Abstract
Each individual, freely rotatable ring of a spiral-type ductor is mounted on an eccentric which is supported for rotation on a multi-eccentric shaft is angularly offset relative to its adjacent eccentric portion by at least an amount corresponding to the number of rings. The multi-eccentric shaft is connected to the drive of an inking system directly while the eccentric is connected thereto through a pinion, a pinion shaft, a gear and a separate sequential transmission with an integral speed ratio. In consequence, the center of the ring describes a curve which is flattened in the zone where the ring is in contact with an inking roller. The contact duration is thereby extended without varying the speed.
