Claims
- 1. An improved sheeter machine serving to receive a masa dough from a supply thereof comprising;
- a frame,
- front and back sheeter rolls on said frame, wherein said rolls have substantially cylindrical exterior surfaces and first and second shafts, respectively,
- said first and second shafts being rotatably mounted on said frame in a substantially parallel relationship;
- said rolls being arranged so that their exterior surfaces are spaced slightly apart so as to define a nip disposed to receive masa dispensed from the supply thereof;
- first and second variable speed drive means coupled to said first and second shafts serving to rotate said front and back rolls respectively to establish and control, over a variable range, a differential adhesion characteristic between the masa material to be sheeted and the exterior surfaces of each of said sheeter rolls so that the sheeted material below the nip separates from the back roll while adhering to the front roll;
- rotatable cutter means extending laterally of the path of masa travel serving to engage and cut the masa against the front roll as it rotates, the masa being cut into predetermined shapes characteristic of the cutter means;
- stripper wire means fixedly mounted on said frame engaging said front roll for lifting the cut pieces of masa from the exterior surface of the front roll,
- the co-action of the fixed stripper wire with the rotating masa pieces tending to compress the masa pieces to shrink in the direction of travel to a dimension less than the nominal cut dimension; and
- third variable speed drive means coupled to said cutter means serving to rotatably drive said cutter means at selected rotational speeds so as to obtain relative rotational surface speeds the same as, and slower than, and faster than the rotational surface speed of said front roll permitting control over the cut length of the masa pieces so as to obtain an accurate cut length of the sheeted masa pieces irrespective of variables in the masa qualities and the sheeter rolls relative speeds.
- 2. The sheeter machine of claim 1 wherein said exterior surface of said front roll has substantially greater dough attracting "tooth" than the surface of the back roll.
- 3. The sheeter machine of claim 1 wherein said first and second drive means serve to drive said sheeter rolls shafts so that the rolls rotate at different exterior surface speeds such that the speed of said front roll is no slower than the surface speed of the back roll.
- 4. The sheeter machine of claim 1 wherein one of said rolls is made to a smaller diameter than the other roll.
- 5. The sheeter machine of claim 1 wherein the front roll is convex in profile and the back roll is concave and complimentary in profile to the first roll.
