METHOD OF HEAT TREATMENT OF ANIDE CORD Russian patent published in 2009 - IPC D01F11/08 D02G3/48 

FIELD: textile, paper.

SUBSTANCE: invention relates to a technique of production of high-strength anide cords used to manufacture tyres and rubber-cord casings in tyre and rubber industry. The production method involves treatment of the anide cord in the hot stretching area at a temperature of 195±5°C and for 31-39 sec with tension of 60-75 kN/cloth. This is followed by thermal stabilisation at 200-210°C with tension of 21-24 kN/cloth for 31-39 sec. This is followed by cooling of the cord cloth to the ambient temperature with tension of 21-24 kN/cloth for 31-39 sec.

EFFECT: invention enables to improve quality of the anide cord and by doing so to improve performance of rubber items.
