    • The transporting device according to the invention, in particular for transporting sheet-like substrates through a coating installation, comprises transporting rollers which are rotatably mounted on both sides and horizontally arranged transversely in relation to the transporting direction, the uppermost surface lines of the transporting rollers defining the transporting plane, and is characterized in that the end parts of the transporting rollers have a smaller diameter than the middle part of the transporting rollers and in that baffles which are mounted displaceably in the axial direction of the transporting rollers between a first position and a second position are arranged between the end parts of the transporting rollers and the transporting plane. The fact that the baffles are mounted in an axially displaceable manner has the effect of considerably extending the cleaning intervals of the transporting device. At first the baffles are arranged in a first position, in which the end of the baffle lies underneath the substrate and, in the horizontal direction, as close as possible to the middle of the transporting roller Vapor-depositing material that gets beyond the edge of the substrate hits the baffle. During operation of the transporting device, the baffles are continuously displaced from the middle part to the ends of the transporting rollers. As a result, the increase in thickness of the layer produced on the baffles is limited, since the vapor keeps hitting new portions of the baffle.
    • 根据本发明的传送装置,特别是用于通过涂布装置传送片状基片的传送装置包括:输送辊,其可旋转地安装在两侧并相对于输送方向横向布置,输送辊的最上表面线 限定输送平面,其特征在于,输送辊的端部具有比输送辊的中间部分更小的直径,并且其中挡板在输送辊的轴向方向上可移动地位于第一位置和 在输送辊的端部和输送平面之间设置有第二位置。 挡板以可轴向移位的方式安装的事实具有显着延长输送装置的清洁间隔的效果。 首先,挡板被布置在第一位置,其中挡板的端部位于基板的下方,并且在水平方向上尽可能靠近输送辊的中部。气相沉积材料超出边缘的边缘 衬底撞击挡板。 在输送装置的运行过程中,挡板从传送辊的中间部分到端部连续地移位。 结果,在挡板上产生的层的厚度的增加是有限的,因为蒸汽持续击打挡板的新部分。
