摘要：The device is intended for the detection of a thread during the detection of theends of threads (21) in suction pipe (17) crossflown by air, comprising a sensor device (22)having a transmitter (31) and a receiver (32) in a textile machine that produces cross-wound bobbins. A measuring field (26) is formed between the transmitter (31) and thereceiver (32). The suction pipe has a curvature in the area of the measuring field (26). Themeasuring field (26) is arranged in the proximity of the smaller radius of the suction pipe(17), which has a recess (27) oriented in the running direction of the suction pipe (17) inorder to form the measuring field (26). The suction pipe (17) is curved upstream anddownstream of the measuring field (26) in such a way that the detected thread is tensedinside the recess (27) in such a manner that it is spaced at least partly from the bottom ofthe recess (27) in the measuring field (26), thereby making it possible to easily andreliably detect the thread.
