Analysis and Improvement Measures for Loose Lines in 0° Belt of All-steel Truck and Bus Radial Tire
The reasons for the loose lines in 0° belt of all-steel truck and bus radial tires were analyzed,and the effect of rolling tread on the rubber at the loose line position of the 0° belt cord end was simulated during the tire building process through finite element simulation.By optimizing the building rolling parameters to reduce the strain of the rubber at the 0° belt cord end,the occurrence rate of loose line defects in 0° belt of the tire was reduced from 0.4％to 0.18％,which not only improved the quality of the tire,but also created good economic benefits.
