    Abstract: The invention relates to a method for adjusting a gap in a printing system in which a first roller and a second roller are provided, wherein at least one of said first roller and said second roller comprises a seam, said seam corresponding to a variation of the diameter of said first roller and said second roller, respectively, along a circumference thereof. An interaction zone is provided, wherein said second roller is in rolling contact with said first roller under pressure, said interaction zone defining a gap for inserting a media to be printed. A size of said gap is controlled by varying a relative position of said first roller and said second roller when said at least one seam passes through said interaction zone, and said gap is adjusted in accordance with a length of said media to be printed and/or in accordance with a length of an image to be printed.

    Abstract translation: 本发明涉及一种用于调整打印系统中的间隙的方法，其中提供第一辊和第二辊，其中所述第一辊和所述第二辊中的至少一个包括接缝，所述接缝对应于 所述第一辊和所述第二辊的直径分别沿其圆周。 提供了相互作用区，其中所述第二辊在压力下与所述第一辊滚动接触，所述相互作用区限定用于插入待印刷介质的间隙。 当所述至少一个接缝通过所述相互作用区域时，通过改变所述第一辊和所述第二辊的相对位置来控制所述间隙的尺寸，并且所述间隙根据要印刷的介质的长度和/ 或者根据要打印的图像的长度。
