This line produces endless breaker material from rubber compound and steel cord wires of the required width and angle and winds this material automatically onto reels ready for post-processing in tire building machines.
The production of the breaker material is done in two stages. First one endless strip having longitudinally steel cord wires is produced by means of extrusion, after that this strip is cut under an angle and length corresponding with the dimensions of the required breaker material. The cut strip is positioned on a conveyor and spliced together to the already cut strips to form breaker material. After that the endless breaker material is wound onto a roll. With this systems endless breakers can be produced from 70 – 500 mm with an angle between 18° - 30°, the applied end count is between 13 to 24 EPI.
