ABSTRACT:
A device for producing film rolls, which is in particular suitable for producing coreless film rolls, comprises a roll holder for receiving a film roll comprising a film sheet to be wound off. The film sheet is wound up to a winding mandrel for producing the preferably coreless film roll. For producing in particular a coreless film roll the winding mandrel comprises a plurality of radially displaceable holding segments extending in longitudinal direction of the winding mandrel. After transfer of the winding mandrel, together with the wound-up film roll, to a transport means, the winding mandrel is transported to a delivery station. The delivery station serving for automatically delivering the wound-up film roll from the winding mandrel comprises a displacement means with the aid of which the holding elements of the winding mandrel are displaced into a delivery position. In this delivery position the outer diameter of the winding mandrel is smaller such that the film roll is delivered from the winding mandrel and falls onto a transport belt.
