Embodiment Construction

[0045] figure 1 The device 1 for producing a material sheet 60 is shown in side view from a spreading mat 50 which is spread in a spreading station 30 on an endlessly circulating forming belt 40 during the production of the material sheet 60 In the continuous working press 70 the pressing takes place in the production direction P between an upper steel belt 71 and a lower steel belt 72 by means of pressure and / or heat.

[0046] Compared with known devices, the device 1 according to the invention is characterized in that the forming belt 40 is configured to be uninterrupted from the spreading station 30 to the press 70 and includes a transfer leading to the lower steel belt 72. The lug 41 , and here together with the lower steel strip 72 delimits the transfer area 10 . What is special is, in particular, that the only transfer point is arranged on the press 70 directly after the pressable spreading mat 50 has been completely produced.

[0047] In particular, a transfer locatio...

Abstract

The present invention relates to an installation (1) and to a method for operating the installation for producing a material board (60) from a mat of scattered material (50) scattered on an endlessly circulating forming belt (40) in a scattering station (30), said mat of scattered material (50) being pressed by means of pressure and / or heat between an upper (71) steel belt and a lower (72) steel belt in a continuously operating press (70) during the production of the material board (60). The forming belt (40) is configured without interruption from the scattering station (30) to the press (70) and comprises a transfer nose (41) that leads up to the lower steel belt (72) and in the process defines a transfer region (10) with the lower steel belt (72). By the installation and the method, a major part of the transfer belt of the forming belt can be canceled, and the drop flow of the chippings of the lower coverage layer of the mat of scattered material is conducive to being minimized further, thereby facilitating improving the surface quality of the produced material board.

Description

technical field [0001] The invention relates to an apparatus for producing material panels according to the preamble of claim 1 . [0002] Furthermore, the invention relates to a method for operating a plant for producing material panels according to the preamble of claim 16 . Background technique [0003] Particle boards and the production of material boards from eg fibers (MDF, HDF), chips or strips (OSB) are currently automated processes and have been used for many years in many countries. The pressing of the prepared chips or fibers is either a periodic pressing or a continuous pressing. Continuous duty presses are used in the large industrial production of wood panels. In these presses, as described in DE 39 13991 C2, the pressing force is transmitted by means of hydraulic adjustment members to the pressing platen and heating plate and subsequently to the pressing material via steel belts via rolling body mats (rolling strips) ) is arranged in a supporting and rotati...
