Methods and apparatus for fabricating bichromal elements
Abstract:
An apparatus for fabricating bichromal elements comprising a separator member having a central rotating point, the separator member having first and second spaced apart, opposed surfaces with an edge region in contact with both of said opposed surfaces. The spacing between the opposed surfaces varies with the distance outwardly from the central rotating point such that the spacing is the largest at the central rotating point and the spacing decreases outwards from the central rotating point and the spacing is a minimum at the edge region. Further each of the opposed surfaces has a substantially annular cup spaced apart from and substantially surrounding the central rotating point. The apparatus for fabricating bichromal elements also includes apparatus for dispensing first and second differently colored hardenable liquids in the cups of the first and second surfaces, respectively, and an apparatus for substantially uniformly spreading the liquid material in the annular cups located in the first and second surfaces and for substantially uniformly spreading the liquid material from the cups over the first and second surfaces toward said edge region to form a reservoir of liquid material outboard of said edge region, and for forming ligaments from said reservoir.
