- the task for a procedure to be created and a system to be created, or device, is to produce a pressed material mat in the course of the process
- the solution for the method is that the press material mat is compacted in the course of transport to the press by means of a compacting device on its narrow sides transverse to the production direction.
- the solution for a device for compacting the narrow sides of a pressed material mat in a plant for the production of material plates, such as chip, chip, fiber or similar wood-based panels and plastic plates, with a press and at least one spreader for creating a pressed material mat from grit, is to in that in the device at least one means for compressing the pressed material mat by moving the

- the present invention preferably relates to the production of OSB material panels, of course, can also be applied in other manufacturing processes, such as MDF, chip or in the production of fiber insulation mats and panels.
- Fiber insulation mats have been improved and redeveloped over the last decade to become independent of plastic-based base material, thus reinforcing wood fibers with PMDI-containing adhesives or bicomponent fibers
- Narrow sides transverse to the transport direction (accompanied by a more or less strong reduction of the original width B1 or B2 width of the
- Pressgutmatte to a width B3) reduces the described phenomena of disintegration on the narrow sides in the course of transport, venting or active / passive fluidization.
- active fluidization is meant, for example, the introduction of steam, steam-air mixtures and / or pure hot air application for heating the pressed material mat and / or for activation of the binder.
- passive fluidization here means the use of a steam pulse that occurs when a moisture-containing pressed product mat comes into contact with heat-transferring means (heated or heated steel and / or fabric tapes) or heat within the material to be pressed (microwave, high-frequency) and thus within the pressed material mat, a steam front is formed, which preferably exits via the narrow sides.
- Stable narrow sides are desired in process applications that help to adjust some vapor or fluid mean pressure within the press mat, especially during compaction / compression / cure. Accordingly, a higher dense narrow side compared to the middle Areas of Pressgutmatte (across the production direction across the width) of advantage because here a kind of natural barrier is built.
- the device / system or the method can be configured as in the following embodiments:
- a wheel is arranged on at least one narrow side of the pressed material mat or over an edge region of the surface side, around a substantially vertical axis.
- the invention understands the surface and axis alignment of
- the pressed material is mat by means of a
- Scattering device substantially horizontally and preferably scattered on a moving and endlessly circulating forming belt, wherein the
- Pressgutmatte two surface sides (including one in contact with the forming belt) and two narrow sides, wherein the narrow sides parallel to
- the wheel respectively the axis thereof, preferably so employed to Pressgutmatte that during the
- the surface of the narrow side is pressed and / or displaced in the direction of the longitudinal center of the pressed material mat, thus reducing the width of the pressed material mat and increasing the density or compaction in the edge region (on the narrow sides) of the pressed material mat.
- the peripheral surface of the wheel can be shaped in this way or the axis of the wheel can have an angle to a vertical axis, so that the upper, free surface side of the pressed material mat is more compacted than the surface side of the pressed material mat lying on the forming belt.
- Main axis directions in the angle is adjustable, and thus at least two differentiated angles and geometries on the narrow sides of the pressed material mat are adjustable.
- the wheel preferably runs freely through the resulting friction on the pressed material mat, but depending on the material used in the pressed material mat can also usefully be driven, in particular regulated. It is alternatively possible to adjust the circumference of the wheel in synchronism with the production speed or even, depending on the desired effect, to rotate faster or slower, so that the peripheral surface of the wheel rotates faster or slower than the passing Pressgutmatte.
- the surface of the wheel may also be roughened in variations, provided with steps, printing patterns or the like.
- Pressgutmatte consists of oriented scattered chips) is a diameter of the wheel from 0.5 m to 2 m. This size is also conceivable with other scattered goods.
- the spreading material in the edge region can be pressed more against the spreading material running in the direction of production in order (in the direction of production after the
- the separate devices should be adjustable in their distance from the narrow sides of the pressed material mat to ensure optimum width adjustment of the pressed material mat and / or compression of the narrow sides.
- usually spoken by a device but preferably both narrow sides are uniformly equipped, so that a pressed material mat on both narrow sides, preferably at the same time, reduced by the compacting device in its width and the narrow sides are compacted.
- Pressgutmatte be compressed in a length transverse to the direction of production, which correspond to about 75% of the length of a chip (Spans), preferably up to 50% of the length of a chip.

- Figure 3 is an enlarged plan view of an embodiment with a
- Trimming device milling machine
- edge compaction by means of a compacting device (wheel) in front of the inlet of the pressed material mat in a press
- Figure 6 is a schematic plan view of the effect of a in
- Compaction device with an endless belt associated baffles.
- a system is shown in a schematic view starting with a spreader 1 1 over an endless forming belt 23 and a subsequent continuously operating press 16.
- the scattering device 1 1 scatters the incoming spreading material 10 onto the endless forming belt 23 as a pressed material mat 2.
- the scattering device 1 1 scatters the incoming spreading material 10 onto the endless forming belt 23 as a pressed material mat 2.
- the scattering device 1 1 thereby also a grit hopper (not shown separately), wherein the supply of grit 10 and its treatment (prefabrication) will not be further described.
- the created pressed material mat 2 in a pre-press 12 a pre-compression and possibly other pretreatments (for example, evaporation, humidification) experienced before entering the press 16.
- a discharge chute 13 Shortly before the press 16 is usually a discharge chute 13, in the
- Inferior or hazardous Pressgutmatten 2 can be dropped by means of a reversible Mechanismlassase 14. In general, it is afterwards in
- Production direction 22 an intermediate conveyor 15 which is optimally aligned for the pressed material mat 2 to the continuously operating press 16 to
