ABSTRACT:
A device for continuously regulating the feeler sensitivity in the control of weft insertion in a loom. The device includes a selector having a memory into which the sensitivity value corresponding to the count of the weft passing through the eye of each rod is fed. The selector is electrically connected to a piezoelectric sensor-comparator, and is controlled by a logic control unit. The logic control unit provides electrical pulses or signals for selecting weft presenter rods of a presenter, and the same signal from the logic control unit is provided to the selector, such that the selector utilizes the signal from the logic control unit for providing the feeler sensitivity information to the sensor-comparator.
