Abstract
The invention may relate, among other things, to a device for straightening a metal strip having two strip drives which are suitable together to apply tension on the metal strip to straighten the metal strip, wherein at least one of the strip drives is a linear drive, characterised in that the at least one linear drive has a positioning device such that the linear drive can be moved relative to the longitudinal axis of the device.
Claims4
A method for straightening a metal strip, the method including:
- inputting said metal strip to an inlet linear drive;
- outputting said metal strip from an outlet linear drive;
- and
- positioning one or both of the inlet linear drive or the outlet linear drive relative to one another depending on a position of said metal strip or on one or more other properties of said metal strip.
