Abstract
A device is disclosed for detecting defects in needles on a knitting loom which is operating. The device comprises at least one Hall probe magnetic detector the active surface of which has a width less than the thickness of the needles to be detected. The detector is mounted such that the needles all pass successively in front of it during their working movement, and an electronic circuit transforms the signals received from the magnetic detector into a signal for controlling the stoppage of said loom. The electronic circuit comprises first and second electronic circuits each of which is adapted to supply a signal for controlling the stoppage of the loom.
