ABSTRACT:
A mold box assembly includes a rectangular mold box frame having a substantially vertical divider plate mounted on the frame and extended part-way into it from an the upper side of the frame. A pair of rectangular restrictor plates are disposed vertically in the mold box from side to side and extend to the same depth as the divider plate. Wet product mix is dropped onto the box and is thereafter compressed with a shoe assembly. The shoe assembly includes a pair of shoes that extend from one side of the mold box to the other and have a thickness that allows them to be interleaved with the restrictor plates. The shoes are lowered to the lower edge of the restrictor plates. Simultaneously, another shoe mounted on the head plate compresses product on the other side of the divider plate so a higher level thus forming a header block having a first lower height formed beneath the restrictor plates and a second higher height formed on the other side of the divider plate.
