Abstract
An apparatus for adjusting a scraper bar in a line for producing a paper web, having a wire, assigned to which are scraper bars oriented transversely to its direction of movement and situated at a distance from one another. The scraper bar is supported by a support bar and is adjustable with respect to the support bar and with respect to the wire by means of a positioning device. The scraper bar and the support bar are coupled together by way of links that are mounted thereon. The distance or the angular position of the scraper bar with respect to the support bar and thus with respect to the wire is adjustable by a displacement of the scraper bar with respect to the support bar.

An apparatus for adjusting a scraper bar in a line for producing a paper web with a wire and scraper bars oriented transversely to a direction of movement of the wire and situated at a spacing distance from one another, the apparatus comprising:
- a support bar supporting the scraper bar adjustably with respect to said support bar and with respect to the wire;
- a positioning device for adjusting said scraper bar with respect to said support bar and with respect to the wire;
- links mounted to the scraper bar and to said support bar for coupling the scraper bar and said support bar to one another;
- wherein a distance or an angular position of the scraper bar with respect to said support bar and with respect to the wire is adjusted by a displacement of the scraper bar with respect to said support bar;
- and
- support plates attached to the scraper bar and to said support bar and linking elements mounted on said support plates, said linking elements having pivot bolts oriented transversely to a longitudinal direction of the scraper bar and/or the direction of sliding.
An apparatus for adjusting a scraper bar in a line for producing a paper web with a wire and scraper bars oriented transversely to a direction of movement of the wire and situated at a spacing distance from one another, the apparatus comprising:
- a support bar supporting the scraper bar adjustably with respect to said support bar and with respect to the wire;
- a positioning device for adjusting said scraper bar with respect to said support bar and with respect to the wire;
- links mounted to the scraper bar and to said support bar for coupling the scraper bar and said support bar to one another;
- and
- wherein a distance or an angular position of the scraper bar with respect to said support bar and with respect to the wire is adjusted by a displacement of the scraper bar with respect to said support bar;
- and
- a support plate attached to said support bar and having mounted thereon first ends of two linking elements, wherein pivot axes of said linking elements together enclose an acute angle of 1° to 10°, wherein second ends of said linking elements are mounted on support elements, which are mounted on a support plate attached to the scraper bar, wherein pivot axes of said linking elements mounted on said support elements and the pivot axes of said support elements, which are mounted on said support plate attached to the scraper bar, intersect one another spatially.
An apparatus for adjusting a scraper bar in a line for producing a paper web with a wire and scraper bars oriented transversely to a direction of movement of the wire and situated at a spacing distance from one another, the apparatus comprising:
- a support bar supporting the scraper bar adjustably with respect to said support bar and with respect to the wire;
- a positioning device for adjusting said scraper bar with respect to said support bar and with respect to the wire;
- links mounted to the scraper bar and to said support bar for coupling the scraper bar and said support bar to one another;
- wherein a distance or an angular position of the scraper bar with respect to said support bar and with respect to the wire is adjusted by a displacement of the scraper bar with respect to said support bar;
- and
- wherein said positioning device comprises a pivotable angled lever mounted on said support bar and a positioning rod having a first end linked to said angled lever and a second end linked to the scraper bar, wherein the scraper bar is capable of displacement parallel to said support bar by pivoting said angled lever.
