Differentials, Tension Control

Differentials, Tension Control A differential tension control mechanism is provided to balance the tension difference across the web. The differential tension control can alternatively be implemented on donor take-up and supply rollers. They also prevent the lateral movement of the donor in the nip region. They also improved the quality of print. They tended to generate a lot of movement between the print units.

The tension control differential also works in conjunction with phase shifting and speed-correcting right angle differentials. The tension control system comprises a microprocessor that combines with a dedicated signal processor to provide a simple and reliable method of adjusting and controlling web tension.
