Dense road of fabrics are one of the most common defects in fabrics. One of the reasons for the dense road of fabrics is that some weaving machine delivery mechanisms use mechanical let-off devices.
Eliminate thin road measures
1. The electronic let-off device and the elastic back beam control system have good real-time performance, fast response, and automatic adjustment function. The consistency of the tension of each weaving cycle is good, and a simple and effective method is found for eliminating the leaky and dense road.
2. In order to prevent the switch car from being dense, the thin road can be eliminated by programming. In front of the switch car, if you start the stepper motor and turn it down
Turn, the warp tension reaches the standard tension before driving, and the rear loom starts. This effect is to move the welt back to tighten the first weft yarn to prevent the formation of a thin road.
