Beschreibung
Zusammenfassung:	The invention relates to a method for preventing shape changes in metal coils (1), in particular for preventing a collapsing of newly wound hot coils (1). In the method, a metal coil (1), in particular a newly wound hot coil (1), is rotated (3) about its longitudinal axis (2) intermittently in a first rotational direction (5) and then rotated back (4) in a second opposing rotational direction (6), or further rotated (17) in the first rotational direction (5). 本发明涉及一种用于避免在金属卷材（1）中的形状变化、尤其用于避免新卷绕的热卷材（1）的坍塌的方法。在所述方法中规定了：所述金属卷材（1）、尤其新卷绕的热卷材（1）围绕其纵向轴线（2）间歇地沿第一转动方向（5）正转（3）并且随后沿相反设置的第二转动方向（6）反转（4）或者沿第一转动方向（5）继续转动（17）。
