (A1, A2) arranged between the yarn and the receiver. In a weft yarn measurement and feeding equipment (F), the sensor (S) detects overend unwinding of the thread from the feeding body (B). At least two receivers (R1, R2) arranged next to each other are oriented towards the scanning zone and their receiving surfaces (4, 5) are covered by a slitted diaphragm (A1, A2), with the exception of a limited area. The slitted diaphragms (A1, A2) are arranged at an acute angle of maximum 90 DEG in relation to each other.
