A device for production of tubes, includes a plurality of mandrel assemblies, each comprising multiple mandrels on which the tubes can be produced in steps at a plurality of work stations, wherein the mandrel assemblies can be transported from work station to work station using transport means. The mandrels of at least one of the mandrel assemblies are distributed into a first and at least a second mandrel group, and in at least one of the work stations the first mandrel group can be moved from a processing position associated with the work station, in which the work station can interact with the first mandrel group to a park position associated with the work station, and the second mandrel group can be moved from a park position associated with the work station to a processing position associated with the work station.
