Embodiment Construction

[0039] Not every detail of the continuous working press is shown in complete detail in the drawings. The prior art described and fully based here is known to the person skilled in the art, so that for the description of the production method, according to figure 1 and especially in conjunction with figure 2 is enough. figure 1 The overall construction of a continuous-action press 1 is shown schematically, which in its basic construction always has two endless steel belts 2 and 3 running around a deflection drum 10 . The pressed blank 7 is fed into the feed section area I / II, wherein according to the prior art, this pressed blank 7 is usually laid on a forming belt (not shown) by means of a laying machine (not shown) and optionally The pressed blank 7 is compacted after precompacting by means of a prepress (not shown). in accordance with figure 1 In the embodiment described above, feed section heating plates 16 are arranged above and below, and these feed section heating p...

Abstract

The invention relates to a method for producing material slabs in a continuously operating press (1) in which a And the steel belts (2, 3) supported via the rollers (4) subject the pressed blank (7) to clamping and / or compaction in the feed section region preceding the main pressing region, wherein in the feed section region In the feed section heating plate (16) and / or hinged plates (12, 13) for adjusting the geometry of the feed section gap (E) along the production direction can adjust the feed section heating plate (16) and / or the spacing of the hinge plates (12, 13) and / or the ability to be bent. The solution of the present invention consists in using, from one surface side (33), during passage through the feed section regions (I, II), at least in one section along the production direction (22) A substantially rectilinear feed section heating plate (16) or at least two substantially rectilinear hinged plates (12, 13) perpendicular to the production direction (22) for clamping and / or compacting the compacted blank (7) , and from the opposite surface side (33) utilizing a feed section heating plate (16) bent perpendicular to the production direction (22) at least in the region along the longitudinal center line (LML) in the direction of the pressed blank (7) Clamping and / or compacting the compact (7). Furthermore, the invention also relates to a continuously working press.

Description

technical field [0001] The invention relates to a method for producing material sheets in a continuously operating press according to the preamble of claim 1 and a method for carrying out the method according to the preamble of claim 14 Continuous duty press. Background technique [0002] The production of particle boards and, for example, boards of medium density fiber materials is now an automated process and has been widely used in many countries for many years. As described in "Wooden Materials, Production and Processing" by Hansgert Soine, 1995 (DRW Verlag) p. 17 et seq., preprocessed wood chips are pressed either in a rhythmic or continuous manner or fiber. In addition to the many equipment units before and after the press, the production of the compacts by means of the paving machine plays a prominent role; however, in addition to the quality of the raw material, the quality of the compacts produced is also an important factor. [0003] The pressed preforms are pro...
