2. When the original opening is corrected, a plurality of spiral threads are reserved at two ends of the spiral net piece in the length direction, and the reserved spiral threads are disassembled and removed after the operation of ironing and filling the threads, so that a new original opening generated on a final product is ensured, and the structure is regular and does not deform; therefore, the reserved spiral wire can protect the original opening part of the final product and avoid deformation during heating and shaping operation after original opening correction, (in the heating and shaping operation after original opening correction, the reserved spiral wire protects the spiral wire on the inner side of the reserved spiral wire from deformation and only the reserved spiral wire deforms), and thus, after the reserved spiral wire is disassembled and removed, a new original opening which is not deformed can be obtained, so that the difficulty of original opening splicing of a purchaser is reduced, the quality of original opening splicing of the purchaser is improved, and no double-ring bulge is generated during original opening splicing of the purchaser.
3. The invention carries out side correction before the original correction, and can improve the regularity of the spiral net piece and avoid the influence on use caused by the formation of the spiral net piece in a parallelogram shape through the side correction.

sequentially and alternately splicing a plurality of spiral wires with opposite spiral directions into a spiral mesh belt A11, wherein the spiral directions of adjacent spiral wires of the spiral mesh belt A11 are opposite as shown in figure 7; the splicing in the step 1 adopts the splicing method described in the embodiment 1;
in the splicing process of the step 1, no double rings are ensured when ring structures are alternately spliced;
after the spiral mesh belt A is spliced, as shown in FIG. 6, the side edge of the spiral mesh belt A tends to incline;
step 2-1, disassembling: disassembling the spiral mesh belt A11 into a spiral mesh sheet A12;
disassembling the spiral mesh belt A11 into a plurality of spiral meshes A12, wherein a plurality of spiral meshes A12 are arranged in sequence and keep the sequence unchanged; during disassembly, when the disassembly position is selected, the spiral directions of the spiral wires at the two ends of each spiral net piece A are ensured to be the same, and the spiral directions of the spiral wires at the end parts of the adjacent spiral net pieces A are ensured to be opposite; 2-1, adopting the disassembling method of the embodiment 2;
step 2-2, overturning and splicing: sequentially overturning the spiral net pieces A12 at intervals to enable the oblique directions of the oblique edges of the adjacent spiral net pieces A12 to be opposite, and then sequentially splicing the spiral net pieces A into a spiral net belt B13; 2-2, the splicing method of the embodiment 1 is adopted, and no double rings are ensured in the splicing process of the step 2-2;
the step of splicing again still adopts single-wire splicing, and the single wire used for splicing the spiral net piece A into the spiral net belt B is set as the single wire A6;
sequentially overturning the disassembled spiral meshes A11 at intervals refers to overturning all odd-numbered spiral meshes A or overturning all even-numbered spiral meshes A; the inclination angle of the side edge of the turned spiral mesh A is changed, so that the inclination directions of the turned spiral mesh A and the non-turned spiral mesh A are opposite, and the turning of the spiral mesh A adopts an interval turning mode, so that after the turned spiral mesh A and the non-turned spiral mesh A are alternately spliced again, a spiral mesh belt B13 with wavy side edges can be formed, and the inclination degree of the side edge of the spiral mesh belt A is corrected;
step 3, heating and shaping: heating and shaping the spiral mesh belt B13;
heating and shaping the spiral mesh belt B13 at the temperature of 130 ℃ by using a shaping machine until the elongation of the spiral mesh belt B13 reaches 25%, cooling to room temperature, and then carrying out subsequent operation;
step 4, disassembling: disassembling the spiral mesh belt B13 into a spiral mesh sheet B14;
during disassembly, the spiral directions of spiral wires at two ends of the spiral net piece B14 are ensured to be opposite;
disassembling the spiral mesh belt B into a plurality of spiral meshes B, and reserving two ends of the spiral meshes B14 in a length direction in a way of being larger than a specified size to form reserved spiral wires 19; the number of the reserved spiral threads at each end is 1-5 (1 spiral thread is reserved on each side in the embodiment); step 4, the disassembling method adopted in the disassembling process of the embodiment 2;
after purchasing the spiral mesh product, the purchaser needs to splice the spiral mesh product into a ring for use; therefore, the ring structure of the spiral wire at both ends of the spiral mesh used by the purchaser is generally considered as the original opening.
