摘要： The invention relates to a method for engraving printing cylinders used for rotogravure in an electronic engraving machine. According to this said method, at least two engraving sections (A, B) of a given width (SB) are fitted next to each other, in the acial direct ion of the printing cylinder (1). These sections (AB) are engraved with their respective engraving element (3). Before engraving, an axial reference position is pre-set for each engraving element (3). The axial spacing between these reference positions corresponds to the pre-set widths (SB) of the engraving sections (A, B). The engraving elements (3) are placed approximately in their reference positions (RP). The differences in the axial spacing between the reference positions of the engraving elements (3) and the actual positions occupied as a result of the approximate positioning are then measured. During engraving, the engraving elements (3) are moved along the printing cylinder (1), still incorrectly spaced as a result of the approximate positioning. The spacing errors are compensated by displaced engraving of the engraving sections (A, b) on the printing cylinder (1), so that the engraving sections (A, B) have the pre-set widths (SB) despite the incorrect spacing between the graving elements (3).
摘要翻译：本发明涉及一种用于在电子雕刻机中雕刻用于轮转凹版的印刷滚筒的方法。根据该方法，在印刷滚筒（1）的活塞直接离子中，至少两个给定宽度（SB）的雕刻部分（A，B）彼此相邻配合。这些部分（AB）刻有各自的雕刻元件（3）。在雕刻之前，为每个雕刻元件（3）预先设置轴向参考位置。这些参考位置之间的轴向间距对应于雕刻部分（A，B）的预设宽度（SB）。雕刻元件（3）大致位于其参考位置（RP）内。然后测量雕刻元件（3）的参考位置与作为近似定位的结果占据的实际位置之间的轴向间距的差异。在雕刻期间，雕刻元件（3）沿着印刷滚筒（1）移动，由于近似定位而仍然不正确地间隔开。间距误差通过对印版滚筒（1）上的雕刻部分（A，b）进行移位雕刻来补偿，使得雕刻部分（A，B）具有预设宽度（SB），而不管雕刻元素（3）。

摘要： A system for locating a plurality of engraving heads on an engraver wherein a plurality of engraving heads are automatically positioned into a predetermined configuration. A mechanism for positioning the engraving heads preferably includes a leadscrew and a drive nut which is rotatable relative to the leadscrew. In addition, each of the engraving heads preferably includes a rotatable drive nut with a respective motor for rotating the nut whereby the heads may be selectively positioned into a predetermined configuration. In a further aspect of the invention, the engraving heads are mounted on a carriage which is movable in an axial direction relative to a cylinder to be engraved. The heads are selectively positionable on the carriage and the carriage includes a nut threadably engaged with a leadscrew whereby the carriage may be driven in an axial direction relative to the cylinder to be engraved. In yet another aspect of the invention, a method is provided for engraving a cylinder including mounting a cylinder in the engraver, automatically adjusting a plurality of engraving heads into a predetermined configuration, and engraving a plurality of images onto the cylinder.
