Abstract
EN UNA MAQUINA DE IMPRIMIR ROTATIVA, CON UN CILINDRO DE FORMA (1) Y UN CONTRACILINDRO (2), P.EJ. UNA PRENSA, POR EL QUE DISCURRE ENTRE LOS MISMOS UNA PLATINA DE IMPRESION (3), SE CONSIGUE UNA CALIDAD DE IMPRESION ABSOLUTA SOBRE EL ANCHO TOTAL, INCLUSO TAMBIEN EN UNA PLATINA EXTREMADAMENTE ANCHA Y EL CORRESPONDIENTE CILINDRO DE FORMA DELGADO (1), DEBIDO A QUE EL CILINDRO DE FORMA (1) SE HA DOTADO CON UN SOPORTE FIJO (4) Y UNA ENVOLTURA (8) QUE GIRA ALREDEDOR DE ESTE, A TRAVES DE UNOS ELEMENTOS DE SOPORTE (11) APOYADOS POR UN EFECTO DE PRESION CONTROLADO INDIVIDUALMENTE O POR GRUPOS. COMO CONSECUENCIA DE ELLO, SE CONSIGUE UN PERFIL DE IMPRESION UNIFORME SOBRE EL ANCHO DE LA PLATINA DE IMPRESION, Y AL MISMO TIEMPO UNA CONSIDERABLE HENDIDURA DE IMPRESION PLANA. SE EVITAN DEFORMACIONES Y DESPLAZAMIENTOS DE LA ENVOLTURA DEL CILINDRO DE FORMA (8), TRANSVERSALES RESPECTO AL PLANO DE IMPRESION (D), PORQUE SE HAN PREVISTO ELEMENTOS DE APOYO TRANSVERSALES (16) ADICIONALES, PARA EJERCER UN EFECTO DE FUERZA DE RETROCESO TRANSVERSAL, RESPECTO AL PLANO DE IMPRESION (D) SOBRE LA ENVOLTURA DEL CILINDRO DE FORMA (8). MEDIANTE SENSORES DE POSICIONAMIENTO (39, 40) O SENSORES DE APOYO (35), SE REGULA EL EFECTO DE LA FUERZA DE RETROCESO DE LOS ELEMENTOS DE APOYO TRANSVERSALES (36), DE TAL MODO, QUE LA POSICION DE LA ENVOLTURA DEL CILINDRO DE FORMA (8), SE MANTIENE INCLUSO TAMBIEN EN CILINDROS DE FORMA ESPECIALMENTE ANCHOS Y DELGADOS. VIBRACIONES DEL CILINDRO DE FORMA, SE EVITAN POR MEDIO DE ELEMENTOS DE APOYO HIDROSTATICOS (11, 16) CON EFECTO AMORTIGUADOR.
