发明名称 Method and device for initial adjustment of the register of the engraved cylinders of a rotary multicolour press
摘要 To adjust peripheral register of engraved cylinders, the positions of a respective angular register mark arranged on each cylinder is measured with respect to a zero reference, and an angular printing mark characteristic of the position of the engraving is associated with each cylinder. The data of the job to be run are stored. The respective angular displacements of the engraved cylinders are indexed with respect to a reference cylinder in accordance with the job. By determining the web length separating two printing points of two successive engraved cylinders, this length is divided by the peripheral length of the cylinder and the remaining amount of the division is used for determining the angular indexing. Each cylinder is then brought into its angular indexed position, is first disconnected from a common transmission, and then all the cylinders are simultaneously reconnected to the transmission.
