Yarn Feeder Parts

In order to achieve the desired effect in many production processes of spinning—such as inserting weft yarn into a high-efficiency loom like today's shuttleless loom, or feeding a set of yarns onto a warping machine, or in other processes—the yarn traction method often causes great changes in yarn tension. A particular example is on a shuttleless loom, where the loom bearing weft yarn is introduced at very high and highly variable speeds, creating a peak tension inside the yarn that leads to yarn breakage.

We know of several machines that control the yarn brake based on yarn tension, so that it can be maintained at a high level without abrupt changes. This equipment is equipped with a brake that mechanically responds to the tension in the yarn, thereby reducing the tension the brake applies to the yarn, and vice versa. By adjusting the yarn tension value, automatic control of the brake can be achieved.

This kind of machine equipment usually has a slow response time when detecting tension changes; however, the reason for this defect in the custom textile machine 3-yarn clip is that when yarn tension changes, the yarn tension is detected by a mechanical component that moves easily and is then regulated by the yarn. Although the weight of this mechanical component is small, it still has inertia and elasticity; therefore, under sharp changes in yarn tension, they can dynamically interact with the yarn, achieving conversion between kinetic and elastic energy. This dynamic change slows the response and also reduces the braking control effect of these devices, while also affecting the yarn tension.

In addition, due to the dynamic interaction between machine components and yarn, an unstable influence is exerted on the existing yarn state, especially under rapid tension changes, where the dynamic interaction between yarn and machine components persists continuously. These double yarn clip devices with higher wholesale prices, besides responding slowly to tension changes, also cannot remain completely passive when detecting yarn; they always change their tension to some extent, thereby affecting the brake adjustment effect. Moreover, this instrument cannot measure the absolute yarn tension value, and can only monitor the relative change in yarn tension to achieve control of the yarn brake.
