Trailing element of a headbox of a machine for manufacturing a fibrous web, method for producing the trailing element and use of the trailing element

摘要

The separating element (1) of a multi-layered stock inlet of a machine for producing paper-, cardboard- or tissue web, comprises a separator blade (2) formed from a laminate (15) having three layers and a hinge-joint (3) arranged at an upstream end (4). The hinge-joint having a base body is embedded between the two layers forming a part of the hinge-joint. The layers have a layer thickness of 0.4-2.0 mm. The upper and the lower layers consist of same materials. The middle layer is arranged in a region turned away to the upstream end. The separating element (1) of a multi-layered stock inlet of a machine for producing paper-, cardboard- or tissue web, comprises a separator blade (2) formed from a laminate (15) having three layers and a hinge-joint (3) arranged at an upstream end (4). The hinge-joint having a base body is embedded between the two layers forming a part of the hinge-joint. The layers have a layer thickness of 0.4-2.0 mm. The upper and the lower layers consist of same materials. The middle layer is arranged in a region turned away to the upstream end. The base body has a circular, oval, elliptical or polygonal cross-section form. The base body consists of same material as the layers and is formed from a solid material or hollow material. The regions forming the hinge-joint have external layer materials with specially adjusted resin characteristics like the friction in the hinge-joint region or the wear resistance of the hinge-joint. The external layer materials are provided with friction-reducing particles and with a coating like a film or a lacquer at the outside of the materials, so that a friction in the hinge-joint region is minimized. An independent claim is included for a procedure for producing a separating element of a multi-layered stock inlet of a machine for producing paper-, cardboard- or tissue web.
