Embodiment Construction

[0032] exist figure 1 The first device 1 shown in the figure for coating a metal strip 2 has a coating device 3 by means of which the metal strip can be moved along a transport track 4 in the strip running direction 5 2 Apply coating medium (not shown). The direction of travel 5 of the strip points here towards the inside of the drawing. The coating device 3 shown in this embodiment is characterized by an upper coating unit 6 placed on the upper side 7 of the transport track 4 and a lower coating unit 8 placed on the lower side 9 of the transport track 4 . The application units 6 and 8 here comprise application roller elements 10 and 11 , which are held in the upper application unit 6 and the lower application unit 8 in a rotationally driven manner with rotational shafts 12 and 13 , respectively. Furthermore, a further roller element 10A and 11A is assigned to each application roller element 10 and 11 , so that each of the two application units 6 and 8 is equipped with at le...

Abstract

The invention relates to a method for coating a metal strip (2) moving in the strip running direction (5), in which method the metal strip (2) is guided past an application device (3) for applying a coating medium, in such a way that the coating medium is applied to a metal strip surface of the metal strip (2) by means of an application roller element (10, 11) of the application device (3), wherein, during the application of the coating medium, the metal strip (2) is moved relative to the application roller element (10, 11) transversely with respect to the strip running direction (5), in order to avoid coating faults on the metal strip surface to be coated.

Description

technical field [0001] One aspect of the invention relates to a method for coating a metal strip moving in the direction of strip travel according to the preamble of claim 1 , in which the metal strip is guided past a coating An application device for the coating medium, such that the coating medium is applied to the metal strip surface of the metal strip by means of the application roller elements of the application device. [0002] Another aspect of the invention relates to a device for coating a metal strip moving in the direction of travel of the strip according to the preamble of claim 4, the device having a coating device comprising at least one coating roller element. Coating device, which is used for coating the coating medium on the metal strip surface of the metal strip; Strip guide device, which is used for conveying along the guide through at least one coating roller element in the running direction of the strip Rails to guide the metal strip; feeding means for ad...
