Abstract
A device for monitoring and regulating the tension in the sliver produced by a carding unit and transferred from this along a path to a unit for its collection into cans for further processing, comprising a deviator bar pivoted on a pivot and an oppositely located rod provided with an element which opposes the rotary movement of the bar deriving from the variations in tension of the sliver deviated by it, the sliver tension being measured by sensors on the basis of the effect induced by the sliver on the bar, the relative signals being transmitted to the control unit which compares the values received with the allowable limiting values and implements the consequent interventions.
