Claims23
A doctor device in an inking unit of a rotary printing machine having a roller, the doctor device comprising:
- a base member;
- a working doctor adjustable with respect to the base member, said working doctor having a first position and a second position relative to said base member, in said first position said working doctor being set against the roller for doctoring ink in a desired result, in said second position said working doctor being set against the roller for stopping doctoring ink in the desired result;
- a sensor determining a respective one said first and second positions of said working doctor relative to said base member;
- and
- an indicating device connected to said sensor, said indicating device being activated by said sensor dependent on a determined one of said first and second positions of said working doctor relative to said base member.
