Abstract
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.
