Abstract (en)
A roving frame (1) of a spinning line, comprises a drawing device (12), a winding device (14) and a system for detecting breakages of the roving (20) comprising a plurality of detection sensors, a processing device (50) associated with each sensor according to a low-pass or timer filter, and a control device (70) connected to the processing devices (50) to stop the drawing device (12) and the winding device (14) in the presence of a breakage of the roving.
