Abstract
Abstract The apparatus has an extruding means and a spreader means whereby a continuous dough sheet is formed. To preserve the "softness" within the dough and the finished cooked product the extruding means has a double feed screw housing preferably disposed side-by-side and having their outlets joined by a Y-type fitting to form a single feed conduit which is coupled to a spreader means having a downwardly distending outwardly flaring passageway. To prevent dough from sticking to the surfaces of the passageway the opposing triangular shaped surfaces are each provided with a plurality of parallel grooves oriented at an angle to the dough path travel. To ensure no separation of dough when in the sheet form, the feed conduit is provided with a twister or helical thin member which ensures the interface surface within the dough is oriented at an angle of less than 90 degrees with the elongated cross-section the spreader means.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
An extruder and dough spreader apparatus for viscious plastic material, said apparatus comprising: a body having an opening disposed on its top for feeding said material therein and at least one opening disposed on its side; a pair of conveyor screws parallely disposed within said body and extending through said side opening; a pair of tubular housings fixed to said side opening and each of said housings enclosing a respective screw; a Y-type fitting having two inlet ducts communicating with an outlet duct; each of said inlet ducts on said fitting being coupled to a respective one of said housings; a spreader having an inlet passage and an elongated egress; said inlet passageway of said spreader being coupled to said outlet of said Y-type fitting; said conveyor screws being disposed side by side substantially in the same horizontal plane; each of said conveyor screws having a larger outer diameter in its portion adjacent said body than its outer diameter in its portion adjacent said Y-fitting; each of said housings having a larger inner diameter in its portions adjacent said body than its inner diameter in its portion adjacent said Y-fitting.
Claim 2
Dependent Claim
190 words
An extruder and dough spreader apparatus for viscious plastic material, said apparatus comprising: a body having an opening disposed on its top for feeding said material therein and at least one opening disposed on its side; a pair of conveyor screws parallely disposed within said body and extending through said side opening; a pair of tubular housings fixed to said side opening and each of said housings enclosing a respective screw; a Y-type fitting having two inlet ducts communicating with an outlet duct; each of said inlet ducts on said fitting being coupled to a respective one of said housings; a spreader having an inlet passage and an elongated egress; said inlet passageway of said spreader being coupled to said outlet of said Y-type fitting; said conveyor screws being disposed side by side substantially in the same horizontal plane; each of said conveyor screws having a larger outer diameter in its portion adjacent said body than its outer diameter in its portion adjacent said Y-fitting; each of said housings having a larger inner diameter in its portions adjacent said body than its inner diameter in its portion adjacent said Y-fitting.
Claim 3
Dependent Claim
72 words
The apparatus of claim 1 wherein said spreader comprises: an aperture plate shaped substantially triangular having an aperture disposed at one corner thereof and having said inlet passageway communicating with said aperture; a cover plate shaped substantially similar to said aperture plate and disposed in a back-to-back relationship to said spreader plate to form a distending outwardly flaring passageway therebetween and having an elongated egress disposed opposite said aperture on said plate.
Claim 4
Dependent Claim
50 words
The apparatus of claim 2 wherein: said distending outwardly flaring passageway becomes thinner as the passageway becomes removed from said aperture in said plate; a releasing ridge is disposed on each of said plates and extending into said flaring passageway and each of said ridges are disposed near said egress.
Claim 5
Dependent Claim
55 words
The apparatus of claim 3 wherein: each of said plates having formed on their respective facing surfaces a plurality of parallelly disposed grooves and disposed at an acute angle to said egress; said parallel grooves on one of said plates are disposed in crossing relationship to said parallel grooves on the other of said plates.
Claim 6
Independent Claim
156 words
An apparatus comprising: a one piece aperture plate shaped substantially triangular having an aperture disposed at one corner thereof; an one piece cover plate shaped substantially similar to said aperture plate and disposed in back to back relationship to said aperture plate to form a distending outwardly flaring passageway having an elongated egress disposed opposite said aperture on said plate; said descending outwardly flaring passageway becomes thinner as the passageway becomes removed from said aperture in said aperture plate; a releasing ridge being formed integral on each of said plates and extending into said flaring passageway and disposed near said egress and opposite each other; each of said plates having formed on their respective facing surfaces a plurality of parallely disposed straight grooves which are disposed at an acute angle to said egress; said parallel grooves on one of said plates being disposed in crossing relationship to the parallel grooves on the other of said plates.
