Abstract
En fremgangsmåte for fremstilling av en suspensjon av cellulose i et flyt- ende, vannholdig tertiært aminoksid, idet oppdelt cellulose blandes med det flytende, vannholdige tertiære amin- oksid, hvor fremgangsmåten består i at A) den oppdelte cellulose bringes i kontakt med det flytende, vannholdige tertiære aminoksid og det dannes en første blanding, og B) denne første blanding utbres sjiktliknende på en flate og transporteres over denne flate under intensiv blanding inntil det dannes en homogen suspensjon som tas bort fra flaten, idet C) tiltakene A) og B) utføres kontinuerlig.
