Abstract
An improved applicator die for alternately depositing different liquid coating materials on a moving web comprises a die body having switch bars for opening and closing respective flow passageways for supplying the different liquid coating materials to an elongated coating orifice from respective manifolds. The switch bars, flow passageways and manifolds are substantially as wide as and substantially parallel to the coating orifice of the die whereby changeover between different coating materials can be made very rapidly.
