Embodiment Construction

[0037] figure 1 A device 1 according to the invention for applying a liquid or pasty coating medium onto a movable material web in the form of a fibrous material web F is shown in a schematically simplified illustration. In order to display the respective directions mentioned in the description, a coordinate system is typically added to the device 1 . The X direction describes the longitudinal direction of the device 1 , which coincides with the direction of passage of the fibrous material web F through it. The Y direction describes the width direction, that is to say the direction transverse to the direction of passage of the fibrous material web, and the Z direction corresponds to the height direction.

[0038] The device 1 is shown here as a separate, ie stand-alone device. As an in-line device, it can be immediately downstream of the device for producing the fibrous web F, wherein the introduction of the fibrous web F then takes place directly from the machine for produc...

Abstract

The invention relates to a device (1) for directly or indirectly applying a liquid to pasty application medium in the form of at least one free-falling curtain (3) to a moveable material web, in particular a fibrous web (F), said device comprising at least one application unit (2) and a capturing system (10) which is associated with the application unit (2) for capturing the application medium in an application-free operational phase. Said capturing system (10) comprises a capturing device (11) and a plate-shaped element (12) with interacts with said capturing device and which comprises a surface area (13) for guiding the application medium into the capturing device (11) in the application free operational phase. The invention is characterised in that said plate-shaped element (12) is arranged, during the application-free operational phase, opposite a horizontal plane (EH) at an angle (Gamma) including +-1 DEG - +-20 DEG , preferably including +-5 DEG - +-15 DEG and when the tear-off edge of the end area (14), directed away from the capturing device (11), of the plate-shaped element (12), penetrates the curtain, the height of the cut (H2) increases to a value between and including 5 mm -100 mm, preferably 5 mm - 60 mm, more specifically 10 mm - 40 mm, ideally, preferably 10 mm - 30 mm.

Description

technical field [0001] The invention relates to a device for directly or indirectly applying a liquid or pasty coating medium in at least one free-falling sag onto a movable material web, in particular a fibrous material web, with At least one coating mechanism and a collection system that can be associated with the coating mechanism for collecting the coating medium during the non-coating operating phase, which consists of the device until the release of the coating medium on the counter surface Characterized by the opening, the end of the coating to the mating surface or the interruption of operation, the collection system includes a collection device and at least indirectly co-acting with it and relative to it and / or a coating mechanism that is translatable relative to it and / or Sheet-shaped element translatable by the coating mechanism with at least one contoured edge at the end region facing away from the collection device, which passes through the sagging during the non-...