In traditional spiral mesh sheet production technology, spiral mesh sheet B has already carried out the heat setting before disassembling, the operation of wearing the flat silk and the operation of ironing flat silk, spiral mesh sheet B disassembles into spiral mesh sheet B after, only need carry out the banding glue can, spiral mesh sheet B also need not reserve, consequently, in the conventional art, the loop structure of spiral silk at spiral mesh sheet B both ends promptly leaves the original mouth that the buyer carries out the concatenation for, the loop structure of spiral silk at spiral mesh sheet B both ends corresponds with the original mouth in the conventional art, consequently, here, the original mouth position in the conventional art is called as spiral mesh sheet B both ends, for short for traditional original mouth position.
Step 5-1, disassembling: disassembling the spiral mesh sheet B14 into a part A15 and a part B16;
when the spiral net piece B14 is disassembled into the part A15 and the part B16, the spiral net piece B is disassembled from any position, but after the disassembly is required to be ensured, the spiral directions of the spiral wires at two ends of the part A are consistent, the spiral directions of the spiral wires at two ends of the part B are consistent, and the spiral direction of the spiral wire at the end part of the part A is opposite to the spiral direction of the spiral wire at the end part of the part B.
Step 5-2, turning:
respectively overturning the part A14 and the part B15 in a positive and negative way, so that the positions of the outer ends and the inner ends of the part A and the part B are interchanged, and after overturning, the original outer ends of the part A and the part B are positioned at the inner sides to form new inner ends, so that the original outer ends of the part A and the part B are adjacent to each other in position, and the original inner ends of the part A and the part B are positioned at the outer sides to form new outer ends; (that is, both ends of the spiral mesh B in the longitudinal direction are turned over and then are immediately adjacent);
step 5-3, splicing;
splicing the turned part A14 and the turned part B15 again by using monofilaments 5 to form a spiral net piece C17; thereby shifting the traditional original opening positions at the two ends of the spiral mesh belt B to the middle part of the spiral mesh sheet C; the splicing in the step 5-3 adopts the splicing method in the embodiment 1, and the splicing in the step 5-3 ensures that no double rings exist when the ring structures are alternately spliced, so that the spliced spiral mesh belt C can generate bulges certainly due to the absence of the double rings;
in the embodiment, the monofilaments used for the part a and the part B are defined as the monofilaments B7, and the position of the monofilament B7 on the spiral mesh C corresponds to the traditional original position of the spiral mesh B, so that the position corresponding to the monofilament B7 on the spiral mesh C is also defined as the traditional original position;
the two ends of the spiral net piece C17 form a new original opening 29 after the reserved spiral wire 19 is removed in the subsequent process; because the two ends of the spiral mesh C17 are obtained by disassembling two adjacent spiral wires on the spiral mesh B, even if the reserved spiral wires 19 are disassembled to form new original openings 29, the new original openings 29 at the two ends are also obtained by disassembling two spiral wires with similar positions on the spiral mesh B14, and therefore, even if no professional tool is provided, no professional operator is provided, the buyer can easily realize the splicing of the new original openings at the two sides without generating double rings and bulges; at this time, the traditional original opening positions at the two ends of the spiral mesh piece B are shifted to the middle part of the spiral mesh piece C, namely the position of the monofilament B7, by the spiral mesh piece C obtained after splicing; thereby realizing the correction of the original position;
step 6, splicing: splicing the spiral net sheets C17 into a spiral net belt C20;
