An apparatus for forming a continuous preparation ply of the type used to make vehicle tires from preparation ply sections having nonmetallic cords. An infeed conveyor successively feeds the preparation ply sections to a butt splicing machine that joins the ends of the two preparation ply sections to form a butt joint. A gum strip applier receives the continuous preparation ply from an outfeed conveyor and applies a gum strip over the butt joint. A method is provided for forming a continuous preparation ply by first automatically forming a butt joint, and thereafter automatically placing a gum strip on the butt joint.
