Davis-Standard Offers Turret Unwind Upgrades

PAWCATUCK, CT | The Davis-Standard aftermarket group offers turret unwind upgrades said to significantly improve productivity and minimize downtime. Company says an upgrade for Green Bay Packaging involved the modification of two turret unwinds on a 1,200-fpm (365 mpm) pressure-sensitive adhesives (PSA) coating line. Davis-Standard changed the turret unwind operation from air brakes with a speeder motor to a fully regenerative operation, reportedly improving both efficiency and performance signifcantly.

“Upgrades are an excellent way to extend the longevity of turret unwinds that are still operational,” says Andre Icso, VP 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 up and running quickly.”

Icso says there are several different upgrades available, but the one for Green Bay was very straightforward. Davis-Standard’s team removed the brakes and speeder belt and installed new turret motors and mechanical power transmission to the unwinding spindles. New slip rings, spindle glue line sensors, and turret position encoders were also included as well as the installation and integration of four new unwinding spindle drives.

Company’s aftermarket group is able to upgrade PLC, drive, and mechanical systems on thousands of existing installations, including those for other brands.
