    • The invention relates to a heating device for a moving material strip, especially a preheater for a corrugated board machine. Said heating device comprises a rotating heating cylinder (3) around which the material strip (13) to be heated is able to wrap at a predefined angle of wrap, and at least two guides (7, 11) for the material strip which can be pivoted about the circumference of the heating cylinder while maintaining their relative positions to each other. The angle of wrap is determined by the position of a first (7) of the at least two guides. A second (11) of the at least two guides is positioned in relation to the first guide in such a way in that in that position of the guides which defines the maximum angle of wrap, the material strip (13) which is not in direct contact with the heating cylinder (3) is guided by the second guide (11) at a distance from the heating cylinder. The invention provides for a third guide (9) which, as seen in the direction of circumference of the heating cylinder (3), in a position defining the minimum angle of wrap which position is opposite the position defining the maximum angle of wrap, completely lifts the strip away from the circumference of the heating cylinder (3).
    • 本发明涉及一种用于移动的材料幅的加热装置,特别是预热器用于瓦楞纸板的安装,与旋转热辊(3),其是从被加热的材料幅(13)以预定的包角的umschlingbar,以及至少两个导向件(7,11) 为材料幅,其可摆动共同,同时保持围绕加热辊的圆周它们彼此的相对位置。 包角由第一的位置来确定所述至少两个导向件(7)。 所述至少两个导向件的第二(11)相对于所述第一引导件设置成使得在所述定义不具有热辊(3)立即通过在距离所述第二引导件(11)周围的材料带(13)缠绕导的最大包角位置 被引导至加热辊。 根据第三引导件(9)设置了本发明,在加热辊的圆周方向(3)可知,在相对的位置上与包装的最大角度,涡卷限定位置的最小角度完全从加热辊的范围抬起幅带(3)。
