"Verfahren und Vorrichtung zur Herstellung langgestreckter Körper durch Verpressen von Holzschnitzeln oder Holespänen11 "Method and device for the production of elongated bodies by pressing wood chips or wood chips 11

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Herstellung länglicher Körper beliebigen Querschnitts, wie beispielsweise von Balken, Pfählen oder von Rohren, durch Verpressen von Holzschnitzeln oder Holzspänen in einer Form·The invention relates to a method and an apparatus for the production of elongated bodies of any cross-section, such as beams, piles or pipes, by pressing wood chips or wood chips into a mold

Werden Holzschnitzel in einer Pressform aufgeschichtet, so bilden sich horizontale Schnitzellagen, die in zusammengepresstem Zustande zu Presskörpern mit horizontal verlaufender faserung führen· Diese horizontale Faserung bewirkt, dass die Presskörper •iner starken Bruchgefahr ausgesetzt sind. Diesem übelstand steuert die Erfindung wirksam dadurch, dass die waagerecht verlaufenden Holzschnitzel- oder Holzspane-Lagen beim Verpressen winkelförmig abgebogen werden derart, dass sich die einzelnen Lagen gegenseitig verzahnen'und verankern mit der folge, dass die Bruchgefahr der verpreesten Körper völlig aufgehoben wird·If wood chips are piled up in a press mold, horizontal chip layers are formed, which are compressed Conditions lead to pressed bodies with horizontally running grain · This horizontal grain causes the pressed bodies • Are exposed to a high risk of breakage. The invention effectively controls this inconvenience in that the horizontally extending wood chip or wood chip layers are bent at an angle during pressing in such a way that the individual layers are aligned interlocking and anchoring each other with the result that the risk of breakage of the pressed bodies is completely eliminated

die Pressform die Spänelagen in Zickzackform umbildet und sie auf diese Weise gegenseitig verzahnt.the press mold reshapes the chip layers in a zigzag shape and interlocks them in this way.

In der Zeichnung sind in Abb. 1 und 6 zwei verschiedene Ausführung sb ei spiele des zur Durchführung des erfindungsgemässen Verfahrens geeigneten Stössels perspektivisch dargestellt. Abb. 2 zeigt das Ende eines gepressten Rohrstückes« In Abb· 3-5 sind Querschnitte verschiedener Presskörper dargestellt»In the drawing, Fig. 1 and 6 show two different versions sb ei games for carrying out the method according to the invention suitable ram shown in perspective. Fig. 2 shows the end of a pressed pipe section «In Fig. 3-5 are Cross-sections of various pressed bodies shown »

Figo 1 zeigt einen mit Spitzen 1 versehenen hohlen, ringförmigen Stössel 2, mit welchem das in Abb. 2 dargestellte Rohr 3 gepresst werden kanno Die Planken der Stösselspitzen 1 sind bei 4 gezahnt. Es wird damit sichergestellt, dass die Holzschnitzel oder Holzspäne vom Stössel so erfasst werden, dass sie bei dessen Pressbewegun-g mitgerissen werden.Figo 1 shows a spiked 1 hollow annular plunger 2, with which the in Fig. 3 shown pipe 2 can be pressed o The planks 1, the plunger tips are serrated at 4. This ensures that the wood chips or wood shavings are caught by the ram in such a way that they are carried along when it is pressed.

Zur Herstellung runder Stangen oder Balken ist der in Abb. 6 dargestellte Stössel 2 geeignet, der konzentrisch zur Stössellängsachse angeordnete, ebenfalls mit Spitzen besetzte Fortsätze 5,6 geringeren Durchmessers aufweist« Damit wird gewährleistet, dass die Holzschnitzellagen in allen Bereichen des Formquerschnittes ineinander verzahnt werden·For the production of round bars or beams, the one shown in Fig. 6 is used The plunger 2 is suitable, the extensions 5, 6, which are arranged concentrically to the longitudinal axis of the plunger and also have points smaller diameter «This ensures that the wood chip layers in all areas of the shape cross-section be interlocked
