Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
184 words
A machine for producing a food product comprising a double nozzle extruder machine having a central nozzle arranged within a surrounding nozzle; a first hopper arranged to supply a food material to the central nozzle; a second hopper arranged to supply a moldable food material to the surrounding nozzle; means for continuously transfering moldable material from said hoppers for extrusion through said nozzles; means for intermittently stopping extrusion of material through said central nozzle, said means including a plunger arranged to serve as a stopper in the central nozzle, and means for intermittently co-axially inserting said plunger into and for withdrawing said plunger from said central nozzle; means for conveYing material extruded from said nozzles; means for intermittently transversely cutting through the material extruded from said surrounding nozzle; and means for synchronizing the extrusion of moldable material through said central nozzle and the cutting of said extruded ribbon of moldable material such that the moldable material extruded through said surrounding nozzle is cut between intermittent extrusions from said central nozzle whereby said intermittent extrusions are entirely surrounded by material extruded from the surrounding nozzle.
Claim 2
Dependent Claim
184 words
A machine for producing a food product comprising a double nozzle extruder machine having a central nozzle arranged within a surrounding nozzle; a first hopper arranged to supply a food material to the central nozzle; a second hopper arranged to supply a moldable food material to the surrounding nozzle; means for continuously transfering moldable material from said hoppers for extrusion through said nozzles; means for intermittently stopping extrusion of material through said central nozzle, said means including a plunger arranged to serve as a stopper in the central nozzle, and means for intermittently co-axially inserting said plunger into and for withdrawing said plunger from said central nozzle; means for conveYing material extruded from said nozzles; means for intermittently transversely cutting through the material extruded from said surrounding nozzle; and means for synchronizing the extrusion of moldable material through said central nozzle and the cutting of said extruded ribbon of moldable material such that the moldable material extruded through said surrounding nozzle is cut between intermittent extrusions from said central nozzle whereby said intermittent extrusions are entirely surrounded by material extruded from the surrounding nozzle.
Claim 3
Dependent Claim
71 words
A machine as in claim 1, wherein the means for intermittently inserting said plunger into and for withdrawing said plunger from said central nozzle includes a shaft connected to said plunger, arranged to slide said plunger into said central nozzle; and a pneumatic cylinder having a rod therein that is coupled to said shaft and is arranged to reciprocate said shaft in response to air pressure supplied thereto and exhausted therefrom.
Claim 4
Dependent Claim
14 words
A machine as in claim 1, further including means for continuously rotating said plunger.
Claim 5
Dependent Claim
17 words
A machine as in claim 1, wherein the outer surface of the plunger is made of polytetraflourethylene.
Claim 6
Dependent Claim
113 words
A machine as in claim 1, wherein the means for conveying material extruded from the nozzles comprises an endless conveyor belt and the means for cutting the moldable material extruded through the surrounding nozzle includes cutting wheel having circular sides with their peripherys resting on the conveyor belt such that the cutting wheel is revolved by movement of said conveyor belt; and a plurality of cutting blades radiating from the center of the cutting wheel, between the sides thereof and extending outwardly to the outer circumference of said wheel such that as said conveyor belt moves the extruded material between the sides of the cutting wheel the blades cut through the said material.
Claim 7
Dependent Claim
92 words
A machine as in claim 5, wherein the means for synchronizing the extrusion of moldable material through said central nozzle and the cutting of said extruded ribbon of moldable material includes spaced notches formed at the outer circumference of one side of said cutting wheel; a follower; means biasing the follower against the periphery of the said one side; means generating an electrical signal as the follower moves into each notch and means responsive to said electrical signal to operate the means for intermittently stopping extrusion of material through the central nozzle.
Claim 8
Dependent Claim
80 words
A machine as in claim 6, wherein the means for continuously transfering moldable material from said hoppers comprises an auger in each hopper and motor means to drive each auger; and the means for intermittently stopping extrusion of the material through the central nozzle includes clutch means interconnecting the motor means arranged to drive said auger and means responsive to the electrical signal to operate said clutch to drivingly disengage the motor means and the auger in the first hopper.
