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.

What is claimed is: 1. A method of forming an elastomeric tire component comprising the steps of: providing an apparatus having a rotating applicator head connected to a nozzle, and a non-rotating portion having 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, wherein flow of elastomeric material entering the first end is parallel to a Y axis; said rotating applicator head being rotatable about a Z axis, said first channel being substantially aligned with the Z axis and said rotating applicator head having a second channel oriented at an angle alpha with respect to the Y axis and in fluid communication with the nozzle, wherein alpha is in the range of about 120 to about 150 degrees with respect to the Y axis; 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, said 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. 2. The method of forming an elastomeric tire component of claim 1 wherein the elastomeric material is compressed and heated simultaneously by said outer surface of the tongue assembly, wherein the outer surface is heated to a temperature in the range of about 200 to about 400 degrees F. 3. The method of forming an elastomeric tire component of claim 1 wherein the surface is a rotating drum. 4. The method of forming an elastomeric tire component of claim 1 wherein the tongue assembly is connected to a damping device.
