Abstract
Abstract of the Disclosure The invention provides apparatus for the continuous production of striped soap comprising means for providing an axially moving column of a first soap, means for providing and imbedding a plurality of circumferentially spaced longitudinally extending streams of a different soap or soaps within and along the surface of said column to provide a moving composite soap mass, means for subjecting said moving soap mass to substantially uniform radial compression and means for subsequently extruding said mass in substantially uniform cross section.
Description
This invention relates to apparatus for the manufacture of striped soap, and is di~ided out of our Canadian Patent Application Serial No.
201,916, filed June 12, 1973, which relates to a method for the manufacture of striped soap.
Apparatus and methods for the manufacture of striped soap have been proposedJ as for example in the patents to W.A. Kelley et al, Nos. 3,268,970;
3,294,692; and 3,398,219.
The present invention distinguishes over known prior art in that incorporation or setting of different soaps into a composite mass already embodying the desired surface striping takes place in a region wherein the mass is undergoing uniform radial compression, and this has been found to be advantageous in the production of soap bars of superior appearance and resis-tance to separation of the different soaps during useful life. The patent to Garvey et al No. 2,296,842 discloses the extrusion of indicia forming soap streams within a main body of soap being forced through a plodder cone, but this does not produce striped soap.
The invention further includes the advantage that the plastic soaps being incorporated into the composite mass being radially compressed are of substantially the same beta phase content.
The invention provides, in one aspect, apparatus for the continuous production of striped soap comprising means for providing an axially moving column of a first soap, means for providing and imbedding a plurality of circumferentially spaced longitudinally extending streams of a different soap or soaps within and along the surface of said column to provide a moving composite soap mass, means for subjecting said moving soap mass to substan-tially uniform radial compression to set the imbedded different soaps in the soap mass and means for subsequently extruding said mass in substantially uniform cross section.
In another aspect the invention provides apparatus for the continuous production of striped soap comprlsin~ means deining a conical pas-sage, means for feeding a solid column of a first soap in plastic condition 11~)~i5 under pressure toward the larger end of said passage, means in the path of said column providing a plurality of circumferentially spaced downstream facing openings for depositing and imbedding streams of a different soap or soaps in plastic condition within and along the periphery of said column to form a slidably moving composite soap mass within said passage, said mass being substantially uniformly radially compressed during movement along said passage, and means at the smaller end of said passage whereby said mass is extruded in substantially uniform cross section.
A feature of the invention is a novel manifold arrangement mounted on the plodder cone and having internal projections extending into the cone for discharging a second soap or soaps into a first soap column being forced along the cone toward an extrusion nozzle, as well as arrangements for provid-ing substantially uniform soap pressure in the annular manifold space.
The invention is further illustrated with reference to the accompanying drawings showing, by way of example, embodiments of the inven-tion, in which:

