As shown in FIG. 1, the first double-layer segments 2 are alternately connected with the single-layer segments 1, one single-layer segment 1 is connected between each two first double-layer segments 2, and one first double-layer segment 2 is connected between each two single-layer segments 1. One second double-layer segment 3 is connected between each two single-layer segments 1.

[0021] The first double-layer segment 2 includes a first layer B and a second layer C, and the first layer B is arranged below the second layer C. A width of the first layer B is greater than that of the second layer C.

[0022] The second double-layer segment 3 includes a third layer E and a fourth layer F, and the third layer E is arranged below the fourth layer F. A width of the third layer E is greater than that of the fourth layer F. The fourth layer F has a hollow structure. The hollow structure is filled with yarn or other items to increase user's holding experience.

[0023] As shown in FIG. 1, the second layer C is arc-shaped with respect to the first layer B, forming an arch. The fourth layer F is arc-shaped with respect to the third layer E, forming an arch. The single-layer segment 1, the first double-layer segments 2 and the second double-layer segment 3 are made of elastic fabrics or non-elastic fabrics.

[0024] The elastic fabrics mainly refer to knitted fabrics, or product woven from a first fiber selected at least one from a group consisting of nylon, lycra, modal and the like, or product woven from the first fiber blended with a second fiber selected at least one from a group consisting of cotton, linen, silk, wool and the like.

[0025] Referring to FIG. 2, FIG. 2 is a top view of FIG. 1. A width L1 of the first layer B is greater than a width L2 of the second layer C; a width L1 of the third layer E is greater than a width L3 of the fourth layer F. The single-layer segments 1, the first double-layer segments 2 and the second double-layer segment 3 are woven in one piece.

[0026] In some embodiments, the single-layer segment 1 includes a first single-layer segment A and a second single-layer segment D; the first single-layer segment A and the second single-layer segment D are arranged at two ends of the first double-layer segment 2 respectively, and a first end of the first layer B and a first end of the second layer C are connected to the first single-layer segment A; a second end of the first layer B and a second end of the second layer C are connected with a first end of the second single-layer segment D.

The first end C1 and the second end C2 of the second layer C are respectively arranged at two ends of the second layer C, and the third end C3 is located at the middle of the second layer C. The widths of the first end C1 of the second layer C and the second end C2 of the second layer C are greater than the width of the third end of the second layer C. So that the second layer C presents a wide-narrow-wide effect from the first end C1, to the third end C3 and then to the second end C2.

[0028] A material shrinkage rate of the first layer B is greater than that of the second layer C. So that a length of the first layer B is reduced after weaving the double-layer segment, and then the second layer C presents an arc shape.

[0029] The material shrinkage rate of the first layer B is greater than that of the second layer C. So that the length of the first layer B is reduced after weaving the double-layer segment, and the second layer C presents an arc shape.

[0030] Further, in conjunction with FIG. 4, FIG. 5, FIG. 6, FIG. 7 and FIG. 8, the double-layer handlebar belt with wide and narrow portions of the present disclosure is described: The double-layer handlebar belt with wide and narrow portions as shown in FIG. 1 is formed by interweaving the warp and weft yarns using two weft needles and two sheds.

[0031] Specifically, a spindle of the weaving equipment rotates and brings a steel buckle linkage to perform an eccentric movement, as such a steel buckle seat swings back and forth. When swings back and forth, the steel buckle seat brings a weft aluminum hand to swing in an arc, the weft needles are fixed on the weft aluminum hand, and the weft needles are hooked into the knitting needle with the weft yarn after passing through the sheds through the swing of the weft aluminum hand. Two weft needles pass through the upper and lower sheds, respectively.

[0032] The sheds are opening formed by the up and down movements of the warp yarn, including an upper shed and a lower shed, the upper shed and the lower shed are formed under the drive of a brown frame, an upper shed brown frame stroke is from top to middle, and a lower shed brown frame stroke is from middle to bottom. The upper shed is formed by the up and down movements of the brown frame, and the lower shed is formed by the up and down movements of the brown frame, and the two weft yarns pass through the two sheds respectively, and are interwoven into the double-layer handlebar belt with wide and narrow portions as shown in FIG. 1 by the opening and closing of the sheds.

[0033] In some embodiments, the weaving equipment includes fourteen brown frames which are numbered 1 to 14, respectively. The upper shed is formed by the up and down movements of the second to sixth brown frames, and the lower shed is formed by the up and down movements of the seventh to fourteenth brown frames.

