The principles and types of electronic edge twisters
1. The edge twisting principle of the electronic edge twister No matter how the electronic edge twister is divided, the edge twisting principle is the same, the only difference lies in the driving method of the edge twister. 1. Threading method of spinning yarn Heddle yarn “G”: This yarn passes through the eyelet on the riding heddle “D” between heddles “A” and “B”; the yarn of skein “H” ends with The needle yarn is threaded between the two healds in the same way. 2. The relaxation of the twisted edge heald The relaxation of the twisted edge heald is divided into 4 stages: Stage 1: At the moment of opening, the heald yarn “G” is on top of the twisted yarn “H” [Figure 4-2 (a)] Stage 2: Heald “B” is pushed upward, while heald “A” and “D” are pulled downward together [Figure 4-2(b)]. Stage 3: When healds “A” and “B” cross, the skein “H” is under the heald yarn “G” [Figure 4-2(c)]. Stage 4: Heddle “B” and riding heddle “D” are pulled downward together, while heald “A” is pushed upward [Figure 4-2(d)]. 2. Types of electronic edge twisters: Depending on the type of loom used, electronic edge twisters are divided into: electronic edge twisters for rapier looms; electronic edge twisters for air-jet looms; and electronic edge twisters for water-jet looms. device. Each electronic edge twister has various models and specifications, which can be selected according to needs.
