Actuating device for actuating element, e.g. for signature feeder, has thread-pitch of spindle correlated so that element is displaceable within angle range by no more than two rotations of spindle

摘要

The actuating element is rotatable about a first axis, and is engaged by a control element that is rotatable about a second axis, perpendicular to the first. The thread pitch of a threaded spindle (36.8, 36.8') is correlated with a predetermined setting-angle range, so that the actuating element is displaceable within the range by means of a maximum of two rotations of the threaded spindle.
