Abstract (en)
[origin: WO2021255026A1] The invention describes a blow-moulding installation for producing tubular plastics film • with a die head, comprising an annular outlet for discharging a polymer melt, • with a take-off for taking off in a transporting direction the melt and the tubular plastics film forming therefrom, • with a cooling tower, arranged downstream in the transporting direction and arranged within the tubular outlet of the die head, wherein the cooling tower comprises at least one fluid-outlet gap, from which a fluid can be conducted in a radial direction onto the inner side of the melt and/or of the tubular plastics film. The fluid-outlet gap comprises at least one interruption.
