    An inking apparatus for a rotary offset and a letter press printing machine comprises a wedge inkwell, a ductor (1) rotatable against a doctor blade (3) of the wedge inkwell (2) as well as a settable doctor blade (8) for the ductor (1) and disposed above the wedge ink well (2). The doctor blade (3) of the wedge inkwell (2) is disposed at a small gap S tangential to the ductor (1) and projects beyond the intersection (4) with the normal (5) of the ductor (1) against the direction of rotation thereof. The blade (3) is preferably resiliently mounted. <IMAGE>

    This invention relates to printing. This invention relates to an inking machine for rotary, offset and letterpress machines. Colorful devices are known which have a wedge-shaped colorful tank rotating against the colorful knife of the wedge-shaped, colorful tank ductor shaft, as well as located Above the wedge-shaped paint reservoir on the dector shaft, an adjustable squeegee (for example US-PS 3.288.061). In these inks, it is disadvantageous that the paint is partially removed from the ducting shaft with a knife of a wedge-shaped paint reservoir, collected and thereafter must be pumped back into the wedge-shaped paint reservoir, with the last operation with high viscosity paints, which are primarily used with offset printing, creates additional difficulties. The purpose of the invention is to simplify the design of these inks: while maintaining their full working capacity. The invention is based on a dacha, when in a paint apparatus with a wedge-shaped reservoir rotating against the paint knife of the wedge-shaped paint reservoir with a duct shaft, and also above the wedge-shaped paint reservoir and the adjustable squeegee interacting with the ductor shaft for residual paint remaining on the blower shaft, perform the entrance to the wedge-shaped colorful reservoir from below so that located: below the wedge-shaped colorful reservoir the paint receiver, as well as the pump a nite unit for the return of paint, became superfluous. The goal is achieved by the fact that the colorful knife of the wedge-shaped kLa reservoir is located with a gap in relation to the surface of the ductor shaft and stands at the point of intersection of the surface of the ductor shaft with a normally held to the surface of the ink knife. Through the wedge-shaped clearance of the wedge-shaped paint reservoir, the residual paint is not removed with a knife from the ductal shaft, but is fed completely back into the wedge-shaped paint reservoir. Other advantages of paint machines of this design, such as reducing the effect of paint contamination on controlling paint supply due to clogging of the gap on the wedge-shaped paint reservoir, as well as making full use of the paint it contains, compared to paint machines of a conventional design without a fast-folding paint knife and rotating in the opposite direction, the ductor shaft with the inking apparatus equipped in accordance with the invention, remains full an awn The invention can be varied advantageously in such a way that the colorful knife, in the area of the gap between the ductor shaft and the wedge-shaped colorful tank, becomes elastically deformable. An effect occurs in the inking machine operating state, the inlet gap for the paint increases due to the velocity head of the back-applied residual paint, while the inlet gap When the ink apparatus is idle, due to the absence of the velocity head of the ink and thereby reducing the elastic deformation of the ink knife , reduces the yield of paint. The set screws create the possibility of a good match between the gap on the wedge-shaped paint reservoir and the residual paint remaining on the ductor shaft. In the example of the following implementation, the invention provides a year-by-year explanation. FIG. 1 shows a colorful an-parat, 1d from the side; in fig. 2 - a variant of a colorful knife with a spring support. In accordance with FIG. 1, on the ductor shaft 1, from the side of the shirt, the wedge-shaped colorful reservoir 2 is located in the working position in such a way that the colorful knife 3 fixed on it is positioned in relation to the ductor shaft 1 under a slight gap S. At the same time, the colorful knife stands for the intersection point 4 with a normal 5 rotating against the colorful knife 3 of the ducting shaft 1 against its direction of rotation, as a result, in wedge-shaped color