Figure l shows mainly diagrammatically a conventional type soap plodder : .$
11 wherein milled soap is compressed and compacted by a rotating worm 12 and forced through a terminal converging cone 13 from which it is discharged ~ through extrusion nozzle 14 as a continuous bar. The extrusion nozzle imparts . the , . ..
.
.~ , ~~
. ~ . .
107~)465 desired shape and cross section to ;he extruding bar, usually rectangular or circular. Except as will appear this plodder construction may be for example similar to that disclosed in Compa et al. Patent No. 3,485,905.
Referring to Figs. 1 and 2, the cone 13 intermediate its ends is surrounded by a hollow annular manifold member 15 that is fixed to the cone. Member 15 is formed with a circum-ferentially spaced plurality of radially inwardly extending closed rear and side projections 16 that extend fluid tight through apertures 17 in the wall of cone 13 and are formed with fron~ discharge openings 18 that open toward extrusion nozzle 14. As shown in Figure 3 the radially outer edges of openings 18 are preferably flush with the smooth inner surface 24 of the cone. Member 15 may be made in two semi-circular parts secured together along a diametral plane.
A second source of soap is indicated at 21 in Figure 1.
This may comprise another plodder assembly or any device wherein soap is worked under controllod pressure and moisture content conditions and discharged as a continuous column through a conduit 22 which (Figure 2) is connected to discharge into the annular space 23 within manifold 15.
In operation a continuous solid column of the first or main soap in plastic condition is forced by the worm 12 through cone 13. This column flows around the closed rear and side walls of projections 16, thereby effectively forming outwardly open relatively deep longitudinal furrows open out-wardly at the periphery of the first soap column. At the same time a plurality of streams of the second soap in plastic condition 1~704~
are continuously discharged downstream through nozzles 18 into those furrows and become embedded in the moving column of the first soap, thereby effectively depositing and imbedding longitu-dinal stripes of the second soap upon and along the first soap column. ~he soaps are preferably of different color.
During the time that the second soap streams are being incorporated with the first soap column, the entire composite mass is slidably supported by the smooth conical inner surface 24 of cone 13 and is uniformly radially compressed up to the point it is extruded at 14. Figure S diagrammatically illustrates a cross section of the composite mass moving along the cone downstream of manifold 15. The radially outer surface of each second soap stream slides along the cone wall 24 while the unsupported radially inner surface of each second soap stream seeks the bottom of the furrow in the main soap column.
Since the radially outer surface of each second soap stream is in sliding contact with cone surface 24 the reducing cone diameter results in the second soap streams being positively forced radially deeper into their respective furrows. At the same time the second soap streams are being laterally compressed within the furrow sides or for a time within converging lateral extensions of the manifold openings as will appear in Figures 8 and 9. As a result extremely good surface engagement is ensured between the main soap column and the sides and inner ends of each second soap stream while the outer surface of each second soap stream remains in contact with the smooth cone surface at the same level as the adjacent first soap column periphery.
1.070465 It has therefore been found that by locating the rcgion of incorporation of the stripe forming streams into the main soap column so that both during incorporation and for an appreciable period thereafter the composite mass is subjected to uniform radial compression a better surface bond is attained between the first soap column and the stripe forming streams of the second soap.
The compression brings the stream and furrow surfaces into full surface contact so that there are no voids, and the contacting surfaces are better adhesively bonded.
Preferably the streams of second soap entering the furrows of the first soap move at about the same linear velocity as the first soap column, and the two soaps have about the same plasticity.
It has been found particularly advantageous if the first and second soaps have the same beta phase content, as this combination results in better surface bonding of the stripes with the central soap column.
The radial depth of the longitudinal stripes and their spacing width and shape may be determined by the number~
shape and size of projections 16 and openings 18.
It has been noted that where space 23 is of uniform size all around the cone and there is only one second soap inlet as shown in ~igure 1, there may be sufficient drop in pressure in the second soap that the second soap ctreams exiting from the openings 18 that are more remote from the connection fr0m the space 23 to conduit 22 may not contain 1~7t)4~5 the same a~ount of soap as those closer to conduit 22, thus resulting in some non-uniformity in the striping appearance. This may be advantageous for certain purposes, but for better uniformity a second conduit from source 21 may be connected to space 23, for example about 180 from the point shown in Figure 1, with the result that there will be a more equal pressure distribution along the second soap in space 23.
Figures 7 and 8 illustrate another mode of combining the soaps at the manifold. Here the manifold 31 is integrally formed upon an intermediate part of cone 13 and, as shown in Figure 7 has a tubular second soap intake conduit 32 connected to one side thereof while the opposite closed side 33 is eccentric to the cone axis and defines an enlarged manifold space 34 at 180 from the intake. At its juncture with the manifold wall conduit 32 is faired to provide smooth transition surfaces 35 and, between the transition surfaces and at the inner end of conduit 32 is centrally disposed a soap divider plate 36 or teardrop or like streamline contour to oppositely divert opposite sides of the soap column of conduit 32 of flow around opposite sides of the manifold toward space 34. As in the other embodiments conduit 32 is connected to provide a continuous supply of the second, usually colored soap.
Manifold 31 is formed similarly to the earlier embodiment, with circumferentially spaced hollow projections 36 radially outwardly open to the interior of the manifold as indicated at 37 in Figure 7 and projecting as nozzles into the cone in the path of the column of the first soap where they are open downstream as indicated at 38 to discharge into the first soap which is passing centrally of the cone 10704t;5 and between the nozzles. The comblnation of the divider plate and the eccentric space 34 aids in providing substantially equal supply of second soap to all nozzles.
Also as shown in Fig. 8 wherein flow of the first soap ls indicated in solid line arrows and the second soap flow in dotted line arrows there is preferably provided at the end of cone 13 prior to extrusion an annular internal surface 39 that is concave in the upstream direction and effects a smooth progresslve change in the reduction of the composite soap column prior to extruslon. Preferably surface 39 is surrounded by water ~ackets 41 for cooling the extruding soap surfaces.
Also shown in Fig. 8 the side walls of each of the proJectlons 36 are longitudinally extended interiorly of 1~ the cone to form lateral guides and retainers 42 and 43 for the soap streams issuing from openings 38. These guides are dlsposed on opposite sides of the furrows in the main soap column and may extend~almost to surface 39 if desired. mus each second soap stream emerging from the manifold is for a time positively contained and guided by the lateral extensions 42 and 43 while being free at their upper and lower surfaces to engage the cone wall and the bottom of a furrow in the main soap column respectively.

A second source of soap is indicated at 21 in Figure 1.
This may comprise another plodder assembly or any device wherein soap is worked under controllod pressure and moisture content conditions and discharged as a continuous column through a conduit 22 which (Figure 2) is connected to discharge into the annular space 23 within manifold 15.

~ollowing extrusion the soap column 40 issuing
2~ from nozzle may be cut into bar sizes and compressed in the direction of the grain of extrusion to final condition.
The manifold through wh~ch the second soap streams are introduced lnto the main soap at the cone may be a separate surrounding member as illustrated in Figs. 1-3, it may be formed integral with the cone wall as illustrated in Figure 8, or it may be an intermediate separate part secured between the end .; of the plodder barrel and the cone as illustrated in Figure 9.
