The first extruder in this country to have the new eight-screw devolatilizing section from Gneuss, Inc., Matthews, N.C., was delivered last September to a processor in Florida. It’s part of a turnkey sheet line from Davis-Standard Corp., Pawcatuck, Conn., built to reprocess undried PET thermoforming regrind back into sheet for thermoformed berry boxes. The vacuum on the eight-screw MRS device is controlled by an in-line viscometer located before the melt pump that feeds the die. The viscometer sends a signal to raise or lower the vacuum to maintain consistent melt viscosity. The 130-mm diam. single-screw extruder is the largest so far with the MRS Multi Rotation Section and the second in the world for sheet. (The first went to Brazil 18 months ago.) Gneuss is now designing a 160-mm MRS, which will be featured, but not exhibited, at the NPE Show in Chicago in June. (704) 841-7251 • www.gneuss.com (860) 599-1010 • www.davis-standard.com
