ABSTRACT:
The ink duct is separated by at least one separating wall which is fastened to the base and is formed from two metal plates (4, 5), fastened at a distance from each other and between which a plastic intermediate plate (6) is mounted with a tight fit and so that it can be displaced and tilted and is guided by a pin (17) which is fastened between the plates and passes through an oblong hole in the said intermediate plate (6). This intermediate plate (6) has a front edge (6a) which has the shape of an arc of a circle corresponding to the periphery of the ink duct cylinder. In the use position, it is pressed against this periphery by two spring pins (9,10; 12,13) which act on its rear edge so as to ensure a leaktight contact with the said ink duct cylinder. A positioning pin (18), which is fastened to the said plate (6), allows it to be pulled into the withdrawn position, where it may be locked. The leak-tightness with the base of the ink duct is achieved by a plastic sealing strip (25, 26) provided on the lower edge of the metal plates.
