Abstract
Dispositivo abrecartas, que se caracteriza por el hecho de estar constituído por un soporte alargado, el cual está dotado superiormente de una guía longitudinal acanalada que lo ocupa de extremo a extremo, y en la cual es susceptible de desplazarse el borde de apertura de la carta, a ambos lados de cuya guía se encuentran dos rodillos giratorios locos, uno de ellos provisto de una cuchilla circular que se aplica contra el otro, la cual determina el corte del canto aludido a medida de que se desplaza entre los rodillos.
