Abstract
<PICT:0727646/III/1> <PICT:0727646/III/2> The viscosity and water-solubility of plastic materials containing a crystalline phase (e.g. soaps and synthetic detergents such as sulphated monoglycerides) is increased by forcing the solid plastic material through a shearing and compacting zone comprising a pair of walls substantially uniformly spaced apart a distance of the order of not more than one sixty-fourth of an inch, the shearing and compacting being caused by relative movement of the walls in a direction substantially parallel to their length. The pressure applied to the plastic material entering the shearing and compacting zone is sufficient to ensure that the material completely fills the zone, while the temperature of the material passing through the zone is maintained below its melting point. In Figs. 1 and 3, a metal band 3 is mounted on driven wheels 1 and 2 and passes through metal die slot members 7 and 8. Plastic material enters die slot members 7 and 8 through plodder-type feeding devices 6 and leaves via hoppers 13 and 14. Die slot members 7 and 8 are provided with a slot 21 through which the band 3 passes, the clearance between the band and the walls of the slot being not more than about one sixty-fourth of an inch across the breadth of the band. Slot 21 is provided with a labyrinth seal 23 at its entrance, in order to prevent escape of plastic material which is introduced into p chamber 20. Plastic material adhering to band 3 as it leaves slot 21 is removed by knives 35 in the form of flakes or chips. Slot 21 may be provided with expansion chambers 29, and also stripper chambers 30 wherein the plastic material is stripped from band 3 by means of knives 31 and then allowed to recoat the band again. Gases such as air may be introduced into stripper chambers 30 through line 15, for example in the production of aerated soap or synthetic detergent, particularly floating soap. Alternatively, line 15 may be connected to a source of vacuum in order to remove gases from the plastic material. The die slot members 7 and 8 may incorporate cooling chambers and band 3 may also be cooled. Soap flakes or chips obtained by the process may be compacted into tablets, or used to prepare shaving creams or powders.
