The cloth rolling machine is the machinery for rolling the fabrics, clothes, and textiles. It is consisted with lots of parts, and each part has its own special function. In order to guarantee the effective rolling, the textiles must be exerted with pressure to increase the friction between rolling and guiding bar and textiles, overcome the tension of textiles, thus pull the textile rapidly, to achieve the stabilization of weft density. To obtain the necessary friction, the cloth guiding bar must be exerted pressure, making the angle that the textiles surround the rolling bar large as much as possible. Now I will give you an introduction of the pressure increasing device.
1. Gravity pressured device
The cloth guiding bar can slide up and down in the locating slot, the pressure that guiding bar push on rolling bar comes from the weight of guiding bar and the acting force the textile against the rolling bar, so the tension of textile is larger, the pressure between the guiding bar and rolling bar is bigger. Using this method, the pressure is average in the direction of the breadth, with the feature of simple layout. When the tension is very small, then there may be a phenomenon that the textile can be held tight, so add another guiding bar to solve this problem.
2. Spring pressured device
Using spring to push the guiding bar to rolling bar, increase the pressure between them. In order to ensure the good function of cloth hold, the guiding bar should have high rigidity, to avoid the lack of hold force that cased by the elasticity deformation of guiding bar.
