Description

Gegenstand des Patents 918 352 ist ein Holzstab, insbesondere für Selbstroller und Rollos, der durch Zusammenleimen der Kanten und Segmente einer in der Achsrichtung des Stabes mit Einschnitten versehenen und achssymmetrisch zu einem Rohr zusammengebogenen: Holzplatte, insbesondere aus Furnier, hergestellt ist.The subject of patent 918 352 is a wooden stick, in particular for Self-roller and roller blinds made by gluing the edges and segments of a provided with incisions in the axial direction of the rod and axially symmetrical to bent into a tube: wooden panel, in particular made of veneer is.

Es wurde nun gefunden, daß sich diese Holzstäbe besonders einfach und haltbar herstellen: lassen, wenn man: die Einschnitte in der zusammenzubiegenden Holzplatte, insbesondere dem Furnier, in Form vom: Rillen mit Hilfe einer Profilwalze eindrückt.It has now been found that these wooden sticks are particularly easy and make it durable: let, if you: the incisions in the one to be bent Wooden board, in particular the veneer, in the form of: grooves with the help of a profile roller depresses.

Die Erfindung sei nachstehend an Hand der Abbildung näher erläutert, die im Längs- und Querschnitt eine geeignete Vorrichtung zur Erzeugung der Rillen schematisch darstellt. Darin bedeuten,: A die Profilwalze, deren Achse mit dem Antriebsrad B versehen; ist und im Lager C läuft. D ist eine Holzplatte, vorzugsweise ein Furnier, die in den Hohlraum zwischen der Profilwalze A und der Gegenwalze E, die eine glatte Oberfläche besitzt und nicht angetrieben sein: muß, eingeführt wird. Durch Verstellen des Abstands zwischen den. Oberflächen der Walzen kann; man; die Tiefe der Rillen den: Verschiedenheiten, des Materials anpassen.The invention will be explained in more detail below with reference to the figure, which schematically shows a suitable device for producing the grooves in longitudinal and cross-section. Therein mean: A the profile roller, the axis of which is provided with the drive wheel B ; and is running in warehouse C. D is a wooden board, preferably a veneer, which is inserted into the cavity between the profile roller A and the counter roller E, which has a smooth surface and does not have to be driven. By adjusting the distance between the. Surfaces of the rollers can; one; Adapt the depth of the grooves to the differences, of the material.

Beim Durchlaufen, der Holzplatte durch die Vorrichtung verdichten die Kämme der Profilwalze das Holz an den. Flanken der Keilrillen. Es ist zweckmäßig, die Keilwinkel etwas größer, als theoretisch zurr Bildung einer lückenlosen, Innenwand des Rohres beim Zusammenbiegen erforderlich ist, zu halten. Dadurch wird das Einbringen. des Leimes und das Z»sarn?nemb'egen erleichtert. Durch. die Feuchtigkeit des Leimes quillt das verdichtete Holz wieder auf, füllt die Fugen und bewirkt einen hohen, Preßdruck.When passing through the device, compress the wooden panel the combs of the profile roller the wood to the. Flanks of the V-grooves. It is appropriate the wedge angle is somewhat larger than theoretically for the formation of a gapless inner wall of the pipe when bending is required to hold. This will bring in. of the glue and the Z-sarn? nemb'egen relieved. By. the moisture of the glue the compacted wood swells up again, fills the joints and creates a high, Press pressure.

Im übrigen arbeitet man gemäß dem Hauptpatent.Otherwise one works according to the main patent.
