Variator Replacement Packages

The Variator Replacement package allows customers the ability to upgrade only the Tension Variator portion of a shuttle style machine. On many older machines, the shuttle tension variator creates numerous problems for production personnel. Once worn out these variators become inconsistent and allow film tension to greatly vary during a production run. Inaccurate set-up, and inconsistent tension control cause a large amount of scrap.

This variator replacement package transforms the variator system to an electronic line shaft controlled, servo axis. This servo exactly follows the encoder feedback from the machine. The servo then follows EXACTLY, the speed of the nip rolls. Whether running 20 FPM or 250 FPM, the servo will follow accurately and deliver very consistent film tension.

The operators have the ability to adjust shuttle tension through a data entry keypad unit. A + or - adjustment is available AND limited to a pre-determined limit.

Like other packages CSI offers, this package is available as a customer installed retrofit, if desired.
