BEKANNTMACHUNG DER ANMELDUNG UNDAUSGABEDER AUSLEGESCHRIFT: 19. OKTOB E R 1961NOTICE THE REGISTRATION ANDOUTPUTE EDITORIAL: OCTOBER 19, 1961
Bei der Herstellung von Holzleisten für Kleinparkett aus Rohfriesen wird bei bekannten Verfahren das Ausgangsbrett zunächst quer zur Faserrichtung in kurze Einzelbrettchen aufgetrennt, die anschließend zur Herstellung der Parkettlamellen weiterbearbeitet werden.In the production of wooden strips for small parquet from raw friezes, known processes are used the starting board is first divided into short individual boards transversely to the grain, which are then cut further processed to produce the parquet lamellas.
Es ist bekannt, eine Anzahl von Brettchen gleichzeitig durch Vewendung mehrerer paralleler Trennsägen herzustellen. Da die Rohfriese meist infolge der Trocknungsprozesse verzogen und windschief sind, sind die beim gleichzeitigen Auftrennnen hergestellten Stirnflächen der Einzelbrettchen nicht rechtwinklig zu ihren Oberflächen, so daß bei der späteren Bearbeitung dieser Oberflächen ein relativ großer Holzabfall entsteht.It is known to cut a number of boards at the same time by using several parallel cut-off saws to manufacture. Because the raw friezes are mostly warped and crooked as a result of the drying process are, the end faces of the individual boards produced during the simultaneous separation are not at right angles to their surfaces, so that a relative large wood waste is produced.
Zur Vermeidung dieses Nachteiles ist es bekannt, die Einzelbrettchen nacheinander einzeln von dem Rohfries abzulängen. Hierbei kann das abzulängende Ende des Rohfrieses jeweils derart ausgerichtet werden, daß ein nahezu rechteckiger Übergang zwischen den Stirnflächen und den Oberflächen der Brettchen nach dem Abtrennen vorhanden ist. Dieses Verfahren hat den Nachteil, daß die Leistung der entsprechenden Maschinen nur gering ist und daß ein Nachschieben oder Ausrichten der Rohfriese von Hand erforderlich ist.To avoid this disadvantage, it is known, the individual boards one after the other from the To cut raw frieze. The end of the raw frieze to be cut to length can be aligned in such a way that that an almost rectangular transition between the end faces and the surfaces of the boards is present after detaching. This method has the disadvantage that the performance of the corresponding Machines is only small and that a pushing or aligning of the rough friezes of Hand is required.
Der Erfindung liegt die Aufgabe zugrunde, das Auftrennen eines Rohfrieses in mehrere Einzelbrettchen derart zu ermöglichen, daß ein mindestens nahezu rechtwinkliger Übergang von den Schnittflächen zu den zwischen den Sägeblättern liegenden Oberflächen der Brettchen bei gleichzeitiger hoher Produktionsleistung ermöglicht wird.The invention is based on the task of separating a rough frieze into several individual boards to enable such that an at least almost right-angled transition from the cut surfaces to the surfaces of the boards lying between the saw blades and at the same time higher Production output is made possible.
Nach einem Verfahren zum Auftrennen eines Rohfrieses in mehrere Einzelbrettchen, deren Schnittflächen mindestens nahezu rechtwinklig zu den zwischen den Sägen befindlichen Oberflächen liegen, insbesondere zur Herstellung von Kleinparkettleisten, wird erfindungsgemäß der Rohfries auf einer Breitseite zunächst mit Einschnitten versehen. Anschließend wird eine Breitseite des Rohfrieses auf eine ebene Auflagefläche gedrückt, und daraufhin wird der Rohfries an den Einschnitten durchtrennt, derart, daß die Breite der Trennschnitte mindestens gleich der maximalen Breite der Einschnitte ist.According to a method for separating a raw frieze into several individual boards, their cut surfaces are at least almost at right angles to the surfaces between the saws, in particular for the production of small parquet strips, the raw frieze is according to the invention on a broad side initially provided with incisions. Then a broad side of the raw frieze is on a pressed flat support surface, and then the raw frieze is cut at the incisions, in such a way, that the width of the separating cuts is at least equal to the maximum width of the cuts.
