Kraft paper valve pocket for cement packaging

When we buy the valve bag from the valve bag manufacturer, we will ask for its flatness, so how can we make it more flat? To solve this problem, not only the quality of the raw materials is required, but it is also very important during production. For example, the speeds of the three machines, such as the weft collector, the speed governor and the wire drawing machine, must be synchronized, so as to ensure the balance of the four-shuttle weft. It will touch the warp thread. At the same time, it is necessary to improve the force distance motor gear and the number of teeth of the force distance motor gear, so as to balance the components, such as tensioning the winding shaft to be stable. More importantly, improve the straightness of the spring of the jumper of the circular loom, so that its elasticity is increased, so that the pressure in the direction of the cam and the four-comb is stable, there will be no twisting phenomenon, and the appearance of the valve pocket will be much smoother.
