Abstract
Abstract A pretzel making method wherein dough is extruded and the extrusion is rotated about an eccentric axis into a spiral configuration for baking. The extruded dough is gravitationally passed to a conveyor belt. The vertical distance that the dough downwardly passes through is varied to change the wound spiral to a selected pitch.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
91 words
In the method of manufacturing pretzels, the steps which comprise: extruding pretzel dough to form at least one dough strand, rotating said dough strand during extrusion about an eccentric axis to spirally wind the dough strand, gravitationally passing the dough strand downwardly during said rotation through a vertical distance from the point of final extrusion onto a conveyor belt, varying said vertical distance to change the wound spiral to a selected spiral pitch, and conveying away on the conveyor belt the spirally wound dough strand of the selected pitch for baking.
