Abstract

SE EXPONE UN PROCESO PARA LA FABRICACION DE UN TEJIDO DE REFUERZO DE ARTICULOS HECHOS CON CAUCHO, TALES COMO NEUMATICOS, CORREAS TRANSPORTADORAS, TUBOS FLEXIBLES, MANGUERAS Y SIMILARES, QUE COMPRENDEN UNA SERIE DE CORDONES METALICOS (1) ORIENTADOS PARALELAMENTE ENTRE SI EN UNA SOLA DIRECCION, Y EN EL QUE CADA CORDON COMPRENDE HILOS METALICOS (4) ENROLLADOS EN ESPIRAL EN RELACION MUTUA, CARACTERIZADO PORQUE AL MENOS UNO (3) DE LOS ALAMBRES DEL CORDON CONSISTE EN UN MATERIAL CON MEMORIA EN CUANTO A LA FORMA. DURANTE LA FASE DE INCORPORACION DE LOS CORDONES (1) AL MATERIAL ELASTOMERICO, EL HILO (3) CON MEMORIA EN CUANTO A LA FORMA TIENDE A RECUPERAR LA FORMA MEMORIZADA INICIALMENTE Y, A TRAVES DE LA FUERZA GENERADA DURANTE ESTA RECUPERACION, TRANSMITE POR FRICCION A LOS ALAMBRES CIRCUNDANTES (4) FUERZAS QUE TIENDEN A ACORTAR EL PASO DEL CORDON (1) SIN SEPARAR CADA ALAMBRE (4) DEL SIGUIENTE, DANDO COMO RESULTADO UNA BUENA PENETRACION DE MATERIAL ELASTOMERICO ENTRE LOS ALAMBRES (4). EL CIERRE DEL CORDON (1) SE MANTIENE EN LOS CICLOS SIGUIENTES DE CALENTAMIENTO, GRACIAS A LAS CARACTERISTICAS DE DEGRADACION DE LA MEMORIA IMPARTIDAS AL ALAMBRE. LA INVENCION ES PARTICULARMENTE APROPIADA PARA TEJIDOS QUE FORMAN CAPAS DE CORREAS TRANSPORTADORAS Y PARA LOS PLIEGUES DE LA ENVOLTURA DE NEUMATICOS.
