Blown film is main target for technology billed as an option to smooth bore feedthroats in extrusion.

A new type of grooved-feed section has shown promise in solving a wide range of film extrusion problems while at the same  time adding stability to the overall process and making more judicious use of energy.

light groovesCalled Light Groove Feed (LGF) technology and developed by Gloucester Engineering Corp., Gloucester, Mass., it is promoted as an option to smooth-bore extruders. Gloucester has roughly 100 of them in the field, mostly at blown film processors. The technology has been applied to cast film and foam extrusion lines as well. LGF has been retrofitted to existing extruders in sizes from 30 to 150 mm. It requires no change to screw design or drive size. The technology is not intended to replace the intensively grooved feed sections common for processing HMW-HDPE film…
