BLADE SET FOR HAIR CUTTING APPLIANCE AND METHOD FOR ITS MANUFACTURE

摘要

A stationary blade (10) for a blade set (4) of an electrically operated hair cutting appliance (1), including a first wall (20) and a second wall (30), each wall defining a first surface (22a, 32a), a second surface (22b, 32b) facing away from the first surface, and a laterally extending leading edge (23, 33) defining a plurality of laterally spaced apart longitudinally extending projections (24, 34), wherein the first surfaces of the first and second walls face each other, at least at their leading edges (23, 33), while facing projections along the leading edges of the first and second walls are mutually connected at their tips (26, 36) to define a plurality of generally U-shaped teeth (12), and the first surfaces of the first and second walls define a laterally extending guide slot (16) for a movable blade (40) of said blade set between them.

1. A stationary blade for a blade set of an electrically operated hair cutting appliance, including a first wall and a second wall, each wall defining a first surface, a second surface facing away from the first surface, and a laterally extending leading edge a plurality of laterally spaced apart longitudinally extending projections, wherein the first surfaces of the first and second walls face each other, at least at their leading edges, while facing projections along the leading edges of the first and second walls are mutually connected at their tips to define a plurality of generally U-shaped teeth, and the first surfaces of the first and second walls define a laterally extending guide slot for a movable blade of said blade set between them,
wherein the projections of the first wall have an average thickness that is less than an average thickness of the projections of the second wall.
