  • the mandrel is associated with two winding assemblies each carried by a pivoting frame.
  • the arrangements according to the invention make it possible to reduce the angular sector covered by the bending plate and thus to place around the mandrel at least three winding assemblies in the manner shown in FIG. figure 1 .
  • the winding device of the document US Patent 2,918,226 is provided for winding a strip of relatively small thickness which can thus be stretched along the theoretical plane of travel (P) tangent, upstream, to a generatrix of the deflector roll D and, downstream, to a generator 22 of the mandrel 2.
  • the invention on the contrary, is provided for winding a hot strip of greater thickness, up to 25 mm and, therefore, more rigid. It is then more advantageous, as shown by figure 2 , that the generator 23 through which the plane of thrust Q is slightly offset downstream relative to the generator 22 corresponding to the theoretical direction of travel of the strip, so that it is subjected to a torque preclining before being clamped on the mandrel by the application roller.

  • the application roller 3 is rotatably mounted directly on the support frame 6 of the bending plate 4 and the assembly is pushed towards the mandrel by the actuating jack 62 bearing in a direction, on the foundation block by a fixed hinge 63 and in the other direction on the frame 6 by a hinge 64.
  • This jack 62 is provided as above, to control the displacement of the support frame 6 between the winding position shown in FIG. figure 1 and a separated position of removal of the coil.

  • This thrust force exerted, according to the invention, by the actuator (s) 62 of the chassis 6 can be much greater than in the previous provisions because it is balanced by the reaction of the mandrel and simply depends on the thrust capacity of the or cylinders 62 and the strength of the frame 6 and the joints 63, 64.

  • the outer face 30 of the roller 3 deviates from the outer face 12 of the strip 1 by a distance (d ) and that the roll 3 is no longer applied to the band, the driving effect F 3 f 3 being, therefore, eliminated.
  • the bending effect exerted by the curved plate 4 on the head 13 of the band tends to maintain the inner face 11 thereof applied to the outer face 20 of the mandrel 2 under an application force F 2 and, at the same time, to increase the angular sector of application on which this effort is distributed.
  • the strip 1 is subjected, by the mandrel, to a driving force F ' 2 f' 2 .

