Abstract
A doctor for applying material, having a pressing part (doctor body) bending elasticly in the longitudinal direction and corresponding to the application width and a row of segments for pressing the pressing part, the segments (20) are connected in link-like manner by web or holding parts (203, 29, 39, 4, 40 to 48) to a unit-forming pressing device (2) pressing at least one pressing part (3, 30, 31, 32, 36), and the segments (20) being held independently to the pressing part (3, 30, 31, 32, 36).
Claims30
A doctor apparatus for the application of fluent material to a substrate over an application width with a doctor body, comprising:
- a pressing part forming the doctor body and corresponding in length to the application width for engaging a substrate along a substrate path;
- a pressing device for pressing the pressing part, said pressing device being lengthwise subdivided into segments;
- the pressing part being constructed in bending elastic manner over its length and supported over its length by a plurality of the segments along a side of each of said plurality of segments facing the substrate path;
- means for linking the segments together in a link-like manner only along said sides of each of said plurality of segments facing the substrate path;
- said pressing device pressing said pressing part toward the substrate path in a pressing direction;
- and
- means for loosely holding the segments to permit relative movement of the segments both in the pressing direction and transverse to the substrate path.
A doctor apparatus for the application of fluent material to a substrate over an application width with a doctor body, comprising:
- a pressing part forming the doctor body and corresponding in length to the application width for engaging a substrate along a substrate path;
- a pressing device for pressing the pressing part, said pressing device being lengthwise subdivided into segments;
- the pressing part being constructed in bending elastic manner over its length and supported over its length by at least one of the segments along a side of the at least one segment facing the substrate path;
- means for linking the segments together in a link-like manner, wherein said linking means includes a bending elastic strip arranged between the segment and the pressing part;
- the pressing part being separate from the pressing device;
- and
- said pressing device pressing said pressing part toward the substrate path.
A doctor apparatus for the application of fluent material to a substrate over an application width with a doctor body, comprising:
- a pressing part forming the doctor body and corresponding in length to the application width for engaging a substrate along a substrate path;
- a pressing device for pressing the pressing part, said pressing device being lengthwise subdivided into segments, wherein at least one segment has a recess along the application width with edges forming two parallel pressing parts;
- the pressing part forming the doctor body being constructed in bending elastic manner over its length and supported over its length by at least one of the segments along a side of the at least one segment facing the substrate path;
- means for linking the segments together in a link-like manner;
- the pressing part forming the doctor body being separate from the pressing device;
- and
- said pressing device pressing said pressing part toward the substrate path.
A doctor apparatus for the application of fluent material to a substrate over an application width with a doctor body, comprising:
- a pressing part forming the doctor body and corresponding in length to the application width for engaging a substrate along a substrate path;
- a pressing device for pressing the pressing part, said pressing device being lengthwise subdivided into segments, wherein the segments are superimposed transversely to the application width;
- the pressing part being constructed in bending elastic manner over its length and supported over its length by at least one of the segments along a side of the at least one segment facing the substrate path;
- means for linking the segments together in a link-like manner;
- the pressing part being separate from the pressing device;
- and
- said pressing device pressing said pressing part toward the substrate path.
A doctor apparatus for the application of fluent material to a substrate over an application width with a doctor body, comprising:
- a pressing part forming the doctor body and corresponding in length to the application width for engaging a substrate along a substrate path;
- a pressing device for pressing the pressing part, said pressing device being lengthwise subdivided into segments, wherein the segments are juxtaposed along the application width;
- the pressing part being constructed in bending elastic manner over its length and supported over its length by at least one of the segments along a side of the at least one segment facting the substrate path;
- means for linking the segments together in a link-like manner;
- the pressing part being separate from the pressing device;
- said pressing device pressing said pressing part toward the substrate path;
- and
- a holder on which each of the segments is articulated to be movable transversely to the application width.
