ABSTRACT:
To indicate externally of a printing machine the position of a turning bar, the turning bar (15) drive spindle (1) is coupled to a numerical indicator (11) by a worm gearing (8, 9). The numerical indicator, having a plurality of number wheels, is capable of indicating the position of the turning bar (15) on a traverse rod (14). Preferably, a stop wheel (6) having ball-loaded detents at its circumference provides for predetermined angular positions of fractional revolutions of the spindle.
