Abstract:
An apparatus for fabricating bichromal elements comprising:a) a separator member having a central rotating point comprising first and second spaced apart, opposed surfaces with an edge region in contact with both of said opposed surfaces, wherein 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, wherein each surface has a substantially annular cup for receiving a hardenable liquid spaced apart from and at least partially surrounding the central rotating point, the annular cup being of sufficient size to allow for substantially evenly spreading of a received hardenable liquid in the annular cup prior to the hardenable liquid spreading out of the annular cup b) nozzle apparatus for dispensing first and second differently colored hardenable liquids in the cups of the first and second surfaces, respectively, c) means for substantially uniformly spreading the liquid material in each of the annular cups located in the first and second surfaces, d) means for substantially uniformly spreading the liquid material from the cups over the first and second surfaces toward said edge region to form a reservoir containing side by side portions of the first and second liquid materials outboard of said edge region, and for forming ligaments from said reservoir.
