    • A device and a method for widening elongated metal elements (11, 65) which move in the longitudinal direction and are planar at least in certain regions are described. The device comprises at least two clamping sections (19, 38, 49, 50) which are opposite one another and of which one is arranged and designed for clamping a first longitudinal side (22, 67) of the metal element in place and the other is arranged and designed for clamping a second longitudinal side of the metal element in place, said second longitudinal side being opposite the first longitudinal side of the metal element. The clamping sections are each provided on a support unit (15, 35, 36, 39, 40), by means of which the clamping sections, during the forward movement of the metal element, are automatically moved apart essentially perpendicularly to the direction of movement of the metal element.
    • 描述了用于加宽细长金属元件(11,65)的装置和方法,所述细长金属元件在纵向上移动并且至少在特定区域中是平面的。 该装置包括至少两个彼此相对的夹紧部分(19,38,49,50),其中一个夹紧部分被设置并设计成用于将金属元件的第一纵向侧(22,67)夹紧在适当位置,并且另一个夹紧部分 布置和设计成用于将所述金属元件的第二纵向侧面夹持就位,所述第二纵向侧面与所述金属元件的第一纵向侧面相对。 夹紧部分分别设置在支撑单元(15,35,36,39,40)上,通过该支撑单元在金属元件的向前运动期间,夹紧部分基本上垂直于运动方向自动地移动分开 的金属元素。
