ABSTRACT:
The doctor device has a profile member pivotally mounted to a retaining member that is carried on a mount. Vertical movement of the mount causes angular displacement of the profile member thereby changing the material applicaton area disposed adjacent and upstream of the doctor. The doctor is either a doctor blade or roll doctor. In the case of a roll doctor, a receptacle is formed in the profile member and the roll doctor is magnetically retained with the receptacle. During application of a material to an application surface with the roll doctor, the roll doctor is magnetically attracted to the application surface by a second magnetic device located beneath the application surface or work surface.
