Abstract

Anordning for tilforming av et ved øket temperatur tilformbart bånd, særlig et bånd av termoplastisk plast, ved løp over overflaten til en roterende trommel 1 som oppvarmes og/eller kjøles i på forhånd bestemte, stasjonære områder 10, 11. For å redusere energitapene som følge av varme- og kjøleveksling, er den tynnveggede trommel opplagret på et bærelegeme 5, som i de nevnte områder er oppvarmbar henholdsvis avkjølingsbar og i det minste i disse områder har varmevekselmulighet med trommeloverflaten.
