CA 2572489

Directional drives are for example used upstream of coilers in mill stands for coiling up the strip in a defined manner. A first roll (5) that can be placed against a second roll (6) is used to adjust or control the desired strip tension and a lateral deviation of the strip. The directional drive (1) according to the invention has an especially simple design and can be controlled in a very precise manner. For this purpose, the rockers (2, 3) on which the roll (5) which can be placed against the second roll is mounted are separately mounted in a frame (12) so as to be swiveled and can therefore be swiveled independently.

Des dispositifs d'entraînement directionnels sont utilisés par exemple en amont de dévidoirs de bande dans des trains de laminoir pour pouvoir enrouler la bande de manière prédéfinie. Un second cylindre (5) pouvant être placé contre un premier cylindre (6) permet d'ajuster ou de régler une traction souhaitée de la bande et une déviation latérale de la bande. Le dispositif d'entraînement directionnel (1) selon la présente invention possède une structure particulièrement simple et peut être commandé de manière très précise étant donné que les éléments oscillants (2, 3) dans lesquels le second cylindre (5) est monté, sont montés pivotants et séparément l'un de l'autre sur un châssis (12), lesdits éléments oscillants pouvant ainsi pivoter de manière totalement indépendante l'un de l'autre.
