Abstract
CABEZA IMPRESORA MATRICIAL QUE INCLUYE UN GRUPO DE DISPOSITIVOS DE IMPRESION POR PUNTOS (30) QUE FUNCIONA DE FORMA SELECTIVA PARA QUE SUS RESPECTIVAS PARTES DEFINIDORAS DE PUNTOS (4) ENTREN EN CONTACTO CON EL MEDIO A IMPRIMIR Y LOS PUNTOS QUEDEN IMPRESOS EN EL MISMO, CADA UNO DE DICHOS DISPOSITIVOS CONSTA DE UN ELEMENTO LAMINAR FLEXIBLE (11), FIJADO POR UN EXTREMO DEL MISMO A UNA ESTRUCTURA DE SOPORTE (1) DE LA CABEZA Y QUE TIENE EN SU OTRO EXTREMO LA PARTE DEFINIDORA DE PUNTOS (4) DEL DISPOSITIVO. CADA DISPOSITIVO CONSTA ASIMISMO DE UN ACTUADOR CONTROLABLE ELECTRICAMENTE (3) QUE FUNCIONA PARA IMPONER MOVIMIENTO AL ELEMENTO FLEXIBLE (11) EN UNA POSICION DE ACTIVACION (A) PERPENDICULAR EN RELACION AL PLANO PRINCIPAL DE DICHO ELEMENTO PARA PROVOCAR DICHO CONTACTO DE LA PARTE DEFINIDORA DE PUNTOS (4) DEL DISPOSITIVO, SIENDO LA DISTANCIA DE DICHA POSICION DE ACTIVACION (A), DESDE UN EXTREMO DEL ELEMENTO FLEXIBLE DEL DISPOSITIVO, PEQUEÑA EN COMPARACION CON LA DISTANCIA DE LA POSICION DE ACTIVACION DE LA PARTE DEFINIDORA DE PUNTOS DEL DISPOSITIVO. ESTA ZONA DEL ELEMENTO FLEXIBLE (11) QUE ESTA ENTRE DICHO EXTREMO Y LA POSICION DE ACTIVACION (A), TIENE LA FORMA DE AL MENOS UN TRIANGULO TRUNCADO. LA CABEZA DE IMPRESION HACE POSIBLE QUE SE LLEVEN A CABO OPERACIONES DE IMPRESION A ALTA VELOCIDAD, OBTENIENDOSE UN RECORRIDO DE IMPRESION SATISFACTORIO SIN PROVOCAR ESFUERZOS EXCESIVOS EN LOS COMPONENTES.
