DETAILED DESCRIPTION OF THE INVENTION

[0026] Please refer to FIG. 3 to FIG. 6, the manufacturing method 2 of the curtain ladder string of the present invention, the steps includes: [0027] a. weaving a ladder string body 3, and weaving one of the edge rings 33 every certain distance along a side rope 31 of the ladder string body 3; [0028] b. the edge rings 33 on the side rope 31 are provided to knit a hollow mesh tube 4, a drawstring 5 is provided to pass through inside the hollow mesh tube 4; [0029] the curtain ladder string A manufactured by the above steps is provided for assembling curtains to achieve the purpose that the drawstring 5 does not be pulled out, to ensure safety in use and convenience of operation.

[0030] The manufacturing method 2 of curtain ladder string of the present invention is provided to achieve consistent production process and fully automated production, to thereby reduce manufacturing costs.

[0031] In the above step a, each of the edge rings 33 is woven every certain distance along a side rope 31 of the ladder string body 3, a lead line 34 is further passed through the edge rings 33, the lead line 34 is provided to keep the edge rings 33 in the same direction for knitting the hollow mesh tube 4 and the edge rings 33 together (please refer to the structure in FIG. 7 to FIG. 9).

[0032] As shown in FIG. 4 to FIG. 6, the structure of the curtain ladder string A of the present invention includes:

[0033] A ladder string body 3, two side ropes 31 are respectively set on its two side, at least one lateral support line 32 is set every certain distance between the two side ropes 31, two ends of the at least the support line 32 are respectively connected to the two side ropes, the feature is: [0034] one of the edge rings 33 is woven every certain distance on the outside of each side rope 31, the edge rings 33 are provided to knit two hollow mesh tubes 4, a drawstring 5 is provided to pass through inside each hollow mesh tube 4.

[0035] Each hollow mesh tube 4 is arranged in parallel with one of the side ropes 31.

[0036] The structure of the curtain ladder string A of another embodiment of the present invention is shown in FIG. 7 to FIG. 9, which includes: [0037] a ladder string body 3, two side ropes 31 are respectively set on its two side, at least one lateral support line 32 is set every certain distance between the two side ropes 31, two ends of the at least the support line 32 are respectively connected to the two side ropes 31, the feature is: [0038] one of the edge rings 33 is woven every certain distance on the outside of the side ropes 31, two lead lines 34 are further passed through the edge rings 33 on each of the side ropes 31 respectively, the edge rings 33 are provided to knit the hollow mesh tubes 4, a drawstring 5 is provided to pass through inside each of the hollow mesh tubes 4.

[0039] Each hollow mesh tube 4 is arranged in parallel with one of the side ropes 31.

[0040] The above ladder string body 3, at least one lateral support line 32 is set every certain distance between its two side ropes 31. There are many type of ladder strings, and the ideal combination is setting two support lines 32 as a group, two support lines 32 are set every certain distance. As for the group of two support lines 32, it can be an overlapping parallel arrangement, and it also can be an up-and-down arrangement with a small interval (as shown in FIG. 1) or other arrangements. Since the structure of the support lines 32 and the side ropes 31 is the prior art, not technical features of the present invention, so it is not described here.

[0041] By the above structure, each hollow mesh tube 4 is net structure, it can be compressed to a minimum volume when the curtains are folded, so the structure would not be in a large tangle to affect the appearance of curtains. Furthermore, the hollow mesh tubes 4 are net structure, the meshes are small, so children cannot put their fingers in and the drawstrings 5 can not be pulled out, to thereby achieve safety in use and convenience of operation.
