New High Viscosity Technology with Co-Rotating Extruders

4 New High Viscosity Technology with Co-Rotating Extruders 

Soon after the patents cited above were issued, publications about the new types of corotating extruders and their applications began to appear in increasing numbers. The secondary literature also cites further publications [24 to 35] from the period between 1951 and 1974, many of which were authored by the licensors Bayer, i.e., predominantly R. Erdmenger and the licensee Werner und Pfleiderer, i.e., H. Herrmann. These publications increasingly pushed process engineering and the various uses of the co-rotating extruder.