  9. Vorrichtung nach Anspruch 8, dadurch gekennzeichnet, dass sie drei in Wickelrichtung gesehen aufeinander folgend um den Dorn (2) angeordnete Wickelanordnungen umfasst, und zwar eine erste Anordnung (E1), die einen Winkelbereich des Dorns von ungefähr einem Viertelkreis zwischen einer ersten Anlegewalze (3) und dem Austrittsende einer ersten Biegeplatte (4) abdeckt, eine zweite Anordnung (E2), die einen Bereich von ungefähr einem Viertelkreis zwischen einer zweiten Anlegewalze (3b) und dem Austrittsende einer zweiten Biegeplatte (4b) abdeckt, und eine dritte Anordnung (E3), die einen Winkelbereich von ungefähr einem Viertelkreis zwischen einer dritten Anlegewalze (3c) und einer dritten Biegeplatte (4c) abdeckt, die sich bis zu einem Austrittsende erstreckt, das möglichst nahe an der Innenseite (11) des Bandes (1) vor der ersten Anlegewalze (3) angeordnet ist.
  10. Vorrichtung nach Anspruch 8, dadurch gekennzeichnet, dass sie vier aufeinander folgende Wickelanordnungen umfasst, und zwar drei Anordnungen (E1, E2, E3), die jeweils einen Winkelbereich von höchstens einem Viertelkreis zwischen einer Anlegewalze (3, 3b, 3c) und dem Austrittsende einer Biegeplatte (4, 4b, 4c) abdecken, und eine vierte Anordnung (E4), die mindestens eine vierte Klemmwalze (3d) umfasst, die unmittelbar hinter dem Austrittsende der dritten Biegeplatte (4c) angeordnet ist.
  11. Vorrichtung nach Anspruch 10, dadurch gekennzeichnet, dass die vierte Wickelanordnung (E4) eine vierte keilförmige Biegeplatte (4d) umfasst, die sich möglichst nahe an der Auflagemantellinie (21) der Bandlaufebene (P) am Dorn in dem Raumwinkel zwischen der Innenseite (11) des Bandes und der Außenseite (20) des Dorns (2) erstreckt.
  12. Vorrichtung nach einem der Ansprüche 8 bis 11, dadurch gekennzeichnet, dass jede Wickelanordnung (E1, E2, E3) an einem Rahmen (6, 6a, 6b, 6c) angebracht ist, der um eine ortsfeste Achse (60, 60b, 60c, 60d) gelenkig ist und zwischen einer Wickelposition und einer beabstandeten Position zum Entnehmen eines aufgewickelten Coils schwenkt.
  13. Vorrichtung nach Anspruch 12, dadurch gekennzeichnet, dass sie vor dem Dorn (2) eine Führungsrinne (7) umfasst, die mindestens zwei zum Raum zwischen der Klemmrolle und dem Dorn hin zusammenlaufende Platten umfasst, und zwar eine obere Platte (72b), die vom Rahmen (6) der ersten Wickelanordnung (E1) getragen wird, und eine untere Platte (71a), die vom Rahmen (6c) der letzten Wickelanordnung (E3) getragen wird.
  14. Verfahren zum Aufwickeln eines in Längsrichtung durchlaufenden Bandes (1) auf einen um eine senkrecht zur Bandlaufrichtung verlaufende Achse (21) drehangetriebenen Dorn (2) mit Hilfe von mindestens einer Wickelanordnung (E), die eine Anlegewalze (3), welche an einem Tragrahmen (6) angebracht ist und um eine parallel zu der des Dorns (2) verlaufende Achse (31) gegenläufig zum Dorn drehangetrieben wird, Mittel (62) zum Drücken der Anlegewalze (3) gegen den Dorn (2) entlang einer Andrückebene (Q) und eine Biegeplatte (4) umfasst, die am Rahmen (6) hinter der Anlegewalze (3) ausgebildet ist und eine gebogene Innenseite (41) zum Führen des Bandes (1) entlang der Außenseite (20) des Dorns (2) hat, dadurch gekennzeichnet, dass die Andrückkraft (F3), die von der Anlegewalze (3) auf den Dorn (2) aufgebracht wird, von mindestens einem Hydraulikzylinder (62) ausgeübt wird, der sich am Rahmen (6) zum Dorn (2) hin und in entgegengesetzter Richtung an einem ortsfesten Teil (M) abstützt, und dass im Fall der Entfernung der Antriebswalze (3) nach außen das Band (1) mit seiner Außenseite (12) an einer zusätzlichen Walze (5) zur Anlage kommt, die vor der Antriebsrolle (3) drehbar am Tragrahmen (6) angebracht ist und um eine parallel zu der des Dorns (2) verlaufende Achse (51) drehangetrieben wird, so dass auf das Band (1) eine Vortriebskraft ausgeübt wird, die zu der von der Anlegewalze (3) ausgeübten Antriebskraft addiert wird oder diese ersetzt.
  15. Verfahren nach Anspruch 14, dadurch gekennzeichnet, dass der Durchmesser und die Position der zusätzlichen Walze (5) am Rahmen (6) so bestimmt werden, dass unter Berücksichtigung der Biegung des Bandes (1) zwischen der Rückhaltevorrichtung (R) und dem Dorn (2) die Außenseite (12) des Bandes (1) bei einer Entfernung der Außenseite (50) der Walze (5) von der Außenseite (12) des Bandes (1) auf Ebene der Andrückebene (Q) um mehr als ein Viertel der Dicke (e) des Bandes (1) mit der zusätzliche Walze (5) in Kontakt kommt.
  16. Verfahren nach einem der Ansprüche 14 und 15, dadurch gekennzeichnet, dass die vom Andrückzylinder (62) auf den Tragrahmen (6) ausgeübte Andrückkraft und die auf den Dorn (2) und die Walzen (3, 5) aufgebrachten Drehmomente in Abhängigkeit vom Biegewiderstand des Bandes (1) eingestellt werden, so dass die Vortriebskraft, die durch Reibung von mindestens einer der beiden vom Rahmen (6) getragenen Walzen, d.h. der Anlegewalze (3) und der zusätzlichen Walze (5), auf die Außenseite (12) des Bandes (1) ausgeübt wird, und die Kraft, die vom Dorn auf die Innenseite (11) des Bandes (1) ausgeübt wird, in der Lage sind, eine ausreichende Biegung des Bandes (1) zum Aufwickeln dieses Bandes auf den Dorn (2) zu bewirken.
  17. Verfahren nach Anspruch 14, dadurch gekennzeichnet, dass die auf den Dorn (2) und die Anlegewalze (3) und/oder die zusätzliche Walze (5) aufgebrachten Drehmomente es ermöglichen, eine Vortriebsleistung zu erhalten, die in der Lage ist, zum einen den Vorschubwiderstand zu überwinden, den die Biegeplatte entgegensetzt, und zum anderen die zum Biegen des Bandes erforderliche Energie aufzubringen.
