Problems solved by technology

[0016] However, it is known in the state of the art to achieve a differently configured spreading mat for each change of the layer sequence, requiring expensive modifications to the arrangement of the spreading heads and / or to the embodiment. , the disadvantage is the refitting time and downtime of the scattered equipment or the entire equipment

Embodiment Construction

[0049] In the subsequent description of preferred embodiments according to the invention for the production of material plates or for the production of spread mats for subsequent pressing / hardening, the same reference numbers refer to the same or analogous parts. The production of scatter mats for oriented scatter boards (OSB) is perhaps the most complex structure, except for the production of scatter mats from MDF (Medium Density Fiber) or shavings, and the invention is also shown here its maximum utilization.

[0050] figure 1 A first embodiment of a spreading device 1 according to the invention is shown for producing a part of a spreading material mat 80 on an infinitely endless forming belt 70 arranged below the spreading head 30 in the falling direction of the spreading material 99 It is shaped and in particular pressed and / or hardened in a press (not shown) by means of pressure and / or heat during the production of the material sheet.

Abstract

The present invention relates to a scattering installation for producing a scattered particle mat, which is formed on a continuously circulating forming belt arranged under a scattering head in the falling direction of scattered particles. Arranged here are at least one metering bunker, intended for at least temporarily receiving scattered particles and operatively connected to a discharge device for the metered discharge of the scattered particles, and a scattering head, intended for scattering the scattered particles onto the forming belt that is present under the scattering head to produce at least part of the scattered particle mat, wherein the scattering head has at least one feed opening for receiving the scattered particles and at least one roller arrangement with rollers, intended for manipulating and / or scattering the scattered particles. The scattering installation according to the invention essentially comprises that the scattering head has at least one first feeding region and at least one second feeding region, at a distance from said first region in or counter to the direction of production, intended for feeding the scattered particles, and / or that at least one roller, preferably all the rollers, of a roller arrangement is / are suitable for changing its / their direction of rotation. By using the above features as alternatives or in combination, a scattered particle mat with a changed layer sequence can be advantageously obtained without requiring any conversion or idle time in the scattering installation (1).

Description

technical field [0001] The invention relates to a spreading device for producing a spreading mat according to the preamble of claim 1 . [0002] Furthermore, the invention relates to a method for operating such a spreading device according to the preamble of claim 12 . Background technique [0003] When producing material sheets from spreadable materials, the mixture of granular or fibrous substances and binders is spread to form a spread material mat on a forming belt or conveyor belt, wherein the spread material mat is then fed, if possible, to all The required pre-processing unit and finally fed to the pressing machine. This pressing can take place continuously or discontinuously by means of pressure and / or heat. Common material boards produced here are generally MDF, particle board or OSB boards or comparable multilayer boards. In particular in OSB boards an orientable spread is used, comprising the finest fraction (FK), finer fraction (GK, KS, LS) and / or coarser frac...
