Abstract

UNA IMPRESORA DE IMPACTO (30) QUE COMPRENDE UNA CABEZA DE IMPRESION (31) QUE ATRAVIESA A LO LARGO DE UNA GUIA PARA IMPRIMIR UNA LINEA SOBRE UN DOCUMENTO (32) DE UN GROSOR S, Y QUE ESTA PROVISTA DE MEDIOS DE CONTRASTE PARA SOPORTAR EL DOCUMENTO (32) CONTRA LA CABEZA (31) Y PARA CONTRASTAR LA FUERZA DEL IMPACTO EJERCIDA POR LA ULTIMA CONTRA EL DOCUMENTO. LA CABEZA DE IMPRESION (31) SOPORTA UN RODILLO SEPARADOR (34) QUE HACE QUE LOS MEDIOS DE CONTRASTE CEDAN PARA COMPENSAR EL GROSOR S, QUE VARIA DE ACUERDO CON EL DOCUMENTO (32), Y DE ESTA FORMA MANTENER CONSTANTE LA DISTANCIA D ENTRE LA CABEZA (31) Y EL DOCUMENTO (32). LOS MEDIOS DE CONTRASTE COMPRENDEN UNA PLATINA FLEXIBLE (33) SUJETA DE FORMA QUE PUEDA CEDER EN LOS EXTREMOS, DE LONGITUD AL MENOS IGUAL O MAYOR QUE LA DE LA LINEA DE IMPRESION Y QUE TIENE UN MARCO DE SECCION VARIABLE DE MANERA QUE LA PRESION GENERADA ENTRE LA PLATINA (33) Y EL RODILLO (34) SEA BASICAMENTE CONSTANTE A LO LARGO DE LA LINEA DE IMPRESION.
