Abstract

UN DISPOSITIVO PARA REGULAR LA TENSION DE LOS HILOS DE LA TRAMA Y RECUPERARLOS EN LOS TELARES QUE COMPRENDE UNA PALANCA OSCILANTE (1) PROVISTA DE UNA GUIA DE HILOS (4) EN EL EXTREMO DE LA CUAL, EN LA POSICION DE REPOSO DE LA PALANCA, SE INTERPONE ENTRE DOS GUIAS DE HILOS FIJAS (11). DE ACUERDO CON LA INVENCION, LOS GOLPES DE DICHA PALANCA SE CONTROLAN MEDIANTE UN MOTOR ELECTRICO LINEAL (3), QUE FUNCIONA BAJO EL CONTROL DE UN SISTEMA ELECTRONICO ASOCIADO AL SISTEMA ELECTRONICO (9, 10) QUE CONTROLA EL TELAR Y A UN SENSOR (8) QUE DETECTA CONSTANTEMENTE LA POSICION DE DICHA PALANCA.A DEVICE TO REGULATE THE TENSION OF THE THREADS OF THE PLOT AND RECOVER THEM IN THE LOOMS THAT INCLUDES A SWING LEVER (1) PROVIDED WITH A GUIDE OF THREADS (4) AT THE END OF WHICH, IN THE POSITION OF THE LEVER, STANDS BETWEEN TWO FIXED WIRE GUIDES (11). IN ACCORDANCE WITH THE INVENTION, THE BLOWS OF SUCH LEVER ARE CONTROLLED BY A LINEAR ELECTRIC MOTOR (3), WHICH OPERATES UNDER THE CONTROL OF AN ELECTRONIC SYSTEM ASSOCIATED WITH THE ELECTRONIC SYSTEM (9, 10) THAT CONTROLS THE LOOM AND A SENSOR (8) WHICH CONSTANTLY DETECTS THE POSITION OF SUCH LEVER.
