Abstract

Una hoja (10) para una maquinilla de afeitar que incluye un miembro de hoja generalmente plano (12) que tiene una anchura a lo largo de un eje de anchura, una longitud a lo largo de un eje de longitud transversal y dimensiones menores a lo largo de un eje de grosor que es normal tanto a dicho eje de anchura como a dicho eje de longitud, teniendo dicho miembro de hoja (12) un filo frontal no lineal permanentemente formado que se extiende en general a lo largo de dicho eje de longitud y está definido por una pluralidad de ondas permanentemente forma das (15) que tienen crestas (80) y senos (82) que se curvan suavemente, que se extienden por encima y por debajo de dicho eje de longitud en una dirección que es paralela a dicho eje de grosor, caracterizada porque dicho filo fron tal no lineal está situado en un plano que es paralelo a dicho eje de grosor, teniendo dicho miembro de hoja un límite elástico y estando deformado más allá de dicho límite elástico con una fuerza aplicada para producir dicho filo no lineal y dichas ondas de tal manera que el miembro de hoja tiene una configuración y mantiene dicha configuración en ausencia de dicha fuerza aplicada, con lo que dicha hoja proporciona un ángulo variable tangente a la hoja a lo largo de dicho filoA blade (10) for a razor that includes a generally flat blade member (12) having a width along an axis of width, a length along an axis of transverse length and dimensions smaller than along an axis of thickness that is normal both to said axis of width and to said axis of length, said sheet member (12) having a permanently formed nonlinear front edge extending generally along said axis of length and is defined by a plurality of permanently formed waves (15) having ridges (80) and breasts (82) that curve gently, extending above and below said axis of length in a direction that is parallel to said thickness axis, characterized in that said non-linear front edge is located in a plane that is parallel to said thickness axis, said sheet member having an elastic limit and being deformed beyond said elastic limit with a force applied to produce said non-linear edge and said waves such that the sheet member has a configuration and maintains said configuration in the absence of said applied force, whereby said sheet provides a variable angle tangent to the sheet along said edge
