1.Strictly control the rolling process conditions, choose the appropriate temperature, speed, pressure and contact area of the hot roller according to the type, diameter and thickness of the tube, and adjust the distance between the front and rear rollers at any time.

2. The adhesive tape should maintain a large and even tension during the rolling process. As the thickness of the adhesive tape is uneven or there are sampling holes, the adhesive tape of the same model can be properly inserted.

3. The backing cloth must be flat when it is inserted, and remove the rewind when there is a discount.

4. The end of the adhesive tape must also be flat when it is inserted. When it is wrinkled or stuck to the rear roller or the upper roller, it must be stopped, and the wrinkled part must be removed and then re-rolled.

5. The temperature of the hot roller should be measured at any time before and during the coiling process, and should not be coiled if the temperature does not meet the process regulations.

6. During the rolling process, cooling water should be passed through the rear roller and the upper roller, and they should be cleaned with alcohol frequently to prevent the adhesive tape from wrinkling and foaming.

7. When rolling, the aging, discounting, curling, joints and sleeve dirt in the tape cloth bundle should be cut off with a knife. The tape cloth should not stay on the hot roller for too long when the upper pressure roller is raised.

8. After the rubber cloth tube is rolled into a blank, it should be rolled for 3~5min to ensure the quality of the product.

9. When a thick layer of rubber is formed on the heat roller, it must be stopped and scraped off to prevent the rubber from being caught in the product. Generally, the rubber cloth tube and glass cloth tube should be shoveled once every 3 rolls. Otherwise, the rubber skin is too thick, which will affect the temperature of the hot roller, and the resin will not melt at low temperature, which will affect the performance.

10. When the tape is slightly skewed, the end of the laminated tube may be unevenly rolled, you can adjust the tension roller, generally you can also use a knife to cut one side of the tape to adjust.

11. In order to clean the rubber skin conveniently, the surface of the hot roller should be coated with a release agent; for easy removal of the tube, apply a release agent on the surface of the tube core.
