Then, the strip rolls on the two fixed long rods 51 are pulled out and pass between the first guide roller 60 and the second guide roller 62, and finally extend from the outlet of the weaving cavity 45. Then, the two rotary motors 47 are controlled to work respectively, so that one strip roll is located slightly below the horizontal plane, and the other strip roll is located at the top end of the vertical direction. Then, the free end of the strip roll on the U-shaped support 54 is pulled out and passes between the other two strip rolls. Then, the strip on the two strip rolls on the fixed long rods 51 is continuously released. During the releasing process, the strip roll originally located slightly below the horizontal plane moves to the top end of the vertical direction, and the strip roll originally located at the top end of the vertical direction moves to the position slightly below the horizontal plane. After the positions of the two strip rolls are exchanged, the piston end of the cylinder 50 of the U-shaped support 54 holding the strip roll is continuously extended, so that the strip roll moves to the position of the other U-shaped support 54, and the strip roll is clamped by the electrically controlled clamping jaw 55 on the other U-shaped support 54. Thus, one weaving cycle is completed, and the above-mentioned actions are repeated to continuously weave the strip roll.

[0073] In the attached drawings, Figure 17 The finished product schematic diagram of weaving two raw material rolls 66 and one strip roll 57 is shown in the attached drawings. The material of the strip roll 57 used in the weaving process is flexible, so as to prevent the problem of bending and breaking during weaving.
