Description
DEUTSCHESGERMAN
Es sind Vorrichtungen zur kontinuierlichen Herstellung von Spanplatten bekannt, bei denen vor der Heizpresse Besäumsägen angeordnet sind.There are devices for the continuous production of chipboard known in which before Heat press trimming saws are arranged.
Der Erfindung liegt die Erkenntnis zugrunde, daß diese Besäumsägen, die durch das noch nicht ausgeheizte Spanmaterial schneiden, vielfach Flugspäne hochschleudern und auf die Deckschicht des Vlieses werfen. Dadurch wird dessen Güte, falls es aus ausgewähltem Material besteht, nachteilig beeinflußt, oder aber es müssen verhältnismäßig kostspielige und zeitraubende Maßnahmen vorgesehen werden, um die Deckschicht von diesen ungewünschten Beimengungen wieder zu befreien.The invention is based on the knowledge that these trimming saws, which have not yet been baked out Cutting chip material, throwing up flying chips and onto the top layer of the fleece throw. As a result, its quality, if it consists of selected material, is adversely affected, or but relatively expensive and time-consuming measures must be taken to prevent the To free the surface layer from these undesired admixtures again.
Demgemäß besteht die Erfindung darin, daß in der Besäumzone eine die Vliesoberfläche gegen Flugspäne schützende Abdeckung vorgesehen ist.Accordingly, the invention consists in the fact that the fleece surface against fly chips in the trimming zone protective cover is provided.
Dabei ist es zweckmäßig, daß diese Abdeckung als Andrückvorrichtung für die Vliesoberfläche ausgebildet ist.It is useful that this cover is designed as a pressing device for the fleece surface is.
Die Erfindung ist an Hand der schematischen Zeichnung beispielsweise erläutert.The invention is explained using the schematic drawing, for example.
Fig. 1 zeigt in der Längsansicht einen Boden a, über den das obere Trum eines nach rechts laufenden Förderbandes b geführt ist.Fig. 1 shows a longitudinal view of a floor a, over which the upper run of a conveyor belt running to the right b is guided.
Aus drei in der Förderrichtung hintereinanderliegenden Bunkern c, d, e wird Spanmaterial verschiedener Art, das bereits beleimt sein kann, in drei übereinanderliegende Schichten verschiedenartiger Struktur und Beschaffenheit aufgegeben. From three bunkers c, d, e lying one behind the other in the conveying direction, chip material of different types, which can already be glued, is fed into three superimposed layers of different structures and properties.
Die noch unregelmäßig geformten Längsräder/ (Fig. 2) des auf diese Weise gebildeten dreischichtigen, aber noch formbaren Vlieses, das durch eine Kaltpresse g- (Fig. 1) hindurchgegangen und beispielsweise durch eine Kreissäge h in Platten quer unterteilt worden sein kann, werden durch zwei weitere Kreissägen i besäumt.The still irregularly shaped longitudinal wheels / (Fig. 2) of the three-layered, but still malleable fleece formed in this way, which can have passed through a cold press g- (Fig. 1) and, for example, be divided transversely into panels by a circular saw h, are trimmed by two more circular saws i.
Dabei wirkt in der Zone zwischen den Besäum sägeni von oben eine das Vlies andrückende Abdeckung k. Sie gewährleistet einen glatten Schnitt und eine saubere Schnittkante. Vor allem verhindert sie ein Auffallen von Flugspänen, auf die häufig aus ausgewähltem Material gebildete Deckschicht.In the zone between the trimming saws i, a cover k pressing the fleece acts from above. It ensures a smooth cut and a clean cut edge. Above all, it prevents flying chips from falling onto the top layer, which is often made of selected material.
Darauf erfolgt in einer anschließenden Heizpresse / das Ausheizen der Platten.This is followed by a subsequent heating press / the plates are baked out.

Erst anschließend schneiden zwei weitere seitlich angeordnete Besäumsägen m die ausgeheizten Platten auf endgültige Breite mit glatten Seitenrändern.Only subsequently cut two further laterally arranged edgers m the baked-out plates on final width with smooth edges.
Das vom Vorformling abgetrennte Material bildet keinen Abfall im eigentlichen Sinne, sondern wird unverzüglich zur nochmaligen Verwendung, beispielsweise in den Bunker d zurückgeführt, um nunmehr zur Bildung der Mittelschicht des Vlieses verwendet und somit voll ausgenutzt zu werden.The material separated from the preform does not form waste in the actual sense, but is immediately returned for further use, for example in the bunker d , in order to now be used to form the middle layer of the fleece and thus fully utilized.
