The invention provides a method for forming a coextruded strip. One or more embodiments of the present invention provide a method for applying a dual compound coextruded continuous strip of a first compound and a second compound, the method comprising a first extruder for processing a first compound and a second extruder for processing a second compound, wherein the outlet from the first extruderis in fluid communication with a first channel of a housing, and the outlet from the second extruder is in fluid communication with a second channel of the housing, wherein a gear pump is positioned in each channel, wherein a nozzle is in fluid communication with an outlet of the first channel and an outlet of the second channel, and a coextruded continuous strip is produced. The ratio of the first compound to the second compound may be adjusted instantaneously. 用于形成轮胎部件的方法。本发明的一个或更多个实施例提供了一种用于敷贴第一化合物和第二化合物的双化合物共挤出连续条的方法，该方法包括用于处理第一化合物的第一挤出机和用于处理第二化合物的第二挤出机；其中，来自第一挤出机的出口与壳体的第一通道流体连通，并且来自第二挤出机的出口与壳体的第二通道流体连通；其中，齿轮泵定位在每
