Abstract
A flat sheet comprising a layer of fat sandwiched between two layers of dough is produced using a coextrusion die having two slot-like orifices. In order to avoid distortion of the sheet due to the dough leaving the center portion of the outer slot-like orifice more quickly than the end portions thereof, multiple augers or other drive means are used and the drive means which drive the dough through the end portions of the orifice operate more quickly than those which drive the dough through the center portion of the orifice. The coextruded sheet may be laminated, rolled and cut to form multi-layered bakery products.
