Abstract:
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.
