Abstract

Firmly packaged foam material is produced without contacting the outer air by (a) stirring a crystalloid in liquid or slurried condition with the foam components (b) supplying the homogeneous mixture to a cylinder or chamber with a closed end, (c) introducing a gas, (d) intimately mixing the air by vortex flow with the mixture so that it contains small gas bubbles, both the gas and the homogeneous mixture being introduced into the chamber in the vicinity of its closed end, (e) pressing the foamed mass out through the open end of the chamber, into a long, thin walled flexible tube, which becomes slowly filled with the foamed mass while screening the mixture from air, (f) clamping the tube at predetermined distances, and heat sealing and cutting the tube to form foam packages or blocks, in which the original pressure of the injected gas is present, (g) optionally converting the packages into a suitable shape, and (h) cooling the packages in a chamber, in which the foam material crystallises and solidifies.
