ABSTRACT:
An apparatus for stretching a plastic raw material having viscoelasticity, such as bread dough or confectionery dough. A linear motor or built-in motor is provided relative to rollers which pass around an endless roller path. A drive power of the motors for the advancement of the rollers is effectively transmitted by the friction of the rollers with the raw material or rails so as to simply rotate the rollers around their axes and along an endless roller path, thereby performing effective stretching of the plastic raw material.
