Abstract
Description
technical field
[0001] The invention relates to a tension control device, which is used to control the tension of fabrics such as elastic or non-elastic fibers and yarns during the unwinding process. Background technique
[0002] Tension control devices mainly include mechanical tension controllers, electronic tension controllers, and magnetic flux tension controllers. For example, the Chinese patent CN2251566Y announced on April 9, 1997 discloses an electronic tension controller, which detects pressure changes in real time through a tension detection device and feeds back to the electrical control system to finally keep the tension within a set range. Tension control devices are needed in many occasions in the chemical fiber weaving industry. For example, in the production process of elastic webbing, after the elastic warp is unrolled, the tension must be controlled within the set range through the tension control device, so as to ensure the tension of the entire elastic we...
