The function of the air jet reed and the conditions it should meet
1. The role of air-jet reed in the weaving process 1. The function of arranging warp yarns is to arrange the warp yarns to the correct position in a certain order and density, ensuring that the warp yarns are interlaced with the weft yarns according to the fabric structure during the weaving process, and the fabric reaches the specified effective width. 2. The function of air guide and weft insertion is to guide the air flow and control the diffusion of the air flow, so that the weft yarn can be smoothly introduced into the shed and guide the weft yarn to fly correctly. Keep the weft yarn in the notch to achieve stable weft insertion. 3. The function of beating up is to make the weft yarn introduced into the shed evenly and orderly beat towards the cloth fell to form a fabric. 2. Conditions that air-jet reed should meet in the weaving process (1) The structure, shape and specifications meet the requirements. (2) The shape, angle and thickness of the reed teeth meet the requirements. (3) The dimensions are accurate, and the height and depth of the airflow groove are accurate. (4) The reed surface is flat, the reed teeth are evenly arranged, and the reed number is accurate. (5) The reed teeth are smooth and consistent, have good elasticity, have high hardness and wear resistance, the reed body is tough, straight, and has strong earthquake resistance. (6) The reed teeth are vertical to the bottom and front of the aluminum reed beam. (7) The air flow groove is precise, making the air flow stable, the air consumption is low, and the air pressure value and air pressure waveform line meet the requirements. (8) The reed edges, etc. meet the requirements.
