Abstract
A tufting machine control system for controlling the tension applied to a backing material as it enters the tufting zone of the tufting machine, including a pair of driven backing feed rolls for feeding the backing material. The drive motors for the backing feed rolls are monitored by the control system and are adjusted to control the amount of tension applied to the backing material as it enters the tufting zone of the tufting machine.
