Hosokawa Alpine American said its AutoTherm is an automatic gauging system that uses computer-controlled, segmented cartridge heaters at the die lip to improve gauge control and film flatness, eliminating wrinkles and improving film appearance.
A sensor, either contact or noncontact, measures gauge variation around the circumference of the bubble, then processes the data through Alpine's software. A segmented heating ring for the die lip has independently controlled heater cartridges, which add heat to thick spots and reduce heat in thin spots.
AutoTherm operates with all Alpine dies, including monolayer and up to eight-layer dies for packaging film, said the company in Natick, Mass.
