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 present invention relates to a method for producing composite panels in a continuously operating press (1). In the continuously operating press (1), the pressing blanks (7) are clamped and / or pressed in an area of material feeding segment before a main pressing area along a production direction (22) through steel strips (2,3) which operate around a bending roller (10) and are supported through a rolling rod (4), wherein in the area of material feeding segment, a material feeding segment heating plate (16) and / or hinging plate (12,13) which are used for regulating the geometric dimension of the material feeding segment clearance (E) along the production direction can adjust the clearance of the material feeding segment heating plate (16) and / or the hinging plates (12,13) and / or can be bended. The settlement solution of the utility model is characterized in that: in passing the areas (I,II) of the material feeding segment, the basically linear material feeding segment heating plate (16) which is perpendicular with the production direction (22) and at least two basically linear hinging plates (12,13) that are perpendicular with the production direction (22) are used on a surface side (33) in at least one segment along the production direction (22); and the bended material feeding segment heating plate (16) which is bended perpendicularly with the production direction (22) at least in the area along a longitudinal middle line (LML) along the direction of the pressing blank (7) from the opposite surface side (33). Additionally, the invention also relates to a continuously operating 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 Hansgert Soine, "Wooden Materials, Production and Processing", 1995 (DRW Verlag) p. 17 et seq., preprocessed wood chips are pressed either in a certain rhythm or in a 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 preform...
