On the loom, according to the requirements of fabric organization, the warp yarn is separated up and down to form the motion of shed, which is called opening for short.
The mechanism that completes the opening action is called the opening mechanism. The function of the opening mechanism: separate the warp yarn up and down to form a shed;
According to the requirements of fabric organization, the lifting order of warp yarn is controlled. Dobby opening mechanism - weaving complex small pattern fabrics. Generally, 16 page heald frame is used, up to 32 page heald frame.
Corrugated plate: it stores the information of the lifting sequence of the heald frame, and is generally prepared in advance under the machine according to the requirements of the corrugated plate drawing.
Reading device: converts the information of the corrugated plate into the action of controlling the lifting.
Heald lifting and heald returning devices: implement heald lifting and heald returning actions respectively.
Therefore, a dobby loom with a dobby opening mechanism is called a dobby loom.
