Abstract
A method of forming an elastomeric tire component is provided, comprising the following steps. An apparatus is provided which includes a rotating applicator head and a non-rotating portion. The non-rotating portion has an internal channel having a first end in fluid communication with a gear pump and a second end in fluid communication with a first channel of the rotating applicator head. The first channel is substantially aligned with the Z axis. The rotating applicator head further includes a second channel in fluid communication with the first channel, and wherein the second channel is oriented at an angle with respect to a Y axis and is in fluid communication with a nozzle. The method further includes pumping a strip of elastomeric material through said internal channel and then into said first and second channel, and then through an outlet of said nozzle onto a surface. The apparatus further comprising a tongue assembly rotatably mounted to the applicator head and being positioned adjacent said nozzle, wherein said tongue compresses said strip of elastomeric material against said surface.
