Specific lengths of tube sections have to be severed from a run of spiral seam tubes being produced, in order to facilitate handling and storage. A cutter, with which sections of tubes can be severed cleanly without the formation of burrs from the run of tubes, comprises a carriage that can be slid back and forth on guides at right angle to the axis of the tube and on which carriage are mounted in the cut plane a milling cutter and shears, both of which can be moved on the tube independently of each other and back again with controlled drives.
