[0031] The cutting mechanism 2 is located between the cloth-pulling roller assembly 1 and the heating roller assembly 4. It includes two guide rails 21, a blade holder 22, and a blade 23. Two parallel guide rails 21 are provided, through which the double-layer fabric passes. The blade holder 22 is mounted on the two guide rails 21 and can be moved and positioned along their lengths. The blade holders 22 are provided in two sets, each with two blades 23 mounted on each set. The blades 23 are positioned at the corresponding edges of the double-layer fabric. The cylindrical fabric passes through the cutting mechanism 2, forming two sheets of double-layer fabric. The blades 23 can be either stationary blades or rotating electric blades.

[0032] The heating roller assembly 4 includes a first heating roller 41 and a second heating roller 42. The heating roller assembly 4 receives the double-layer fabric from the cloth-pulling roller assembly 1. The double-layer fabric is routed around the first and second heating rollers 41, 42. The route comprises a first heating path, with one side facing and contacting a portion of the outer circumference of the first heating roller 41, and a second heating path, with the other side facing and contacting a portion of the outer circumference of the second heating roller 42.

[0036] The present application will be further described below with reference to a specific working process.

[0037] The circular machine weaves to form a tubular fabric and conveys it downward; the tubular fabric is pulled down by the cloth-pulling roller group 1 to form a stacked double-layer fabric; the double-layer fabric output by the cloth-pulling roller group 1 first passes through the straightening roller 31 and is conveyed downward. At this time, the double-layer fabric is in a vertical plane and is conveyed downward. When the double-layer fabric passes through the cutting mechanism 2, the two edges are cut by two blades 23, forming two pieces of double-layer fabric; then the double-layer fabric passes between the two upper guide rollers 32 and enters the heating roller group 4. The winding path of the double-layer fabric has a first heating path that is wound around a section of the outer circumference of the first heating roller 41 and is in contact with the first heating roller 41. , and a second heating path is formed by winding around a section of the outer circumference of the second heating roller 42, with the other side facing and contacting the second heating roller 42; specifically, the two pieces of the double-layer cloth are divided into a first sheet and a second sheet. During the first heating path of the double-layer cloth, the first sheet is contacted with the first heating roller 41 and heated at a higher temperature, and the second sheet is heated by heat conduction between the cloths; during the second heating path of the double-layer cloth, the second sheet is contacted with the second heating roller 42 and heated at a higher temperature, and the first sheet is heated by heat conduction between the cloths; therefore, the heating and setting effects of the two pieces of cloth finally outputted as the double-layer cloth are highly consistent.

[0038] After passing through the heating roller group 4, the double-layer cloth passes between the two lower guide rollers 33 and is output to both sides. The two groups of winding mechanisms 5 wind up the two pieces of cloth into two cloth rolls.

[0039] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this.
