  • a holder 1 has a holding surface 2, on which a winding device 3 is arranged.
  • the winding device 3 has an annular support plate 4, which carries annularly arranged, freely rotatable support rollers 5 on the outer circumference of the tube to be wound, the axes of rotation 6 of which are parallel to one another.
  • the central axis 7 running through the center M of the circle formed by the axes of rotation 6 of the support rollers 5 and parallel to the axes of rotation 6 of the support rollers is equal to the central longitudinal axis of the tube to be wound.
  • two inlet rollers 9 and 10 are arranged which can be driven and which act on the two broad sides of the band.
  • the inner infeed roller 9 is arranged inside the winding device 3, while the outer infeed roller 10 is arranged outside the winding device.

  • the inner feed roller 9 has a lower peripheral speed than the outer feed roller 10.
  • the carrier plate 4 has an abutment surface 12 which extends to the central axis 7 at an angle of 90 ° by the pitch angle ⁇ of the pipe to be wound and which bears on the holding surface 2, so that the axes of rotation 6 of the Support rollers 5 or the central axis 7 intersect the plane designated by 13, determined by the axes of rotation 11 of the inlet rollers 9 and 10, in the pitch angle ⁇ .
  • the carrier plate 4 is arranged on the holding surface 2 such that the central axis 7, the plane determined by the axes of rotation 11 of the inlet rollers 9, 10, designated by 13 in the line of intersection of this plane with that through the center of the inlet rollers 9 and 10, perpendicular to the axes of rotation 11 of the infeed rollers run, 14 designated plane intersects.
  • the band 8 to be wound runs symmetrically to this plane, which is designated by 14.
  • the carrier plate 4 is arranged rotated about the central axis 7 in the winding direction indicated by the arrow 15 in such a way that the intersection line of the contact surface 12 designated with 16 has a plane perpendicular to the central axis 7 (in FIG. 2, for example the plane denoted by 17) which intersects the plane denoted by 13 through the axes of rotation 11 of the inlet rollers 9 and 10 and intersects at an acute cutting angle.
  • two drive rollers 18 are arranged on the holder 1, which also act on the broad sides of the belt 8.
  • the drivable drive rollers 18 are rotatable about axes of rotation 19 perpendicular to the holding surface 2, the plane running through the axes of rotation 19, designated by 20, running parallel to the plane designated by 13 through the axes of rotation 11 of the feed rollers 9 and 10.
  • a belt guide 21 is arranged between the drive rollers 18 and inlet rollers 9 and 10. The peripheral speed of the drive rollers 18 is greater than the peripheral speed of the outer feed roller 10.
  • a bending roller 22 is arranged, which can be rotated about an axis of rotation 23 perpendicular to the contact surface 2 and is displaceable and fixable on the holder in the direction of the central axis 7.
  • the bending roller 22 is set such that it projects beyond the connecting line between the entry point and the belt guide 21 in the direction of the central axis 7, as shown in FIG. 1.
  • the band In the manufacture of a tube by helically winding the band 8, the band is first fed in the direction of the arrow labeled 24 to the drive rollers 18, which feed it through the band guide 21 and via the bending roller 22 to the inlet roller pair 9 and 10 of the winding device 3.
  • the band 8 In the winding device, the band 8 is wound helically to form a tube, the feed rollers 9 and 10 establishing the connection of the incoming band with the tube that has already been wound.
  • the wound tube is withdrawn from the winding device 3 in the direction of the arrow labeled 25.
  • the peripheral speed of the inner infeed roller is less than the peripheral speed of the outer infeed roller, a secure guiding of the belt between the infeed rollers is ensured and the belt to be wikkeinde pressed firmly against the support rollers 5 of the winding device 3, so that the belt or the tube is held securely in the winding device 3 and high working speeds are possible.
  • This effect is reinforced by the fact that the peripheral speed of the drive rollers 18 is greater than the peripheral speed of the outer feed roller 10.
  • the ring-shaped carrier plate 4 is releasably attached to the holding surface 2 of the holder 1, so that another winding device with the corresponding diameter can be fastened to the holder 1 in order to produce a tube with a different diameter.
  • the fact that the inner feed roller 9 has a very small diameter not only facilitates the bending work, but it is also possible to produce tubes with a very small diameter.
