Abstract
Abstract A dough forming and extruding machine having upper and lower pairs of staging and feeding rolls coordinated by driving mechanisms operating the rolls at similar speed wherein the staging rolls, being of smaller diameter, result in higher surface speed of the feed rolls whereby linear travel of the feed rolls is greater, thus increasing pressure of the dough against the extrusion openings.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
A dough forming and extruding machine including a hopper and extrusion means, a pair of feed rolls mounted in said hopper, a pair of staging rolls mounted in vertically associated relation respectively with said feed rolls, means for driving said staging and feed rolls, means providing greater surface speed of said feed rolls than that of said staging rolls, the axes of said staging rolls being disposed on the same vertical center lines as the axes of said underlying feed rolls, and said staging rolls being so spaced above said feed rolls as to wipe past the feed rolls and maintain a uniform amount of dough on said feed rolls.
Claim 2
Dependent Claim
110 words
A dough forming and extruding machine including a hopper and extrusion means, a pair of feed rolls mounted in said hopper, a pair of staging rolls mounted in vertically associated relation respectively with said feed rolls, means for driving said staging and feed rolls, means providing greater surface speed of said feed rolls than that of said staging rolls, the axes of said staging rolls being disposed on the same vertical center lines as the axes of said underlying feed rolls, and said staging rolls being so spaced above said feed rolls as to wipe past the feed rolls and maintain a uniform amount of dough on said feed rolls.
Claim 3
Dependent Claim
27 words
A dough forming and extruding machine as set forth in claim 1 wherein said staging rolls are spaced apart laterally a greater distance than said feed rolls.
Claim 4
Dependent Claim
41 words
A dough forming and extruding machine as set forth in claim 1 wherein said driving means includes sprocket means mounted on the respective staging and feed rolls and chain means connecting said sprocket means, and motor means actuating said chain means.
