Working principle of jacquard machine:

On the jacquard machine, the pattern plate is sleeved on the flower tube, each weft turns over a pattern plate, and the flower tube is pressed against the horizontal needle once. When there are holes on the pattern plate, the head end of the horizontal needle extends into the holes of the pattern plate and the flower tube, so that the hook end of the straight needle is still hung on the lifting knife. When the lifting knife rises, the straight needle rises, and the heald is lifted by the first thread hook and through wire. At this time, the warp thread penetrating into the heald eye is also lifted to form the upper layer of the shed. A heald hammer is hung in the lower heald ring of heald. When the shed is closed, it plays the role of returning heald by its weight. When there is no hole on the pattern plate, the horizontal needle retreats through the convex head to push the corresponding straight needle, so that the hook end of the straight needle is separated from the lifting knife. Therefore, the heald and warp connected with the straight needle are not lifted, and the warp will sink below to form the lower layer of the shed. Therefore, the movement of each warp is determined according to whether there are holes or not on the pattern plate, and the holes on the pattern plate are rolled according to the design requirements of pattern and organization. Therefore, the movement of warp also meets the requirements of pattern and organization.
