INTERNAL COOLING TOWER FOR FILM BLOWING LINES

摘要

An internal cooling tower for a film blowing line with one or more superimposed cooling air nozzles designed such that the entrainment of droplets consisting of low-molecular components of the raw material that diffuse during the film blowing process from the film into the flow of cooling air is prevented. This is achieved in that at the height of the nozzle gap, the top surface of the cooling air nozzles has a grooved contour both on the inside and the outside.
