Definitions

  • This invention relates to the. manufacture of milled toilet soap cakes and more particularly to the production of designs in such cakes.
  • this tube being of such dimensions that the rods may pass freely through it and having an open front end which lies in the plodder nozzle between the front end oi the plodder feed screw and-the restricted discharge opening of the plodder.
  • Each rod is pushed through the tube until its front end projects just far enough beyond the front end of the tube to be gripped by the body soap which is travelling through the plodder past the front end of the tube.
  • FlFig. 2 is a cross-section on the line 220f
  • Fig. 3 is a partial cross-section on theline 3-3 as of Fig. 7,
  • Fig. 4 is a cross-section on the line 4-4 of Fig. 1
  • Fig. 5 is a cross-section on the line 5-5'of Fig. 1.
  • Fig. 6 is a face view of a completed cake of soap made in accordance with the invention
  • Fig. '7 is a diagrammatic view of the apparatus shown in Fig. 1.
  • the apparatus a plodder A for making the of the design, and a plodder B for making the completed cakes including the design.
  • the plodder A may be of any ordinary type and, as shown, includes a cylinder l fed from a hopper H and containing a'feed screw I2. Soap is discharged from the cylinder III by the feed screw I2 through the usual strainer unit l3'into the plodder nozzle M, where it is compressed. Attached to the end of the nozzle I4 is a die
  • the desired design in the as shown includes two plodders, soap rods in the form form of a cross which is shown in process of formation in Fig. 2.
  • a continuous rod having the cross-section of the cross issues from the discharge end of the plodder A and is received on any suitable support, matically shown in the drawing. It is cut into shorter rods [8 of appropriate lengths to fit the support by a cutter H of any suitable conventional type, such aathat consisting of a circular frame with a wire stretched across it.
  • the tray may be adapted to support a number of rods l8 side by side, as shown in Figs. 3 and 7, and is provided with a number of parallel slots IQ for this purpose, the rods l8 being, as shown in Fig. 3, easily slidable in these slots.
  • the plodder 13 like the plodder A, has a cylinder 20 fed with soap from a hopper 22 and containing a feed screw 2
  • the feed screw carries soap from the rear 23 of the cylinder towards the tapered nozzle 24, which terminates at its forward end in a restricted opening 25 defined by a forming plate 25a.
  • has a hollow shaft 25 .within which is supported on bearings 21 a stationary hollow tube 28 designed to permit a rod l8 to pass freely through it.
  • Within the tube is a removable support 29 shaped like a section of the tray IS with a longitudinal slot 30 like the slots i9 and adapted to support but allow free longitudinal movement of a rod l8.
  • the tube 28 is' open and accessible at the rear 23 of the plodder and extends forward beyond the feed screw 2
  • the forward portion 32 of the tube is of appreciable length and preferably has thin walls. As can be seen from Fig. 5, it has the indented cross-sectional shape both internally and externally of the desired design, and its internal cross-sectional dimensions are just slightly greater than the cross-sectional dimensions of the desired design, so that a rod
  • a perforated plate 35 such as a tray l5 diagramvanced through the nozzle 24 away in Fig. 1) with which may be associated a strainer screen 36.
  • This plate whichis fully discussed in copending application Serial No. 538,296, filed June 1, 1944, is, briefly, to break up the plastic soap fed by the .feed screw 2
  • the tray I6 carrying rods l8 of the desired cross-sectional shape e. g., a cross
  • the rod I8 is then pushed forward into the tube 28.
  • Mechanical means might be devised for this purpose but the operation can quite satisfactorily be carried out manually.
  • the rod is preferably longer than the overall length of the tube 28 and is pushed forward in that tube until it front end just projects from the forward end 3
  • This plastic soap is fed progressively by the feed screw through the nozzle 24, where it is subject to radial compression exerted substantially transversely of its axis of travel and gradually increas ing owing to the taper of the nozzle, as the opening 25 is approached.
