FIELD: technological processes.
SUBSTANCE: stated invention is related to the field of plastics processing, to production of films, namely to devices for cooling of films made by extrusion through annular slot by upward blowing of tube. Technical result is achieved in device for cooling of tubular film made by extrusion through annular slot by upward blowing of tube. Device comprises extrusion head, annular sprayer for water supply to external surface of tube and facility for collection of water that flows down along tube. Besides facility for water collection is arranged in the form of bath installed on head via heat insulation ring that covers annular slot with its internal conic opening.
EFFECT: simplified technological process of film production, increased efficiency and improved quality of manufactured film.
