Abstract (en)

[origin: WO8400567A1] Method and device for the detection of an end breakage by detecting a fiber floating and moving in the pneumatic main duct of a fine spinning frame. The output of a photocell (18) detecting scattered light via a fiber crossing an optical beam formed at a predetermined position in a pneumatic main duct (2) is converted into a voltage pulse, which is then amplified, and only voltage pulses higher than a predetermined value are produced, and are integrated over a predetermined period of time. When the integrated value exceeds a set value, it is regarded to be the occurrence of an end breakage, and an identification signal is generated.
