Abstract

DISPOSITIVO NEUMATICO DE SEGURIDAD DE TENSION DE TRAMA PARA GUIAS AEREAS, DEL TIPO EN QUE UN HILO (F) DE TRAMA ES LANZADO POR AIRE INYECTADO EN UN CANAL (5) DE LANZAMIENTO FORMADO EN LA CAÑA (3) DE LA GUIA Y, A LA SALIDA DEL TINGLADO, EL EXTREMO LIBRE DE DICHO HILO ES DESVIADO HACIA LA BOCA DE ENTRADA DE UN CANAL (11) LATERAL DE TENSION DE TRAMA POR UN INYECTOR (12) DE AIRE SUSTANCIALMENTE TRANSVERSAL A LA DIRECCION DE DICHO CANAL (5) DE LANZAMIENTO. EL CANAL (11) LATERAL DE TENSION DE TRAMA TIENE UN CAMINO FORMADO EN ARCO Y CONDUCE DENTRO DE UNA EXTENSION (6) DE CANAL DE DICHO CANAL (5) DE LANZAMIENTO. MEDIOS (13) PARA DETECTAR LA PRESENCIA DE LA TRAMA ESTAN POSICIONADOS EN DICHA EXTENSION (6) DE CANAL, CORRIENTE ABAJO DE LA BOCA DE SALIDA DE DICHO CANAL (11) LATERAL.PNEUMATIC FRAME TENSION SAFETY DEVICE FOR AIR GUIDES, OF THE TYPE IN WHICH A THREAD (F) IS LAUNCHED BY AIR INJECTED IN A LAUNCHING CHANNEL (5) FORMED IN THE GUIDE CANE (3) AND, AT THE DEPARTURE FROM THE TINGLADO, THE FREE END OF SUCH A THREAD IS FORWARDED TO THE ENTRY MOUTH OF A SIDE TENSION CHANNEL (11) BY AN INJECTOR (12) OF SUBSTANTIALLY TRANSVERSAL AIR TO THE DIRECTION OF SUCH CHANNEL (5) OF LAUNCH. THE FRAMEWORK VOLTAGE SIDE CHANNEL (11) HAS A ROAD FORMED IN AN ARC AND LEADS WITHIN A CHANNEL EXTENSION (6) OF SUCH LAUNCH CHANNEL (5). MEANS (13) TO DETECT THE PRESENCE OF THE FRAME ARE POSITIONED IN SUCH CHANNEL EXTENSION (6), CURRENT DOWN FROM THE OUTLET MOUTH OF SUCH CHANNEL (11) SIDE.
