Calendering apparatus and method for rolling dough

A dough rolling method for calendering a sheet of dough, comprising the steps of:

• supporting a sheet of dough on a conveyor belt;
• feeding the sheet of dough supported on the conveyor belt past an outlet end of the conveyor belt directly into a first space defined between an upper roller and a lower input roller;
• rotating the upper roller and the lower input roller simultaneously as the sheet of dough is fed into the first space and subsequently reducing the thickness of the sheet of dough as it passes through said first space with respect to the thickness of the sheet of dough supported on said conveyor belt;
• subsequently feeding the sheet of dough from said first space directly into a second space defined between the upper roller and a lower output roller, in which a distance between rotation axes of the lower input and output rollers is less than the nominal diameter of the upper roller, and in which the second space has a minimum distance between the upper roller and the lower output roller which is less than a minimum distance between the upper roller and the lower input roller;
• and
• rotating the upper roller and the lower output roller simultaneously as the sheet of dough is fed into the second space and subsequently reducing the thickness of the sheet of dough as it passes through said second space with respect to the thickness of the sheet of dough as it passes through said first space.
