ABSTRACT:
An apparatus for stretching dough comprising two pairs of rollers and means for imparting vibrations to the dough positioned between the pairs of rollers is provided. In this apparatus, vibrations are imparted to dough, which causes the thixotropic effect in the dough. Such dough can be readily stretched by being subjected to a tensile stress caused by the difference in the peripheral speed of the pairs of rollers. Therefore, dough can be stretched without subjecting it to high pressure during the stretching process.
