Abstract
A device for the production of film tubes includes a die head having an annular nozzle, from which a plastic melt for producing the film tube can be extruded in a transport direction (y), a fluid-application device, which is annular in shape at least in certain regions and which follows the die head in the transport direction (y) and which surrounds the film tube annularly, and via which a fluid can be guided toward the film tube, and a ring, the diameter of which is larger than the annular nozzle of the fluid-application device. The device has an adjusting device, via which the ring can be adjusted in height relative to the fluid-application device.
