Lebanon, OR – May 23, 2017 – ENTEK, a leading producer of twin-screw co-rotating extruders and microporous separators for lead-acid and lithium batteries, has been awarded a U.S. Patent for its Self-Aligning Shafts & Couplings. United States Patent 9,573,313 B2 was awarded to ENTEK on February 21, 2017 for its ‘Extruder Screw Shaft Alignment Apparatus and Method’.
ENTEK employees Craig Benjamin and Melissa Jensen-Morgan, along with Dean Elliott, a former ENTEK employee now with Interfacial Consultants LLC, are credited as the inventors of the concept.
Originally introduced by ENTEK for use on its QC3TM twin-screw extruders in 2015, the self-aligning concept was designed to ensure that the installation of the screw shafts into the couplings was done easily and correctly. Correct alignment is essential to maintaining the correct orientation of the parts in the twin-screw extruder for optimal performance. Prior to this invention, the task was time-consuming and prone to error.
