摘要： Printing apparatus for printing machines of the type having cylindrical screens and an endless carrying belt is disclosed which comprises a squeegeeing device consisting of an elastic membrane expansible by means of a pressurized fluid (such as air), said membrane being associated with an equalizing bar placed between the said membrane and a blade made of a flexible and elastic material acting on the internal surface of the screen with an acute incidence angle, said squeegeeing device being opposed to a counterpressure table inclined with respect to said endless carrying belt, said counterpressure table being provided with a lining consisting of layers of soft and yielding material and of an anti-frictional thin plate. The zone of contact between said endless carrying belt and said counterpressure table is placed downstream of the contact zone between the endless carrying belt and said screen. The said counterpressure table forms with the horizontal plane tangent to said screen an angle between 3* and 6*.
