[0049] The mesh fabric on the mesh fabric output roller 12 is output under the driving of the traction roller 13, the mesh fabric enters the first flattening roller 21 through the traction roller 13, is flattened by the first flattening roller 21, and enters the right side of the first pressure roller 32 after being flattened by the first flattening roller 21, enters the first pressure roller 32, and the first extrusion layer is compounded on the mesh fabric through the first extrusion die 31.

The mesh belt with the first extrusion layer after being heated is input from the left side of the first composite roller 42, and the second extrusion layer is pressed on one side of the first extrusion layer by the second extrusion die 41.

[0051] The non-woven fabric is output to the left side of the second composite roller 43 by the non-woven fabric output roller 6, and the non-woven fabric is compounded with the second extrusion layer between the first composite roller 42 and the second composite roller 43, so that the non-woven fabric at the positions of the first composite roller 42 and the second composite roller 43 is compounded on the side of the second extrusion layer away from the first extrusion layer, and then the roll material is compounded by the first composite roller 42 and the second composite roller 43.

[0052] The roll material after being compounded is transported to the inside of the cooling assembly 5 for cooling.
