Abstract
A method and apparatus for continuously manufacturing multi-layered dough materials containing at least dough layers comprising 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. The apparatus comprises a dough feeder comprising a vertical hollow screw and a double-layered annular bottom outlet, a first conveyor means, a first roller assembly consisting of rollers progressing along a closed orbit, a swinging means positioned between the first and the second roller assemblies for swinging dough material so as to allow it to be riled up on a second conveyor means in a multi-layered form, and a second roller assembly similar to the first roller assembly for stretching the piled up dough material in coaction with the second conveyor means.
