Abstract

CONSISTE EN UN ALIMENTADOR DE HOJAS QUE PUEDE MONTARSE SOBRE UNA MAQUINA DE ECRIBIR O SOBRE UNA IMPRESORA. LAS HOJAS (12) QUE SE COLOCAN EN UN ALIMENTADOR (28) SE HACEN PASAR A UN RODILLO (210) MEDIANTE RODILLOS DE FRICCION (250). DESPUES DE LA OPERACION DE IMPRESION, LAS HOJAS SE PASAN SOBRE UNA MESA DE ALMACENAMIENTO (150) POSICIONADA ENFRENTE DEL ALIMENTADOR. LOS RODILLOS DE FRICCION ESTAN CONECTADOS PERMANENTEMENTE AL RODILLO DE LA MAQUINA DE ESCRIBIR POR MEDIO DE UNA TRANSMISION MECANICA (212,218,226,245,248) Y GIRAN EN LA MISMA DIRECCION QUE EL RODILLO DE LA MAQUINA DE ESCRIBIR. LOS RODILLOS DE FRICCION (250) ESTAN MONTADOS SOBRE UN BRAZO OSCILANTE (252) PARA SER ACERCADOS O ALEJADOS SELECTIVAMENTE DE LA PRIMERA HOJA QUE VA A SER INTRODUCIDA, POR MEDIO DE UNA PRIMERA LEVA (254). DESPUES DE QUE UNA HOJA HAYA SIDO RECIENTEMENTE INTRODUCIDA, UNA SEGUNDA LEVA (242), TAMBIEN ACOPLADA AL RODILLO DE LA MAQUINA DE ESCRIBIR, TIENE QUE SER LLEVADA A UNA POSICION DE REFERENCIA MEDIANTE UN GIRO DEL RODILLO DE LA MAQUINA DE ESCRIBIR SUFICIENTE PARA EXPELER LA HOJA CORRIENTE. EL RODILLO GIRA ENTONCES EN DIRECCION INVERSA, MEDIANTE LA ACCION DE UNA SEGUNDA LEVA EJERCIDA A UNA PALANCA (262), MEDIANTE LA CUAL SE CIERRA UN EMBRAGUE (260). DURANTE LA SUBSECUENTE ROTACION DEL RODILLO DE LA MAQUINA DE ESCRIBIR EN DIRECCION HACIA DELANTE, EL EMBRAGUE HACE GIRAR LA PRIMERA LEVA (254) UNA REVOLUCION, PARA ENGANCHAR LOS RODILLOSDE FRICCION (250) CON LA PARTE SUPERIOR DE LA HOJA (12), EFECTUANDO ASI LA ALIMENTACION DE UNA NUEVA HOJA. EN EL FINAL DEL MOVIMIENTO DE GIRO A TRAVES DE UNA REVOLUCION DE LA LEVA, LOS RODILLOS DE FRICCION SE SEPARAN DE LAS HOJAS Y EL EMBRAGUE SE ABRE, HACIENDO QUE LAS LEVAS SE INDEPENDICEN DE LOS SUBSECUENTES MOVIMIENTOS DE ROTACION DEL RODILLO EN UNA U OTRA DIRECCION.
