Abstract

EN UNA ROTATIVA ALIMENTADA CON HOJAS DE DOBLE IMPRESION, HAY UNOS CILINDROS COLOCADOS DE MODO QUE LA DISTANCIA DESDE UNA POSICION DE IMPRESION, A SABER, UN PUNTO DE CONTACTO ENTRE UN CILINDRO DE IMPRESION (4A,B) Y UN CILINDRO DE MANTILLA (5A,B) HASTA UNA POSICION DE CAMBIO DE SUJECION SOBRE EL SIGUIENTE CILINDRO DE IMPRESION O UN CILINDRO DE TRANSPORTE (13) SEA MAYOR QUE EL LARGO DE UNA HOJA Y QUE UNA VEZ LIBERADA LA HOJA DE ENTRE EL CILINDRO DE MANTILLA (5A,B) Y EL CILINDRO DE IMPRESION (4A,B) DE UNA UNIDAD DE IMPRESION PRECEDENTE, LA HOJA SEA TRANSFERIDA ENTRE LOS CILINDROS DE IMPRESION (4A,B) Y ENTRE EL CILINDRO DE IMPRESION (4B) Y EL CILINDRO DE TRANSPORTE (12), CON LO QUE SE EVITAN LAS INCORRECCIONES DE IMPRESION RESULTANTES DE UNA TRANSFERENCIA IMPERFECTA DE LAS HOJAS PARA REDUCIR EL NUMERO DE HOJAS DESPERDICIADAS.IN A ROTARY POWERED WITH DOUBLE PRINTED SHEETS, THERE ARE SOME CYLINDERS PLACED SO THAT THE DISTANCE FROM AN IMPRESSION POSITION, KNOWLEDGE, A CONTACT POINT BETWEEN A PRINT CYLINDER (4A, B) AND A CYLINDER OF MANTILLA (5 B) UP TO A POSITION OF EXCHANGE CHANGE ON THE FOLLOWING PRINT CYLINDER OR A TRANSPORTATION CYLINDER (13) BE GREATER THAN THE LENGTH OF A SHEET AND THAT ONCE THE SHEET BETWEEN THE MANTILLA CYLINDER (5A, B) AND THE PRINT CYLINDER (4A, B) OF A PRINTED PRINTING UNIT, THE SHEET IS TRANSFERRED BETWEEN THE PRINT CYLINDERS (4A, B) AND BETWEEN THE PRINT CYLINDER (4B) AND THE TRANSPORT CYLINDER (12), WITH THAT THE IMPRESSION INCORRECTIONS RESULTING FROM AN IMPERFECT TRANSFER OF THE SHEETS TO REDUCE THE NUMBER OF WASTEED SHEETS ARE AVOIDED.
