Abstract
Abstract Process and apparatus for making a novel food product by extruding a plurality of separate plastic strands of food material through a stationary die to produce a composite sticklike product wherein the strands are in an overlaid helical or "twisted" configuration. The die includes separate individually converging straight bores that conjointly converge toward a common axis but are skewed or offset about said axis in the same direction so as to impart a helical configuration to the strand components of the composite extrudate. The strands may, for example, be of contrasting colors to impart a pleasant aesthetic affect to the final product.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
A process for producing substantially cylindrical sticks of extrudate having alternating helical stripes of a plurality of contrasting colors comprising the steps of feeding each color in a separate stream with streams of contrasting colors alternating with one another in mutually parallel relationship, and conjointly extruding the streams into cylindrical form in a stationary die by progressively bunching said streams along straight lines such that said streams converge substantially toward a common axis and are skewed about said axis in the same rotational direction, until each stream slightly overlaps and is merged with the adjacent streams.
Claim 2
Dependent Claim
96 words
A process for producing substantially cylindrical sticks of extrudate having alternating helical stripes of a plurality of contrasting colors comprising the steps of feeding each color in a separate stream with streams of contrasting colors alternating with one another in mutually parallel relationship, and conjointly extruding the streams into cylindrical form in a stationary die by progressively bunching said streams along straight lines such that said streams converge substantially toward a common axis and are skewed about said axis in the same rotational direction, until each stream slightly overlaps and is merged with the adjacent streams.
Claim 3
Dependent Claim
92 words
In a process for producing substantially cylindrical sticks of overlaid laminates in helical array, comprising the steps of passing the laminae through respective bores in a stationary die along substantially parallel discrete paths at the entrance of said die and into a single path at the exit of said die, and within said die, converging the laminae toward one another and at the same time skewing the laminae in the same direction about a common axis for imparting a twisted configuration to the laminae as the laminate is extruded from the die.
Claim 4
Dependent Claim
92 words
In a process for producing substantially cylindrical sticks of overlaid laminates in helical array, comprising the steps of passing the laminae through respective bores in a stationary die along substantially parallel discrete paths at the entrance of said die and into a single path at the exit of said die, and within said die, converging the laminae toward one another and at the same time skewing the laminae in the same direction about a common axis for imparting a twisted configuration to the laminae as the laminate is extruded from the die.
Claim 5
Dependent Claim
60 words
In a process for producing an extrudate having a plurality of overlaid laminae arranged in helical array, the steps of extruding the laminae in respective paths along substantially parallel discrete paths, and converging said laminae toward one another while skewing each laminate in the same direction about an axis for imparting a helical configuration thereto with respect to other laminate.
Claim 6
Dependent Claim
60 words
In a process for producing an extrudate having a plurality of overlaid laminae arranged in helical array, the steps of extruding the laminae in respective paths along substantially parallel discrete paths, and converging said laminae toward one another while skewing each laminate in the same direction about an axis for imparting a helical configuration thereto with respect to other laminate.
