  • Patent number: 5154211
    Abstract: A method and apparatus for filling bakery dough, especially thick, sticky bakery dough, into cavity pans is disclosed. The bakery dough is fed from a source into a housing into which cavity pans are advanced by a conveyor. The cavity pans proceed beneath counter-rotating dough-feeding rollers and advance to a rotating compaction roller which rests under downward spring bias on the upper surface of the cavity pan and which rotates to force the dough into the cavities. The dough in the thus-filled cavities is levelled off and excess removed by a doctor blade or roll to which the pan is then advanced, the doctor blade or roll also being under downward spring-bias to maintain it in contact with the upper surface of the cavity pan being filled.
