[0035] Embodiment 1:

[0036] In the production of double-core filaments, the wire guide wheel unit combination numbered 12 in Table 2 is adopted; that is, a single wire guide wheel unit on one side at the front end and a double wire guide wheel unit on one side at the rear end are adopted on the guide wheel frame 1; realizing the guiding of double-core filaments on one side of the guide wheel frame 1; or adopting the wire guide wheel combination numbered 20 in Table 2; that is, a single wire guide wheel unit on both sides at the front end and a double wire guide wheel unit on both sides at the rear end are adopted on the guide wheel frame 1, realizing the guiding of double-core filaments on both sides of the guide wheel frame 1;

[0037] As Figure 3 shown: The two core filaments in the double-core filaments respectively pass through the double wire guide wheel unit at the rear end of the guide wheel frame 1, and the double wire guide wheel unit is driven to rotate by the frictional force of the two core filaments; then pass through the single wire guide wheel unit at the front end of the guide wheel frame 1 and are twisted with the wrapping filaments on the side, and the wire guide wheel stop detection box 4 detects the double wire guide wheel unit; if it is detected that any wire guide wheel unit on the double wire guide wheel unit stops rotating, the feeding of the core filaments and the wrapping filaments can be controlled;

[0038] In the original production process of the double-core wire, a single wire guiding wheel unit is provided at both the front end and the rear end of the wire guiding wheel frame. One of the core wires does not pass through the single wire guiding wheel unit on the wire guiding wheel frame, and the other core wire passes through the single wire guiding wheel units at the front end and the rear end of the wire guiding wheel frame respectively.
