The tube winding device has a stationary cage (3), formed by rods (7, 8) between two rings (5, 6). The special feature is that at least some of the cage rods (8) are obliquely positioned and driven between the rings (5, 6) with respect to the cage axis by the helix angle of the band (2) to be spirally wound up, so that the band to be wound can be fed perpendicularly onto the driven rods (8). This makes it possible to utilise the frictional forces between the band (2) and rods (8) optimally and to wind and advance the tube further by the driving of the rods. <IMAGE> |
