Device for regulating feeler sensitivity in control of loom weft insertion

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. UN DISPOSITIVO PARA REGULAR EN CONTINUO LA SENSIBILIDAD DEL PALPADOR EN EL CONTROL DE INSERCION DE TRAMA EN UN TELAR, COMPRENDIENDO UN SELECTOR PROVISTO DE UNA MEMORIA EN LA QUE PARA CADA BARRA PRESENTADORA DE TRAMA SE INTRODUCE EL VALOR DE SENSIBILIDAD CORRESPONDIENTE AL NUMERO DE LA TRAMA QUE PASA POR EL OJO DE DICHA BARRA, ESTANDO DICHO SELECTOR CONECTADO ELECTRICAMENTE A DICHO SENSOR-COMPARADOR PIEZOELECTRICO Y SIENDO CONTROLADO POR LA UNIDAD LOGICA DE GOBIERNO CON LOS MISMOS IMPULSOS ELECTRICOS QUE LOS EMPLEADOS PARA SELECCIONAR DICHAS BARRAS DE DICHO PRESENTADOR. LA INVENCION ENCUENTRA APLICACION EN LA INDUSTRIA TEXTIL, PARTICULARMENTE EN LA FABRICACION DE TELARES.
