ABSTRACT:
Device and procedure for safely conveying and handling a cellulose solution suitable for manufacturing solvent-spun cellulose molded parts, in particular for manufacturing fibers, films and membranes, in devices for conveying and handling the spinnable cellulose solution, provided with a tempering device, wherein the temperature in the tempering system is reduced once the temperature in the cellulose solution has exceeded at least a first limiting temperature, as a result of which the temperature of the spinning solution drops and the reaction mixture is prevented from passing through. A procedure and device with two switching stages is also disclosed.
