Abstract
Abstract Striped, multi-colored soap bars can be produced by introducing coloring matter into the soap mass while the soap mass is passing through the ducts of an extruder plate in a soap plodder. The apparatus for producing such a bar comprises a conventional soap plodder with a modified extruder plate having a plurality of injector tubes which permit the flow of the coloring matter into the ducts of the extruder plate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
In a method for producing a multi-colored detergent bar which includes pressing and passing a detergent material in a circular motion through a final plodding stage in which said material is passed forwardly through a cylindrical channel in said plodding stage by screw action to knead said material, then passing said material through a plurality of separate ducts contained in a plate between said plodding area and a conical area and into said conical area, and compacting said material in said conical area, the improvement which comprises introducing coloring matter in a confined stream into said material from an injection tube and directing said stream from a stationary orifice in said tube with said tube being located within one of said ducts in the direction in which the detergent material is being passed through said Duct, the area of said confined stream being small as compared to the area of said duct, whereby to produce an extruded bar having a stripe therein.
Claim 2
Dependent Claim
162 words

Claim 3
Dependent Claim
38 words
A method as set forth in claim 1 in which said coloring matter is introduced separately into a plurality of said ducts whereby there is produced an etruded bar of said material having a plurality of stripes therein.
Claim 4
Dependent Claim
10 words
The method of claim 1 wherein said detergent is soap.
Claim 5
Dependent Claim
138 words
In apparatus for producing a multi-colored detergent bar comprising a final stage plodder cylindrical in form containing a screw for kneading detergent material and passing the same longitudinally through said plodder, a nose cone located forwardly of said screw for compacting said material radially of the axis of said cone, a plate located between said screw and said cone having ducts therein providing channels through which said material may pass in separate channels, a tube extending into one of said ducts, said tube being in fixed position with respect to said duct and containing an orifice within said duct which is aligned with said duct whereby coloring matter passed through said tube and out of said tube through said orifice is directed into said channel in the direction in which said material is being passed through said duct.
Claim 6
Dependent Claim
138 words
In apparatus for producing a multi-colored detergent bar comprising a final stage plodder cylindrical in form containing a screw for kneading detergent material and passing the same longitudinally through said plodder, a nose cone located forwardly of said screw for compacting said material radially of the axis of said cone, a plate located between said screw and said cone having ducts therein providing channels through which said material may pass in separate channels, a tube extending into one of said ducts, said tube being in fixed position with respect to said duct and containing an orifice within said duct which is aligned with said duct whereby coloring matter passed through said tube and out of said tube through said orifice is directed into said channel in the direction in which said material is being passed through said duct.
Claim 7
Dependent Claim
31 words
Apparatus as set forth in claim 4 in which said plate includes a ring disposed between said cone and said plodder and wherein said tube is carried radially within said ring.
Claim 8
Dependent Claim
29 words
Apparatus as set forth in claim 4 including a bracing member extending within said duct and connected to said tube for positioning said tube with respect to said duct.