[0034] Specifically, when weaving the single-layer segment 1, all warp yarns are driven by the brown frame to convert from the whole-upper and the middle-upper of the upper structure to the middle-lower and the whole-lower of the lower structure to form the lower shed, and the special Y-shaped steel buckle is positioned between 1 and 2 to weave the lower layer of the single layer segment 1. In some embodiments, as shown in FIG. 4, the first brown frame drives a weft yarn color selection system 20 to connect with the first weft yarn 40, and the second weft yarn is separated from a groove in the first weft needle when the first brown frame moves downwards, and the second weft yarn does not participate in weaving. The groove is groove F as shown in FIG. 5. The second weft needle 30 is woven in conjunction with the first weft yarn 40 to form the single-layer segment 1. As shown in FIG. 6, the second weft needle 30 and the first weft yarn 40 form the single layer segment 1 with the warp yarn when move from middle to bottom driven by the brown frame in the lower shed G. It should be understood that because two weft yarns are needed to weave the first double-layer segment 2, but only one weft yarn is needed when weaving the single-layer segment 1 weaving, the weft yarn color selection system is required to select a target weft yarn to participate in the weaving of single-layer segment 1.

[0035] When weaving the first double-layer segment 2, a part of the warp yarn is transformed from the middle to bottom movements to the middle to top movements under the driven of the brown frame, to form the upper shed. When the first brown frame moves to the top, the weft yarn hooks into the groove in the first weft needle, to participate in weaving. At this time, the first and second weft needles are woven simultaneously to form the first double-layer segment 2. As shown in FIG. 7, the second weft needle 30 and the first weft yarn 40 form the first layer B with the warp yarn in the lower shed G, and the first weft needle 50 and the second weft yarn 60 form the second layer C with the warp yarn in the upper shed H.

[0036] Specifically, the present disclosure is illustrated combined with FIG. 8: when weaving the first double-layer segment 2, the steel buckle raises from a low position, a fixing shaft of the steel buckle moves upwards and the steel buckle also moves upwards, and the warp yarn passes through a lower half of the steel buckle which is narrower, as such a warp yarn density changes from small to large and less weft yarn is delivered. So that, the woven belt changes from wide to narrow, forming the shape of C1 to C3 as shown in FIG. 3.

[0037] The steel buckle moves from the top position to the lower position, the fixing shaft of the steel buckle moves downwards, the steel buckle also moves downward, the yarn passes through an upper part of the steel buckle, and the upper part of the steel buckle is wider, as such the warp yarn density changes from large to small and the weft yarn is delivered faster, so the woven belt changes from narrow to wide, forming the shape of C3 to C2 as shown in FIG. 3.

[0038] For example, when weaving the single layer segment 1, the shed in the steel buckle moves from steel buckle position 2 to steel buckle position 4.

[0039] When weaving the second layer C of the first double-layer segment 2, the shed in the steel buckle moves from steel buckle position 1 to steel buckle position 3, and gradually the shed in the steel buckle moves from the steel buckle position 2 to steel buckle position 3, forming the shape of C1 to C3 as shown in FIG. 3, then the shed in the steel buckle moves from steel buckle position 1 to steel buckle position 3, forming the shape of C3 to C2 as shown in FIG. 3.

[0040] When weaving the first layer B, the shed in the steel buckle moves from steel buckle position 2 to steel buckle position 4.

[0041] The structure and material of the first layer are different from those of the second layer, the material shrinkage rate of the first layer is greater than that of the second layer, and the first layer is shorter than the second layer due to the structure and material shrinkage after the double layer is weaved, so the second layer is arc-shaped relative to the first layer.

[0042] When weaving the second double-layer segment 3, the steel buckle is controlled to move upwards, and the woven yarn moves upwards based on the steel buckle from the first position of the steel buckle to the second position of the steel buckle, and a conveying capacity of the weft yarn is reduced, as such the width of the second layer reduces from the first width to the second width until the weaving is completed. The width of the first position of the steel buckle is greater than that of the second position of the steel buckle.

[0043] Different from the prior art, the present disclosure discloses a double-layer handlebar belt with wide and narrow portions which includes: single-layer segments; first double-layer segments alternately connected with the single-layer segments, and the first double-layer segment includes a first layer and a second layer, the first layer is arranged below the second layer, and a width of the first layer is greater than that of the second layer; second double-layer segments alternately connected with single-layer segments, the second double-layer segment includes a third layer and a fourth layer, the third layer is arranged below the fourth layer, and a width of the third layer is greater than that of the fourth layer; the fourth layer has a hollow structure; the single-layer segment, the first double-layer segment and the second double-layer segment are woven in one piece. Through the above-mentioned mode, the first double-layer segment has two layers with different widths, the production cost can be reduced, the weight of the finished product is reduced due to the reduction of width, and the fourth layer of the second double-layer segment with a hollow structure can be used as a handlebar, which is much more lightweight and comfortable when used, and the user experience is improved.

[0044] Referring to FIG. 9, FIG. 9 is a flow chart of the method for weaving the double-layer handlebar belt with wide and narrow portions according to a first embodiment of the present disclosure, which includes: Step 121: Weaving single layer segments. Step 122: Weaving first double layer segments.

[0045] The double-layer segment includes a first layer and a second layer, the first layer is arranged below the second layer, and a width of the first layer is greater than that of the second layer.

[0046] Step 122 can be used to weave the first layer and second layer, respectively.

