Take you to understand the Shuttle Loom

There are many classifications of looms. According to the weaving method, they can be divided into shuttle looms and shuttleless looms. Many friends asked how to adjust the opening time of shuttle looms. Now take you to understand.

The time adjustment of the five major movements of the shuttle loom should follow the following basic principles:

1. The opening time is generally near Shangxin. In addition, the beating-up can be configured in the open period of the shed, so that when the reed is beating-up and retreating, the weft is not easy to reverse back, which is beneficial to tightening the weft.

2. The shuttle time should be set before the lower center, so that the shuttle enters the shed later in the lower center. In addition, this arrangement can ensure that when the shuttle enters the shed, the shuttle is already fully opened or nearly fully opened, which is beneficial for the shuttle to enter the shed. In addition, the shuttle can be made to fly close to the reed, which is conducive to the stability of the shuttle.

3. The shuttle should exit the shed when the shed is closed to a certain extent. If the shuttle is required to exit the shed before the shed starts to close, the time allowed for the shuttle to fly in the shed is short. To make the shuttle pass through the shed on time, the only way to increase the picking force is to increase the picking force. Noise, machine material consumption and power consumption.

4. The coiling time is arranged in the period when the sley swings from back to front. When the sley swings forward, it is at heald level or half-opened shed. The height of the shed is small, and the fabric and warp yarns are relatively loose. At this time, the winding will help stabilize the warp yarn tension and tighten the weft yarn. When the sley retreats and the shed is fully open, the tension between the warp yarn and the fabric is relatively high, and the warp yarn may break when being rolled up.

5. The warp let-off time is arranged in the period when the sley swings from front to back. At this time, the shed is about to fully open and the warp tension is relatively high. Reduce warp yarn breakage.
