Abstract

See full text

The invention relates to a device for calibrating and cooling a film or sheet of plastic which comprises at least two cooling or calibrating rolls (1), the rolls being followed by a downstream cooling zone (7). According to the invention, it is in this case provided that the downstream cooling zone (7) comprises pairs of rolls (2, 3, 4) arranged one behind the other. The invention also relates to a method for calibrating and cooling a film or sheet of plastic which comprises the steps of: introducing a film coming from a slot die into the nip between two cooling or calibrating rolls (1), polishing the film (5) between the two cooling or calibrating rolls (1), cooling the film (5) in a cooling zone (7). Here it is provided according to the invention that the cooling zone (7) comprises a number of adjustable rolls, the rolls being arranged in such a way that, at every operating point of the extrusion installation, the cooling of the film (5) largely corresponds to the theoretical thermal conductivity of the film (5).