  • the soap is thus strongly compressed aroundthe front portion 32 of the tube 28. Since this t'ube'has'the external crosssectional shape of the rod I8, the plastic soap assing over it is shaped internally in accordance with the external shape of the rod, the opening in the soap produced by the presence of the portion 32 being simply of somewhat greater dimensions than the rod l8. As the plastic soap passes the forward end 3
  • the rod As the advancing movement of the soap continues towards the opening 25 the rod, being perfectly free to move longitudinally, is drawn along with the soap completely surrounded by the latter. As successive portions of the rod are exposed by reason of this longitudinal motion, they are in turn surrounded and gripped by the plastic 'soap travelling past the forward end 3
  • the rate of movement of the rods i8 through the plodder B depends solely on the rate of movement of the plastic soap which is to surround them, i.e., of the soap which will form the body of the final cake. If, for any reason, the rate of movement of the body soap increases, the rods are simply pulled through a little faster. If it decreases they are pulled through more slowly and, if for some reason the plodder B stops, then the movement of the rods it through it stops also. There is, thus, no problem of synchronizing the operation of two plodders. The rate of operation of the plodder A is in no way related to the rate of operation of the plodder B.
  • the trays iii are simply one suitable means of storing the rods which are made by the plodder A.
  • That plodder could quite well operate to make a large number of rods which might then be stored in any appropriate way and subsequently used in the plodder B at a time when the plodder A might not be operating at all.
  • the invention thus allows the plodder B to operate with exactly the same flexibility as if it were making ordinary soap without a design extending therethrough.
  • the shaped forward portion 82 of the tube 23 is particularly necessary for designs of indented cross-sectional shape such, for instance. as letters of the alphabet and the cross shown in the drawings. These are referred to as being of indented cross-sectional shape, because they present indentations on their external surfaces.
  • the cross may be regarded as a square which is, indented at each of its four corners.
  • the rods will normally be of soapof diflferent characteristics from those of the plastic soap, generally of a different colour from the latter.
  • the rods need not necessarily be of soap. They might be of some other material adapted to dissolve in water at substantially the same rate as the soap, if that were considered commerciaily desirable.
  • the method of producing soap cakes with a continuous design extending axially therethrough which comprises supporting a preformed rod of soap having the cross sectional shape of the desired design for free longitudinal movement with its front end exposed in a zonein which increasing radial compression is adapted to be exerted substantially transversely to the longitudinal axis of said rod and which terminates at a restricted opening, s.
  • . 7 formed rod of .soap having the cross sectional shape of the desired design for free longitudinal movement with its front end exposed in a zone in which radial compression isadapted to be exerted substantially transversely to the longitudinal axis of said rod, forming strips of plastic soap the indented cross-sectional shape.
  • a preformed soap rod having the crosssectional dimensions of the desired design may having different characteristics from those of the soap of said rod, coiling said strips helically,
  • Apparatus for producing a soap bar with a continuous design of indented cross-section extending axially therethrough which comprises a plodder having a restricted opening at the forward end thereof and means for feeding plastic soap to said opening and extruding it therefrom, a tube extending into the plodder from the rear end thereof towards the forward end and designed to permit a preformed soap rod having the cross-sectional dimensions of the desired design to pass freely therethrough, said tube being open and accessible at the rear of the plodder and terminating at its forward end, between said opening and the forward end of said feeding means, in a portion of appreciable length having just pass freely through said portion.
  • Apparatus for producing a soap bar with a continuous design extending axially therethrough which comprises a plodder having a restricted opening at the forward end thereof and a feed screw for feeding plastic soap to said opening and extruding it therefrom, a perforated plate mounted between two-adjacent flights of said screw near the forward end thereof, said plate extending from one of said flights to the other and extending from the axis of'said screw to substantially the periphery of said flights, whereby all soap fed by said screw is forced to pass through said plate, a tube extending into the plodder from the rear end thereof along the axis of the feed screw and designed to permit a preformed soap rod having the cross-sectional dimensions of. the desired design to pass freely therethrough, said tube being open and accessible at the rear of the plodder and terminating at its forward end close to'said restricted opening
