Precautions when using the air jet reed

(1) The structural form of the special-shaped reed is consistent with the design of the weft insertion system of the loom. Under normal circumstances, air-jet reeds on different air-jet looms should not be used interchangeably to avoid fabric defects and damage to the reed. (2) Before using a new steel reed, check the reed size, structure, firmness, reed blade elasticity, reed tooth uniformity, reed surface flatness and cleanliness, as well as the verticality of the reed blade and reed beam, and the height of the airflow groove. and depth dimensions. If possible, check whether the airflow value meets the requirements. (3) After the steel reed is removed from the machine, the slurry and scale should be cleaned in time, and then the condition of each part should be checked, and the reed should be trimmed according to the requirements of the air-jet reed. The trimmed reed should be properly placed. (4) The reed taken out from the reed repair room or the reed outsourced for repair must meet the quality requirements, and any problems should be corrected in time. (5) When inserting the reed, you should grasp the forward and reverse directions to avoid threading errors. The machinery and tools for inserting the reed should be suitable. The thickness of the reed tool should be suitable for the gap between the reed blades. Generally, the No. 120 reed is used for 100/50.8cm, the No. 100 reed is used for 60 to 100 teeth/50.8cm, and the No. 80 reed is used for 60 teeth/50.8cm or less. The operation must be skillful and meet the requirements. Beginners generally do not wear high-density air reeds. (6) Stop reeding. According to the reeding method required by the fabric technology design, find and break the warp yarns with the same reed teeth and lift them. Use a special tool to insert the upper end of the special-shaped reed, straight out and straight in, and do not slide the reed. Be light. (7) The insertion reed tool should be within the 35mm range above and below the air jet reed to avoid entering, so as to prevent the steel reed teeth from breaking or becoming soft, resulting in a reed path. See Figure 8-3. (8) Air-jet reeds cannot be heavily pressed or stacked, and the air flow grooves on the reed surface must not touch each other to avoid damaging the reed teeth. (9) The position of the side brace should be appropriate to avoid damaging the reed surface. (10) The temperature and humidity in the workshop should be appropriate and ventilated frequently to adjust the temperature and humidity and eliminate fly lint and sizing. The temperature and humidity are related to the type of yarn, sizing, and the dryness of the sizing yarn. The temperature should be controlled between 25 and 28°C. During the period, the humidity of cotton yarn is 73% to 78%, and the polyester-cotton blended chemical fiber fabric yarn is 65% to 70%. (11) Fixing of steel reed: When weaving on the weaving shaft, a torque wrench must be used to tighten the air-jet reed. Use a 5N m (0.51kg m) torque wrench to tighten the screws one by one from the middle to both sides. Check the position of the entrance to avoid hitting the left side of the reed to avoid bending the teeth. (12) The position and amount of movement of the cloth fell in the reed groove ① It is better for the cloth fell to be above the center of the reed groove, and the gap from the upper edge should not be less than 0.3~0.5mm when beating up. ②The width of the air jet reed grooves is mainly 5.5mm and 6mm. Therefore, the fabric mouth cannot jump up and down greatly. If the fabric mouth jumps out of this area, the cloth surface will be easily damaged by high and low peaks and the reed teeth will be damaged.
