Abstract
In both axial end regions (5,6), each roller has a section (7,8) to grip and carry the tube (1) or its blank (3). Between sections (7,8), there is a first cylindrical section (13). The inner tool (4) has a penetrating section (10) at its axial end (9). This penetrates the tube blank. Adjacent to it, a further cylindrical section (11) works with the first cylindrical section (13) to elongate the tube (1).
