摘要： A method and apparatus for applying a blended rubber composition directly onto a tire building drum or core is described. The method includes the steps of extruding a first rubber compound through a main extruder and a main gear pump. A second rubber compound is extruded through a second extruder and into a second gear pump. The output from the second gear pump is fed into the main extruder. The ratio of the first compound to the second compound is varied by adjusting the speed of the main gear pump and the speed of the second gear pump. A continuous strip of rubber formed of said first compound and said second compound is layed directly onto a tire building machine to form a first layer of rubber having a first blend ratio. The speed of the main gear pump and the second gear pump is adjusted to obtain a second blend ratio of said first compound to said second compound, and then a strip of rubber formed of said second blend ratio is applied to the tire building drum or core.
