Abstract: A device for the continuous production of a strand of foamed material comprising a vessel to which a foamable reactant material is continuously supplied and from which said material continuously issues over a weir whose height is adjustable. The material passing over said weir becomes supported on a foaming track whose constituent parts are adjustable as regards length and inclination to suit the foaming characteristics of said material. Said foaming track is adjustable also relative to said weir so as to be kept close thereto and is also adjustable relative to a curing track.
