As native Croatian I can't find any logical explanation about this:
"Before new doctor blades are mounted, the positive doctor blade (7) is cut in an angle of 10 x 45°"
What does it mean:
-is reduced in an angle between...?
-is cut (as with a knife)?
-or...???

positioned at the desired angle
"cut in" the blade at an angle, fix it into a position to be able to function to the desired effect.
The angle of the edge of the doctor blade is a factor, but not critical. None of the relevant information is making a point of choosing a blade sharpened to a particular angle, the text below simply says, that if the blade wears out, the angle of the blade changes, becomes uneven, so the blade will have to be changed.
On the other hand the angle of the blade to the cylinder is critical, and it has to be adjusted to achieve the desired effect.
"Application:
.....Once the blade is mounted into the holder and positioned in the press, the angle at which the blade contacts the cylinder is critical. The best wiping angle is one that minimizes cylinder wear, wipes cleanly, and allows the greatest press speed.
Blade Angle. Two factors affect the blade angle. First is the angle on the blade itself. On beveled edge blades, wear may cause this angle to change. Pre-sharpened blades are used to minimize this problem by controlling the beveled edge thickness.
The second factor, the set angle, is the actual angle that results from the application of the blade to the cylinder by the blade holder. Set angles are typically between 25-35o. The set angle may change due to blade or cylinder wear and ink type. The angle is not a permanent setting. It can be altered to achieve the best wipe under the current conditions.
For example, a steep angle is used to remove more ink from the cells. This is commonly done in four color process printing when large amounts of ink are not needed. A flat angle is used when printing large solids or coatings. This leaves more ink in the cells, resulting in greater transfer."

If you look at the picture mentioned by Deborah,

it shows, that the blade is at an angle to the cylinder, but it is the other side of the blade where the sharpening is, to create the sharpness of the blade. That is the side away from the cylinder, and that's where the surplus ink collects, but that is not the determining factor. It is more important, that the angle between the cylinder and the blade is set correctly, because that determines the amount of ink remaining.

See the description of the process at http://www.wmich.edu/ppse/pekarovicova/101199.html
Here you can see an illustrations of blades cut at 45 degrees (i.e., cut in an angle of 45 degrees)

As I understand it, the blade has its own angle and then it is applied at another angle. The success of the process depends on controlling both.

Discussion
But, I think it's "positioned" because I have a picture in which the blade can be seen at an angle of approx. 45°. Next sentence (after the one quoted) is:
"This will prevent a dripping from the ends of the doctor blade."
Context (I think) suits better to the explanation offered by "juvera".
Thanks for the help!
