Abstract
A doctor or doctor blade is embedded in an enclosure or casing formed of plastic. The portion of such enclosure covering the region of a work edge of the doctor blade is connected with the remaining part of the enclosure by means of a reference fracture location in the form of notch-shaped weakening lines. These weakening lines determine the separation location between both of the enclosure sections or portions. After mounting the doctor blade, protected by the enclosure or casing, the work edge is exposed by separating the enclosure portion or section covering the work edge, whereas the remaining part of the enclosure remains at the doctor blade.
