A method for continuously manufacturing multi-layered dough materials containing dough layers comprises the steps of continuously extruding material in a tubular form onto a conveyor belt, stretching the material to a thin strip while being transported, folding and piling up the strip of material and re-stretching the piled up material. An apparatus for carrying out the method comprises a dough feeder comprising a vertical hollow screw and a double-layered annular bottom outlet, first conveyor means, first and second roller assemblies each consisting of rollers progressing along a closed orbit, swing means positioned between the first and second roller assemblies for swinging dough material so as to allow it to be piled up on a second conveyor means in a multi-layered form, the second roller assembly being adapted to stretch the piled up dough material in coaction with the second conveyor means. |
