Abstract
A blow film line and a method for operating the same relates to improving the flow rate in conventional blow film lines without compromising the production quality. The inner cooling body shows an air outlet path, with a cooling ring being embodied in a height-adjustable fashion, with a controller positioning the cooling ring in a lower area of the inner cooling body for the start-up of the facility. The cooling ring is positioned in the upper area of the air outlet path of the inner cooling body in order to achieve the steady-state production.
