Summary:Methods and apparatus for locally changing a roll gap in the region of strip edges (10) of a rolled strip (1) in a rolling stand (2). The roll gap can be changed locally in the region of the strip edges (10) of the strip (1) during the hot rolling. Axial displacement of working rollers (3, 4) in opposite directions is achieved by a displacement distance s, wherein s is greater than or less than [delta]r/tan(alpha), [delta]r indicates the wear of a running surface (8) in the radial direction (R) and alpha indicates the pitch angle of a conical portion (7) of the respective working rollers (3, 4). 本发明涉及用于局部改变轧制架（2）中的轧制带材（1）的带材边缘（10）区域中的轧辊开度的方法和装置。打算通过本发明能够在热轧期间局部改变带材（1）的带材边缘（10）区域中的轧辊开度。这个目的根据本发明是通过沿相反方向轴向移动工作辊（3、4）移动距离s来实现，其中s大于或小于，并且指示操作表面（8）在径向方向（R）上的磨损，而指示相应的工作辊（3、4）的锥形部分（7）的节锥角。
