Abstract

UN METODO PARA RETIRAR AUTOMATICAMENTE UNA TRAMA DEFECTUOSA DE LA CALADA EN TELARES DE AIRE. EN EL CASO DE UNA TRAMA DEFECTUOSA, SE EVITA EL CORTE DEL HILO (2) Y SE ALIMENTA SIMULTANEAMENTE UNA DOBLE TRAMA EN LA CALADA (3). EL BUCLE (7) ASI FORMADO ES TRANSPORTADO A LA SALIDA DE LA CALADA (3) MEDIANTE UN CHORRO DE AIRE, DENTRO DE UN DISPOSITIVO NEUMOMECANICO (10) COLOCADO A LA SALIDA DEL TELAR. DICHO DISPOSITIVO (10) CONSTA DE UN CONDUCTO INTERIOR (13) EN EL QUE SOPLA EL CHORRO DE AIRE QUE TRANSPORTA EL HILO DE TRAMA DEFECTUOSO, UNOS MIEMBROS DE AGARRE Y ESTIRAMIENTO INTERMITENTE DEL HILO (15) COLOCADOS CORRIENTE ABAJO DE Y A TRAVES DE DICHO CONDUCTO (13) Y DISPOSITIVOS (19, 21) PARA PROTEGER CONTRA LA SUCIEDAD EL SENSOR OPTICO DE DETECCION DEL HILO (18).A METHOD FOR AUTOMATICALLY WITHDRAWING A DEFECTIVE FRAME FROM THE STREET IN AIR LOOMS. IN THE CASE OF A DEFECTIVE PLOT, THREAD CUTTING (2) IS AVOIDED AND A DOUBLE PLOT IS SUPPLIED SIMULTANEOUSLY IN THE CALADA (3). THE LOOP (7) SO FORMED IS TRANSPORTED TO THE EXIT OF THE CALADA (3) THROUGH A JET OF AIR, INSIDE A PNEUMOMECHANICAL DEVICE (10) POSITIONED AT THE EXIT OF THE LOOM. SUCH DEVICE (10) CONSISTS OF AN INTERIOR DUCT (13) IN WHICH THE AIR JET IS TRANSPORTED, WHICH TRANSPORTS THE DEFECTIVE SCREEN THREAD, SOME MEMBERS OF GRIP AND INTERMITTENT STRETCHING OF THE THREAD (15) PLACED CURRENT DOWN THROUGH THROUGH THE (13) AND DEVICES (19, 21) TO PROTECT THE OPTICAL THREAD DETECTION SENSOR AGAINST DIRT (18).
