Davis-Standard LLC's aftermarket group did a turret unwind upgrade for Green Bay Packaging Inc.
Davis-Standard modified two turret unwinds on a pressure sensitive adhesives line running 1,200 feet per minute. The company in Pawcatuck, Conn., changed the turret unwind operation from air brakes with a speeder motor to a fully regenerative operation, significantly improving efficiency and performance.
Davis-Standard installed new turret motors and mechanical power transmission to the unwinding spindles. The work also included new slip rings, spindle glue line sensors and turret position encoders—as well as installing and integrating four new unwinding spindle drives.
“Upgrades are an excellent way to extend the longevity of turret unwinds that are still operational,” Said Andre Icso, vice president of global aftermarket sales. “It also allows them to run lighter products with significantly better tension control, less scrap and increased energy savings. For this upgrade, the modification and re-commissioning took only two weeks, enabling us to get the customer back and running quickly.”
