Abstract: Apparatus for continuously forming individual products pieces containing filler therein and having large perforations in the top layer. A first continuous flat dough sheet is formed and transported on a conveyor belt. Portions of the filler are periodically deposited on the first dough sheet. A second continuous flat dough sheet is formed and transported on a conveyor belt of a material to which the dough of the second continuous flat dough sheet adheres in response to pressure. A device for moving cutting elements through the second dough sheet forms a multitude of holes and presses the perimeter of each dough piece therein so as to adhere to the conveyor belt. An arrangement lifts the second dough sheet off of the conveyor belt means without disturbing the cut out dough pieces adhered thereto.
