Abstract (en)

[origin: EP0250793A2] A ribbon blender (32) has a shaft (34), and a plurality of blender sections (40, 42, 44) are positioned on the shaft and rotate with it. Three types of modular ribbon blender sections are used in forming the blender, including a center section (44) and first and second end sections (40, 42) assembled on opposite sides of the center section. The end sections are substantially the mirror image of each other. Each of the sections have a hub portion (46, 60, 72) and first ribbon segments (54, 68, 80) and second ribbon segments (56, 70, 82) located in generally helical paths that are spaced from the hub portion. The sections are assembled on the shaft so that the ribbon segments of one section form a continuation of segments of an adjacent section, thus forming substantially continuous helical ribbons around the shaft. The ribbon segments (80, 82) of the center section join an outer ribbon segment of one of the end sections with an inner ribbon segment of the other ribbon section to provide for cross mixing of material in the area of the center section of the ribbon blender. Such a ribbon blender is especially useful for mixing developer material in the sump of an electrographic apparatus, such as a copier/duplicator.
