英文摘要: |
The causes of cord exposure at crown groove,crown centre,shoulders,beads and inner surface are analysed. Their precautions in structure design ,processing technology and equipment are proposed:the different extruder die of tread should be used for the tire of same size with different tread patterns;the contour at shoulders and the gauge of inner liner should be reasonably designed;the operation requirements in various stages,such as calendering,extruding,building,shaping and curing,should be strictly carried out;the operating conditions of curing press should be regularly checked,the worn and aged parts should be replaced in time. |
