The new Toggle FastGap from flat-die maker Extrusion Dies Industries LLC means processors no longer will have to shut down lines to clean and lubricate EDI's FastGap system.
FastGap changes die gap by applying force at regular intervals along the die's lower lip, to bend the lip.
In standard FastGap equipment, the gap-changing mechanism consists of a stationary bar and a moving bar, with sets of male and female keys set at an angle, so the keys slide against each other during gap adjustment. That metal-on-metal contact is what made lubrication necessary, said John Ulcej, executive vice president of engineering and technology.
“To eliminate lubrication, we've replaced the old mechanism with an array of toggles along the width of the die. Instead of the sliding motion of the keys, there is the rotary motion of the pins and bushings at the end of the toggle shafts,” Ulcej said.
EDI is in Chippewa Falls, Wis.