Durch die Einschnitte wird der Rohfries geschwächt, so daß die Innenkanten dieser Einschnitte beim Anpressen an die ebene Auflagefläche keilförmig zusammen- oder auseinandergedrückt werden. Die Verziehungen des Brettes werden auf diese Weise ausgeglichen. Die anschließenden Trennschnitte, deren Breite größer als die Maximalbreite der Ein-Yerfahren zum Auftrennen eines Rohfrieses in mehrere EinzelbrettchenThe raw frieze is weakened by the incisions, so that the inner edges of these incisions be pressed together or apart in a wedge shape when pressed against the flat support surface. The warping of the board is compensated in this way. The subsequent separating cuts, whose width is greater than the maximum width of the retraction for cutting a raw frieze into several individual boards

Die Schnittverluste sind bei diesem Verfahren geringer als beim Einzelablängen. Die Produktionsleistung ist ebenso groß wie bei den bekannten Verfahren des Mehrfachablängens, ohne daß das erfindungsgemäße Verfahren die Nachteile des üblichen Mehrfachablängens aufweist.The cutting losses are lower with this process than with individual cutting. The production output is just as large as in the known method of multiple cutting to length without the inventive Process has the disadvantages of the usual multiple cutting to length.
Die Erfindung wird an Hand der Zeichnungen näher erläutert. Es ist dargestellt in Fig. 1 ein verzogener Rohfries, Fig. 2 der Rohfries nach dem Einritzen,The invention is explained in more detail with reference to the drawings. It is shown in 1 shows a warped raw frieze, FIG. 2 shows the raw frieze after the scratching,
Fig. 3 der eingeritzte Rohfries nach dem Anpressen an die Auflagefläche,3 shows the incised raw frieze after it has been pressed against the support surface,
Fig. 4 der in Einzelbrettchen aufgetrennte Rohfries.4 shows the raw frieze separated into individual boards.
Der Rohfries 1 gemäß Fig. 1 ist verzogen, so daß seine Oberflächen 4, 5 Unebenheiten aufweisen. Der Fries ist auf eine Fläche 2, die z. B. durch die Wandung einer rotierbaren Trommel gebildet sein kann, aufgelegt.The raw frieze 1 according to FIG. 1 is warped so that its surfaces 4, 5 have unevenness. Of the Frieze is on a surface 2, which z. B. can be formed by the wall of a rotatable drum, hung up.
Nach dem ersten Verfahrensgang enthält der Rohfries 1 Einschnitte 6 unterschiedlicher Tiefe. Diese Einschnitte werden von parallelen Sägen, die im Abstand 3 voneinander angeordnet sind, ausgeführt.After the first process step, the raw frieze contains 1 incisions 6 of different depths. These Incisions are made by parallel saws, which are arranged at a distance of 3 from each other.
Das Brett wird nun, wie aus Fig. 3 ersichtlich ist, gegen die Auflagefläche 2 gedrückt. Hierbei werden je nach Krümmung des Brettes die Innenkanten der Einschnitte 6 keilförmig auseinander- oder zusammengedrückt. Das Brett ist nun nahezu eben undAs can be seen from FIG. 3, the board is now pressed against the support surface 2. Here will be Depending on the curvature of the board, the inner edges of the incisions 6 are wedge-shaped apart or pressed together. The board is now almost level and

Fig. 4 zeigt die Einzelbrettchen 8 nach dem Auftrennen. Die Oberflächen 9 und 10 dieser Brettchen verlaufen rechtwinklig zu den Schnittflächen 7.4 shows the individual boards 8 after they have been separated. The surfaces 9 and 10 of these boards run at right angles to the cut surfaces 7.
