The hair warp tension buffer device 3 is transversely arranged between the support pendulum shaft 205 and the tension pendulum shaft 113, and two ends of the hair warp tension buffer device are respectively and fixedly connected with the two wall plates 4.

As can be seen from fig. 2 or fig. 4, the position of the cushion sleeve 303 is closer to the front of the loom, so that the wrap angle of the pile warp can be increased, and the tension cushion effect can be improved.

As can be seen from fig. 2, the warp yarns run from the warp beam, first through the support rocker 205, through the buffer sleeve 303 to the tension rocker 113, and then through the rocker 115 to the front of the loom. The supporting pendulum shaft 205 plays a role in guiding and positioning the hair warps, the buffer sleeve 303 is closer to the front of the loom, the hair warps form a larger wrap angle on the buffer sleeve 303, and meanwhile, the wrap angle of the warp yarns on the tension pendulum shaft 113 is also increased, so that the accurate control on tension induction and the improvement of the buffering effect are both facilitated. The swing rod 115 is positioned right below the tension swing shaft 113, so that the following of the warp and the cloth can be conveniently realized, and a satisfactory effect is achieved. The multi-connecting-rod structure rigidly connected with the cloth-moving main motion realizes the active synchronous following of the hair warp. When the terry cloth fell of the towel loom moves backwards, the hair warp also actively follows the backward movement, thereby ensuring higher tension at the end of the terry cloth, and realizing higher quality of the terry cloth. When the terry cloth fell of the towel loom moves forward, the pile warp also actively moves forward along with the terry warp, the tension of the pile warp is kept unchanged, and the phenomenon that the pile warp is raised to cause the picking is avoided.

The cloth moves the active following device and the tension active control device composite structure of the hair warp, realize the perfect combination of high-speed following and tension active control, can see from the figure that the cloth moves the active following device and exerts the direction of force to the tension pendulum shaft 113, mean to the left side tension rocker arm 203 center, it is very small to the moment of torsion that the tension rocker arm 203 produces, can ignore the cloth and move the active following device and control the tension active control of the hair warp. That is to say, the tension control of the warp is relatively stable and is not influenced when the loom runs at high speed and actively follows the motion. On the other hand, in the tension control device, when the tension rocker arm 203 swings back and forth when the control tension is changed, the second link 110 in the up-down direction is not greatly affected by the forward and backward swing of the swing axis driving arm 112.

The new cloth motion warp loom warp tension control mode formed by the cloth motion positive following device, the warp tension active control device and the warp tension buffer device is the most ideal tension control structure at present, and can provide the best warp tension in the weaving process of the towel loom and weave perfect looped piles and forged piles at high speed and high efficiency.
