Patent DE-4042122-A1 (DE)
Title: Efficiently cooling calendered film - by first passing through air jet or coolant and, after leaving gauging rollers, over series of small steel rollers or over endless metal band
Inventor: KOHLERT CHRISTIAN DR ING
IPC: B29C43/24
Filed: 1990-12-22
Abstract: In a process where films are cooled at the same time as they are calendered, the side of the film further from the roller is cooled by coolant or by small roller(s) or by a metal band when the film is in a smoothing calender or after it has passed the gauging gap concerned. This takes place without affecting the thickness profile of the film. ADVANTAGE - The calendered film is cooled to a mimimum core temp. after leaving the gauging rollers. The film is correspondingly solidifed. Any subsequent cooling process can therefore be omitted or at least minimal
