Description: -'/ - "UNIVERSAL MACHINE FOR SOAP EXTRUSION" The present invention concerns machines for the extrusion of soap- Many machines of this type are already known; each of them allow however only the making of one soap or of some types of soap having all a single basic characteristics. Ve know instead that toilet items, such as soap cakes, must be frequently changed in their exterior look. One of the most requested variation is the colouring. These pieces of soaps with one or more colours can be obtained by using the pastes of two soaps, or by adding liquids - 2 - to a basic paste or eventually by following both the mentioned procedures. For each of these variations it has been necessary till now to have a different machine or to substitute important parts of a given machine. This entails considerable work and 5. long stopping periods for the machine. The aim of this new device is to have a universal machine which can produce pieces of soap of substantially different type using one single machine which can be adapted quickly to each specific use. 10. The above mentioned object has been reached by a package unit in which it has been deviced in succession an extruder for the basic paste fitted at its exit with a first connection, an operating device for a rotor comprising a power take-off, the rotor being fitted upstream with a second connection mating with 15- the first connection, and downstream with a third connection, a rotor in one piece with a shaft which can be engaged in the power take-off, a filtering place, an extrusion head capable to contain this rotor and having a fourth connection mating with the third connection, the third and fourth connections compris- 20. ing between them the filtering place. Preferably the filtering plate is fitted with injectors for a coloured liquid caning from a metering device. An extruder for auxiliary coloured soap can also be foreseen; this is fitte"d at the exit with a double connection, the one 25. upstream to be connected with the hird connection, while the one downstream to be connected with the fourth connection. In this case, a rotor with an extended shaft is also foreseen so that it can be inserted in the power take-off of the operating device. A further improvement provides for the rotor to rotate both in the same direction and in the opposite direction of the main 5. extruder. In this case the filtering perforated plate can have or not have the nozzles for the injection of the coloured liquid. The invention will be now better illustrated by the examples carried out and shown in the enclosed drawings, in which: 10. Fig. 1 is a schematic view of the various types of installa¬ tions; Fig. 2 is an exploded view of a first installation indicated by A in Fig. 1 ; Fig. 3 is an exploded view of a second installation indicated 1 . with B in fig. 1 ; Fig. 4 is an exploded view of a third installation indicated by C in fig. 1. Referring first to Fig. 1 we note that the base installation includes the following package units: an extruder 10, an 20. operating device 20, a perforated filtering plate 40 and an extrusion head 50. Preferably the plate 40 is fitted with injectors 41 for the injection of coloured liquids, as shown in embodiment A of Fig. 1. This installation has been shown with more details in Fig. 2. This shows extruder 10 coupled to the 25. operating device 20 which is in turn connected to an extrusion head 50, comprising between them a perforated plate 40 having nozzles 41 for the injection of coloured liquids through the metering device 43 which lets the pressed liquid in by the tubes 42. Donwstream the filtering plate 40, the extrusion head 50 is 5- conceived to receive a rotor 60 having a short shaft 62. Extruder 10 is conceived at the exit with a connection 11 that can be coupled to the operating device 20. This is conceived with a package unit which connects downstream to the extruder. Unit 25 includes upstream a second connection 21 which mates 10. with connection 11. The operating device has also a third connection 22 which can be coupled to a fourth connection 52 provided in extrusion head 50, comprising between them the perforated plate 40. Operating device 20 is provided with a power take-off 23 which 1 - is devised to receive terminal 63 of the shaft 62 integral with blades 64 of rotor 60. Between these last two connections, 22 and 52 respectively, is inserted the perforated plate 40. Another installation (type B of Fig. 1 ) is shown in Fig. 3. Also here we have an extruder 10 having a first connection 11, an 20. operating device 20 provided with a second and third connection, respectively 21 and 22, as well as a power take-off 23. At this point the terminal 35 of an auxiliary extruder 30 is inserted as a further package unit which is provided with two further connections, the fifth connection 32 placed upstream and 25. conceived to mate with the third connection 22 and a sixth connection 33 placed downstream and mating with the fourth connection 52 of the extrusion head 50. Also in this case the perforated plate 40 is foreseen, this time however without injectors for the liquid. Fig. 4 shows -aiibodiment C of Fig. 1 which is similar to Fig. 3 but where the perforated plate 40 is provided with injectors 41 , - a.lso fed by a metering device 43 is through tubes 42. In both cases of Fig. 3 and 4 the rotor 60 comprising blades 64 has a shaft 61 which is longer than shaft 62 used in the embodiment of Fig. 2, but it is also fitted with an attachment 63 mating with the power tale-off 23 of the operating device 20. 10. As it will be noted the shifting from an installation to the other can be immediate as the connections allow a swi t change of the pieces.
