The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] By using the cord cutting and splicing method of the present application, after determining the cord length required for a single tire by the size of the tire, that is, after determining the first cord length, the second cord length between two adjacent self-joints of the cord to be cut and the minimum value of the first spacing that does not affect the dynamic balance of the tire are calculated, so as to obtain the third cord length of the cut material segment cut from the cord, thereby ensuring that after cutting the cut material segment of the third cord length from the cord, the cord can be cut N times with the first cord length, and the cord obtained by each cutting in the N times can meet the condition of not affecting the dynamic balance of the tire, that is, when the cord is cut each time and used to produce tires, the distance between its joint and its own joint is greater than the minimum value of the first spacing. Therefore, by using the cord cutting and splicing method of the present application, the number of cutting times of the cord joint can be effectively reduced, thereby improving production efficiency and reducing cord waste.

[0028] That is to say, in the present application, the minimum value of the first spacing between the cut joint and the adjacent self joint on the tire is the minimum value of the spacing between the two joints that does not affect the dynamic balance of the tire.

Further optionally, at this time, the third curtain fabric length may also be greater than the minimum value of the first spacing. Of course, the specific value of the third curtain fabric length can be determined according to the specific production situation. That is to say, in the present application, the third curtain fabric length may also be less than the minimum value of the first spacing.

[0030] Of course, in the present application, during the process of performing N consecutive cuts on the cord with the first cord length, after N-1 consecutive cuts, the cut material segment obtained before N consecutive cuts is sewn with the cord head at this time and the Nth cut is performed.
