ABSTRACT:
A ribbon blender for a development station of an electrographic copier/duplicator is formed using a plurality of flat blanks stamped from a strip of sheet material. Each blank has three substantially concentric rings joined by two spaced strips. The outer ring and the middle ring are cut to form ribbon segments and then the segments are bent out of the plane of the blank. A plurality of the resulting bent blanks are assembled on a shaft alternately with spacers to form a ribbon blender. The free ends of the ribbon segments of adjacent blanks are in substantially end-to-end alignment to joints form ribbons.
