Abstract

Device for detecting thread breaks in throstle frames.The device includes a head that holds a sensitive piezoelectric sensor that is guided in an alternative manner along the throstle frame the sensor establishes contact during its movement over each of the threads or filaments with which the throstle frame works said head is moved by a traction system made of cables that also act as electricity conductors said head holds elements that are sensitive to a magnetic field for the optical indication of the position of the head, which also has optical indicators that are activated by the piezoelectric sensor signal the piezoelectric head is connected to a control cabinet that can produce the activation of a light indicator that corresponds to each of the lengthwise sections into which the control machine has been divided.< IMAGE >The device is for the detection of breakages in threads (7) in a continuous spinning machine and comprises a head carrying a piezo-electric sensor (1) guided alternatively along the machine, establishing contact with each thread or filament with which the machine is working. The head is moved by a cable traction system, the cables also being conductors of electricity. The head also incorporates components sensitive to a magnetic field for optical indication of its position. The head also has optical indicators activated by the sensor signal. It is connected to a control cabinet (25) capable of illuminating luminous indicators (19-24) corresponding to each of the sections into which the machine is divided longitudinally.
