  • the pressed material mat is pre-compressed in the inlet mouth in a pre-compression zone upstream of the inlet plates up to an inlet gap height h 0 and then pressed in the region of the inlet plates and finally the heating plates.
  • EinlaufspaltSh means in the invention, the height of the press nip or the inlet gap in the region of the leading edge of the upper and / or lower inlet plate or in the region of the axis or shaft of the upper and / or loweradosrades for the rolling rods.
  • - Wood-based panels means in the context of the invention, in particular fibreboard, (eg MDF boards), chipboard or OSB boards (Oriented Strand Board).
  • the inlet plates are preferably designed as heatable Einlaufsammlungn. Furthermore, it is preferably highly flexible inlet plates, wherein the upper inlet plate and / or the lower inlet plate for adjusting the inlet contour is acted upon by a plurality of cylinder piston assemblies.
  • the inlet gap height does not fall below a certain minimum value, this minimum value having been selected taking into account the mat height of the incoming spreading material mat (eg 75% of the mat height).
  • the infeed system is preceded by a position measuring system which measures the chip / fiber mat height with a displacement sensor and forwards it to a computer.
  • the measured value is the manipulated variable for the hydraulic actuators for the upper inlet plate sections (cf. DE 43 01 594 A1 ).
  • the invention has the object of providing a generic method for pressing pressed material mats in a continuous press of the type described above in such a way that you can work in the inlet mouth with high densities without damage or disturbances are to be feared.
  • the invention teaches in a generic method for pressing Pressgutmatten in the course of the production of wood-based panels in a continuous press that checks the Einlaufspalt Escape depending on the density and / or the basis weight of the pressed material mat, adjusted and / or regulated.
  • the invention is based on the recognition that it is expedient if the inlet gap height, z. B. in the region of the insertion, not depending on the mat height of the scattered mat, but in dependence on the density or the basis weight of the mat is adjusted.
  • the invention proposes that the described review, adjustment and / or regulation taking into account a predetermined target basis weight occurs. Because in the course of spreading the grit mat is usually entered by the operator at a given Form Beaunum a target value for the basis weight, the actual basis weight is used to control the spreader or control.
  • the setting according to the invention of the desired setting height h 0 can then be carried out on the basis of this predetermined setpoint value of the basis weight of the spreading material mat, since this setpoint value is constant as a pure default value at least over a certain period of time.
  • Target weight or target surface weight means in the context of the invention, in particular the so-called “pushed” target surface weight, the addition “pushed” makes it clear that z.
  • the belt scale for determining the target basis weight is arranged upstream of the inlet gap with a predetermined distance. It is therefore taken into account in the review or setting the time delay between the time of setting the target weight and the time at which the relevant mats section enters the inlet gap.
  • the setting based on the setpoint has the advantage that it does not have to respond to any weight fluctuation.
  • the invention also encompasses those method variants in which the inlet gap height is checked, set and / or regulated as a function of the actually set basis weight actually set.
  • the invention proposes that the weight per unit area of the mat is (continuously) measured continuously in front of the inlet mouth and the inlet gap height is then regulated (continuously) as a function of these measured values.
  • the inlet mouth means within the scope of the invention, an area in front of the inlet mouth, which no further processing of the mat and in particular no further compression follows, before it then enters the inlet mouth of the press.
  • the invention proposes a "density-guided mode of operation", ie the inlet gap height, or its permissible minimum value, is no longer checked (exclusively) taking into account the mat height of the incoming press material mat and adjusted, if necessary, but a setting takes place taking into account the setpoint values. or actual basis weight.
  • the invention is based on the recognition that the pressing process can be carried out very effectively if a strong compression already takes place in the inlet mouth and possibly even in the region of a pre-compression zone in front of the inlet plates. Now, for example, grit mats with Pressed relatively low density, it can be done within the scope of the invention, a relatively strong precompression, which would have been previously inhibited in only one evaluation of the mat height.
  • a perfect adaptation of the inlet gap height to the properties of the pressed material mat can always be carried out, with the invention as a whole starting from the knowledge that a more exact adaptation of the inlet gap height becomes possible taking into account the weight per unit area.
  • press material mats having a relatively high density and low mat height which have been pretreated, for example, in a strong (separate) pre-press
  • the inlet gap height be chosen such that a further pre-compression in the pre-compression zone is completely dispensed with. Consequently, the method according to the invention functions independently of whether working with non-pre-pressed or only slightly pre-pressed mats or with strongly pre-pressed pressed material mats.
  • this defective filling device is controlled with dependence on the basis weight and / or the inlet gap height.
  • a misfire device usually consists of a misfed hopper arranged below the mat transport and an adjustable strip section arranged above it, so that the grit mat produced is dropped into the hopper with the hopper open and is fed to the press only in the case of the "closed" hopper.
  • the defective filling device will not be closed until the set inlet gap height is within the given value Way corresponding to the basis weight.
  • a control of the inlet gap height ie the inlet gap height is adjusted taking into account the (determined) basis weight, possibly several times or virtually continuously or at predetermined time intervals or continuously.
  • a "real" regulation of the inlet gap height is effected as a function of the weight per unit area. For this purpose, it is expedient that the inlet gap height is determined with a suitable measuring device and fed into the control process.
  • the inlet gap height is set or regulated at a desired or actual basis weight with the proviso that the nominal density ⁇ 0 of the mat in the area of the inlet gap does not exceed a maximum predetermined limit value ⁇ max exceeds.
  • the inlet gap height is then adjusted or regulated only as a function of the desired or actual basis weight (in kg / m 2 ).
  • the invention is based on the recognition that in the area of the inlet gap a certain maximum density must not be exceeded. From the quotient of the weight per unit area on the one hand and the inlet gap height on the other hand, the density of the mat produced in the area of the inlet gap is obtained directly. In other words, the inlet gap height results from the quotient of the one hand (nominal) basis weight and on the other hand the maximum mat density ⁇ max . This can be a real one Density measurement of the mat before entering the press be waived.
