For adjusting the ink gap on a ductor roller (1), a pin (3) is pressed onto the duct blade (2), the position of which pin can be adjusted by an adjusting lever arm (4) which is adjustable by means of a rotatable eccentric (7). The eccentric (7) is firmly connected to a toothed escapement wheel (6) to which a sprung catch member (13) and, on each side thereof, a pawl (18a, 19a), which is rotatable together with a shaft (16, 17), and an actuating arm (18b, 19b) are assigned. The pawl (18a, 19a) is engaged with the escapement wheel (6) by a pivoting finger (20, 21), actuated by a magnet (14, 15), and turns said escapement wheel in each case by one tooth in the clockwise or anticlockwise direction. When the magnet remains switched on, this is repeated until a cutout (24) in the escapement wheel (6) makes further switching impossible. A cable drive (10) and an indicator (12) connected thereto are adjusted by the escapement wheel (6), said indicator allowing the degree of inking to be read off. <IMAGE> |
