Problems solved by technology

Such inaccuracies or fluctuations lead to less precision in spreading and lead to produced material sheets having density inhomogeneities after pressing and thus possibly reducing their stability
In addition, there may be cosmetic damage due to identifiable density differences on the surface of the board

Embodiment Construction

[0051] exist figure 1 A structure 10 according to the invention for the continuous production of material sheets is shown in a schematic sectional view. The structure includes a spread store 12 to store a stock of spread 14 . The structure 10 further includes a forming belt 16 through which the spread 14 is fed into a continuous or discontinuous press (not shown) for pressing. Additionally, the structure 10 includes an optional spreading device 18 to continuously apply the spreading material 14 to the forming belt 16 . Direct spreading on the forming belt 16 is also possible with the spreading material store 12 , wherein indirect spreading is preferably carried out using a spreading head adapted to the spreading material 14 .

[0052] Such structures can be used in plants for producing panels of material. In such an apparatus, a spread reservoir 12 is used to buffer the glued material, referred to herein as a spread 14 . The spread storage 12 may also be referred to as a d...

Abstract

The invention relates to a spreading device (18) for continuously applying spread material (14) to an endless forming belt (16), comprising: for discharging the spread material from a spread material silo (12) The discharge roller (22); and the guide device (24) arranged between the discharge roller (22) and the forming belt (16) to further convey the unloaded spread material (14), wherein the guide device (24) It is configured to be adjustable in order to influence the spreading accuracy and / or the lateral distribution of the discharged spread (14) across the width (17) of the forming belt (16). The invention also relates to a method for continuously applying a spread material (14) to an endless forming belt (16) and a structure (10) for continuously producing material sheets. With the above devices, methods and structures, it may be possible to compensate for constant errors in the spread.

Description

technical field [0001] The invention relates to a spreading device, a method for continuously applying a spreading material to an endless forming belt, and a structure for continuously producing a sheet of material. Background technique [0002] In the production of material panels from spreadable materials, on a forming or conveyor belt (spreader belt conveyor) will be made of granular or fibrous substances (e.g. wood chips or other lignocellulosic material) and binders (e.g. glue) The mixture is spread into a spread mat. Subsequently, after any pretreatment that is required, this spread mat (also called mat or granulate mat) is subjected to continuous or discontinuous pressing, which can be carried out by means of pressure and / or heat. For example, MDF boards (medium density fibreboard) or OSB boards (oriented strand board or coarse strand board) can be produced in this way. [0003] At least a spread material storage (also referred to as a spread dosing silo) is provide...
