Individual zone tension control
A system for controlling tension on textile material used in forming a preform is disclosed herein. The system includes a sensor and a controller, where the controller is configured to: receive a signal, from the sensor, indicative of a compressive force applied by the textile material feeding into the system; determine whether the compressive force is within range of a setpoint of the tension for the textile material; and responsive to the compressive force being outside the range, send a command of at least one of an increase or a decrease of the tension on the textile material.

a digital-to-analog converter; and
a signal amplifier, wherein the signal is a digital signal, wherein the digital-to-analog converter converts the digital signal to an analog signal, and wherein signal amplifier amplifies the analog signal prior to being received by the controller.
10. A method for controlling tension on textile material used in forming a product, comprising:
receiving, by a controller, a signal from a sensor indicative of a compressive force applied by the textile material feeding into a forming machine;
determining, by the controller, whether the compressive force is within range of a setpoint of a tension for the textile material; and
responsive to the compressive force being outside the range, sending, by the controller, a command of at least one of an increase or a decrease of the tension on the textile material,
