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 application 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 within 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.
Claims36
An apparatus for applying substances having differing viscosities to an application surface, comprising:
- an angularly adjustable doctor device and means for variably positioning the doctor device including a mount;
- said doctor device including a profile member having a first longitudinal axis, a doctor having a doctor pressing line guided by said profile member;
- and
- a retaining member having opposite ends wherein one end of the retaining member is supported by the mount and the other end of the retaining member is pivotally connected to the profile member by a joint having a second longitudinal axis such that the pivoting of the profile member about the joint is caused by a change in a spacing of the mount with respect to the application surface.
An apparatus for applying materials of different viscosities to an application surface using a doctor device, comprising:
- said doctor device having a magnetically pressable roll doctor having a circular profile and a pressing line contacting the application surface, and a profile member having at least one profile surface facing the application surface and extending parallel to a longitudinal axis of the roll doctor;
- means for moving the doctor device including a retaining member in the form of a retaining strip having opposite ends and a mount movable with respect to the application surface, wherein said retaining strip is mounted at one end to the mount and mounted pivotably at its other end to the profile member by a joint such that the profile member is spaced by the retaining member from the mount;
- and
- said profile member having an accumulation area for the application material upstream of the roll doctor whereby varying the height of the profile member with the moving means varies the area of said accumulation area.
An applicator for applying material of different viscosities with a doctor device, comprising:
- a magnetically pressable doctor and magnetic means for pressing the doctor against a substrate;
- an profile member provided with a pivot joint and means for holding and guiding said doctor wherein said profile member has at least one profile surface parallel to a longitudinal axis of one of the at least one said doctor.
