A method for winding an S-1 crown band

Abstract

The present invention discloses an S-1 cap band winding method, comprising the following steps: step 1: winding the cap band to the left with a stroke of 16 mm per turn to the left edge of the total width of the cap band, for a total of two turns; step 2: performing a full circle locking ring on the left edge; step 3: starting to wind the cap band to the right with a stroke of 16 mm per turn to the center of the entire cap band, the number of winding turns = (half-7.5 of the total width of the cap band) / 16*360; step 4: performing a half circle locking ring on the central area of ​​the entire cap band; after the above four steps of winding are completed, symmetrical winding is performed; through the entire winding process, an additional circle of the cap band is wound around the area 15 mm away from the center of the tread, so that the material in this area is rapidly thickened. The present invention is simple and easy to operate, and is easy to operate and adjust, so that the material in the area 15 mm away from the center of the tread is rapidly thickened; after the optimized finished tire is vulcanized, there is no rubber deficiency in the center of the tread, and the improvement is obvious.

Description

Technical Field

[0001] The present invention relates to the field of tire manufacturing, and in particular to an S-1 cap band winding method. Background Art

[0002] The FRD26 series tires produced on VMI's single-stage tire machine are UHP high-performance tires. Due to their unique tread compound and central willow-leaf steel plate design, more material is required in the center area. If this material is insufficient, it is very easy to cause center rubber deficiency.

[0003] The existing crown strip winding method is Figure 3 To improve the center rubber shortage of the tread, conventional methods are to adjust the tire circumference or the tread mouth size. Adjusting the tire circumference has little effect and has a certain impact on tire performance; while adjusting the tread mouth size is time-consuming and easily causes material waste. If the crown strip winding method is changed to Figure 2 This approach will also significantly increase the use of crown strips. Summary of the Invention

[0004] The object of the present invention is to provide an S-1 crown band winding method to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] An S-1 crown band winding method comprises the following steps:

[0007] Step 1: Wrap the strip flatly to the left with a stroke of 16mm per turn to the left edge of the total width of the crown strip, wrapping it twice in total;

[0008] Step 2: Lock the left edge for a full circle;

[0009] Step 3: Start to wind the crown strip to the right with a stroke of 16mm per turn to the center of the entire crown strip. The number of turns = (half of the total width of the crown strip - 7.5) / 16 * 360;

[0010] Step 4: Lock the center area of ​​the entire cap strip for half a circle; after completing the above 4 steps of winding, perform symmetrical winding; through the entire winding process, the area 15mm away from the center of the tread is wound with one more circle of cap strip, so that the material in this area is quickly thickened.

[0011] Compared with the prior art, the present invention has the following advantages: the present invention is simple and easy to implement, and convenient to operate and adjust, so that the area 15 mm away from the center of the tread is wrapped with an extra circle of cap strip, thereby quickly thickening the material in this area; after the optimized finished tire is vulcanized, there is no rubber deficiency in the center of the tread, and the improvement is obvious. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a flow chart of the S-1 crown band winding method of the present invention.

[0013] Figure 2 This is a diagram showing how to change the winding method of the existing crown strips.

[0014] Figure 3 This is a diagram of the existing crown strip winding method. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] An S-1 cap band winding method, characterized by comprising the following steps:

[0017] Step 1: Wrap the strip flatly to the left with a stroke of 16mm per turn to the left edge of the total width of the crown strip, wrapping it twice in total;

[0018] Step 2: Lock the left edge for a full circle;

[0019] Step 3: Start to wind the crown strip to the right with a stroke of 16mm per turn to the center of the entire crown strip. The number of turns = (half of the total width of the crown strip - 7.5) / 16 * 360;

[0020] Step 4: Lock the center area of ​​the entire cap strip for half a circle; after completing the above 4 steps of winding, perform symmetrical winding; through the entire winding process, the area 15mm away from the center of the tread is wound with one more circle of cap strip, so that the material in this area is quickly thickened.

[0021] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
