  • Patent number: 4621997
    Abstract: An apparatus for manufacturing wafers is disclosed that includes a pair of rolls each containing cavities that form the wafers. The cavities each have outer edge walls that extend from the bottom portion of the cavity at an obtuse angle and the two rolls are arranged so that the cavities become effectively mirror images of each other as they engage at the nip. The cavities also have portions rising from the bottom thereof that impress a design substantially equal from both sides to proclude warping of the bread.

  • Patent number: 4469476
    Abstract: Wafers are produced by guiding a sheet of bread having friable outer crusts and a relatively soft center through wafer forming apparatus. The apparatus includes a pair of rolls, one of said rolls, i.e., a cutting roll having one or more wafer forming recesses or cavities therein and the other roll being a pressure roll which operates in rolling engagement with the cutting roll. As the sheet of bread is introduced into the nip formed between the two rolls the pressure roll acts to press the bread into the cavity or cavities on the cutting roll and into engagement with the edges of the cavity or cavities to cut wafers from the sheet of bread. Each cavity is configured to have a bottom surface which rises as a gradually tapering wall to a cutting edge which is coterminious with the surface of the cutting roll.

Continuous production of wafers is possible with the edges of the wafers being sharply defined, free of undesirable crumbling and devoid of fracture lines.
