Abstract

DISPOSITIVO NEUMATICO DE TENSION DEL EXTREMO DE LA TRAMA PARA TELARES NEUMATICOS. UN DISPOSITIVO NEUMATICO DE TENSION DEL EXTREMO DE LA TRAMA PARA TELARES NEUMATICOS PERMITE MANTENER EL EXTREMO LIBRE DE LA TRAMA TENSADO, DESPUES DE QUE HAYA SIDO INSERTADO EN LA CALADA, ASI IMPIDIENDO O PUNTUALMENTE AMORTIGUANDO CUALQUIER OSCILACION LONGITUDINAL ELASTICA DEL HILO DE LA TRAMA. EL DISPOSITIVO NEUMATICO DE TENSION DEL EXTREMO DE LA TRAMA CONSISTE EN UN VENTILADOR (1) INSERTADO ENTRE DOS HOJAS ADYACENTES (6) DE LA URDIMBRE MAS ALLA DE LA ZONA DE ORILLO SEPARADO DE LA TELA SIENDO TEJIDA. LA CORRIENTE DE AIRE PROCEDENTE DEL VENTILADOR (1) DESVIA EL EXTREMO LIBRE DEL HILO DE LA TRAMA ENTRE LAS DOS HOJAS (6) SEPARADAS, DE ESTA FORMA FRENANDO DICHO HILO LO SUFICIENTE PARA IMPEDIR SU OSCILACION ELASTICA DESPUES DE QUE SE HAYA PRODUCIDO SU INSERCION.PNEUMATIC DEVICE OF TENSION OF THE END OF THE FRAME FOR PNEUMATIC LOOMS. A PNEUMATIC FRAME END TENSION DEVICE FOR PNEUMATIC LOOMS ALLOWS THE KEEPING OF THE FREE FRAME OF THE FRAME TENSIONED, AFTER IT HAS BEEN INSERTED BY THE SOUTHERN ORIGINALLY SOUTHERN LOSSIAL. THE PNEUMATIC DEVICE FOR TENSIONING THE END OF THE WEIGHT CONSISTS OF A FAN (1) INSERTED BETWEEN TWO ADJACENT LEAVES (6) OF THE WARM BEYOND THE EDGE AREA SEPARATED FROM THE FABRIC. THE AIR CURRENT FROM THE FAN (1) DEFLECTS THE FREE END OF THE WEFT THREAD BETWEEN THE TWO BLADES (6) SEPARATED, IN THIS WAY BY BRAKING SUCH A THREAD ENOUGH TO PREVENT ITS ELASTIC SWING AFTER IT HAS BEEN PRODUCED.
