  • Patent number: 8071151
    Abstract: A dual deposit stencil apparatus for discharging filler materials onto parallel lanes of base cakes comprises a stencil tube having two inlet openings, one communicating with a source of first filler material, and the other communicating with a source of second filler material. The stencil tube has four discharge openings therein. A stencil carried on the stencil tube has pairs of openings therein for receiving two filler materials. Provided in the stencil tube are a first shutoff valve and a second shutoff valve. First and second actuating mechanisms control the shut off valves and are coordinated to simultaneously provide first and second filler material to each pair of openings in the stencil. A wire mechanism cooperates with the stencil for simultaneously removing the first and second filler materials from each pair of openings.