[0047] When weaving the second layer, the steel buckle is controlled to move upwards, and the woven yarn moves upwards based on the steel buckle from the first position of the steel buckle to the second position of the steel buckle, and the conveying capacity of the weft yarn is reduced, as such the width of the second layer is reduced from the first width to the second width; the steel buckle is controlled to move downwards, the woven yarn moves downwards based on the steel buckle from the second position of the steel buckle to the first position of the steel buckle, and the conveying capacity of the weft yarn is increased, as such the width of the second layer is increased from the second width to the first width; and the width of the first position of the steel buckle is greater than that of the second position of the steel buckle.

[0048] The present disclosure is illustrated combined with FIG. 8: when weaving the double-layer segment, the steel buckle rises from a lower position, a fixing shaft of the steel buckle moves upwards, and the steel buckle also moves upwards, and the warp yarn passes through a lower half of the steel buckle which is narrower, as such a warp yarn density changes from small to large and less weft yarn is delivered. So that, the woven belt changes from wide to narrow, forming the shape of C1 to C3 as shown in FIG. 3. The steel buckle moves from the top position to the lower position, the fixing shaft of the steel buckle moves downwards, the steel buckle also moves downwards, the yarn passes through an upper part of the steel buckle, and the upper part of the steel buckle is wider, as such the warp yarn density changes from large to small and the weft yarn is delivered faster, so the woven belt changes from narrow to wide, forming the shape of C3 to C2 as shown in FIG. 3.

[0049] For example, when weaving the single layer segment, the shed in the steel buckle moves from steel buckle position 2 to steel buckle position 4.

[0050] When weaving the second layer C of the first double-layer segment 2, the shed in the steel buckle moves from steel buckle position 1 to steel buckle position 3, and the shed in the steel buckle gradually moves from the steel buckle position 2 to steel buckle position 3, forming the shape of C1 to C3 as shown in FIG. 3, then the shed in the steel buckle moves from steel buckle position 1 to steel buckle position 3, forming the shape of C3 to C2 as shown in FIG. 3.

[0051] When weaving the first layer B, the shed in the steel buckle moves from steel buckle position 2 to steel buckle position 4.

[0052] Step 123: Weaving a second double layer.

[0053] Weaving a third layer and a fourth layer, respectively.

[0054] When weaving the fourth layer, the steel buckle is controlled to move upwards, and the woven yarn moves upwards based on the steel buckle from the first position of the steel buckle to the second position of the steel buckle, and a conveying capacity of the weft yarn is reduced, as such the width of the second layer reduces from the first width to the second width. The width of the first position of the steel buckle is greater than that of the second position of the steel buckle.

[0055] The single-layer segments are woven alternately with the first double-layer segments and the second double-layer segment, and the single-layer segments are woven with the first double-layer segments and the second double-layer segment in one piece.

[0056] In some embodiments, the method for weaving the double-layer handlebar belt with wide and narrow portions includes: The structure includes whole-upper, middle-upper, middle-lower and whole-lower which form two sheds, and the lifting of the special Y-shaped steel buckle as shown in FIG. 8 is also adopted. The implementation method is completed by alternately connecting the single-layer segments 1, the first double-layer segments 2 and the second double-layer segment 3.

[0057] When weaving the single-layer segment 1, the whole-upper and the middle-upper of the upper structure is changed to the middle-lower and the whole-lower of the lower structure to form the lower shed, and the special Y-shaped steel buckle is positioned between position 1 and position 2 to weave the lower layer of the single layer segment 1. The steel buckle position 2 corresponds to the first position described above.

[0058] When weaving the first double-layer segment 2, the upper layer structure includes whole-upper and middle-upper, the lower layer structure includes middle-lower and whole-lower, and two sheds are formed, and the special Y-shaped steel buckle rises and falls back and forth between position 2 and position 3 to weave the double-layer segment having an upper layer with a change in width and a lower layer with no change in width. The buckle position 3 corresponds to the second position described above.

[0059] When weaving the second double-layer segment 3, two sheds are used, the upper layer is hollow, and the special Y-shaped steel buckle rises from position 2 to position 3, and the double-layer handlebar belt is woven with the upper layer handle (the fourth layer) and the lower layer (the third layer) with no change in width, and the hollow portion is filled with yarn. The shrinkage rate of the lower layer is greater than that of the upper layer, the upper layer has an arc shape. The double-layer handlebar belt with wide and narrow portions is woven as shown in FIG. 10.

[0060] Different from the prior art, the method for weaving the double-layer handlebar belt with wide and narrow portions of the present disclosure can weave the double-layer handlebar belt with wide and narrow portions as described in the above embodiments. Through the above-mentioned method, the production cost can be reduced, the weight of the finished product is reduced due to the reduction of width, it is more lightweight and comfortable when used, the shape of belt with wide and narrow portions is beautiful, and the user experience is improved.

[0061] In some embodiments, the present disclosure further provides an equipment for weaving a double-layer handlebar belt with wide and narrow portions, and the equipment can execute the method having the above-mentioned technical solutions to weave the double-layer handlebar belt with wide and narrow portions as shown in FIG. 1.
