Description
Furnier-Fugen-Verleimmaschine. Die Erfindung bezieht sich auf eine Fur- nier-Fugen-Verleimmaschine, in welcher die Furniere während ihrer Längsbewegung in der Maschine an den einander zugekehrten Kanten mit Leim versehen und dann .durch Paare konvergierend gestellter Rollen gegen einandergedrückt werden. Bei bekannten Ma schinen dieser Art sind die Rollen in der För- derriehtung gesehen in Abständen von etwa 120 mm und mehr angeordnet.
Diese Maschinen haben sich gut bewährt, wenn ein sehr rasch abbindender Leim ver wendet werden konnte. Bei weniger rasch ab bindendem Leim, z. B. Kunstharzleim, zu des sen Anwendung man mehr und mehr über gegangen ist, weil der rasch abbindende Haut leim nicht in ausreichender Menge zur Ver fügung steht, versagte jedoch die bewährte Verleinunasehine. Es stellte sieh nämlich heraus, dass die Furnierbahnen, nachdem sie die Masehine verlassen hatten,
an ihrem rüek- wärtigen Ende auseinanderklafften.
Es stellte sich nun heraus, dass man bei Verwendung von Kunstharzleimen bessere Resultate erzielt, wenn man für das Anein- anderpressen der Furnierkanten Ansehiebe- rollen von geringerem Abstand in der Ma schine verwendet. Dementsprechend sind bei der erfindungsgemässen Maschine mindestens zwälf Rollenpaare auf den laufenden -Meter angeordnet.
Ein Ausführungsbeispiel soll in na.ehste- hendem an Hand der ganz schematischen Zeichnung erläutert werden.
Mit a ist der Tisch der Maschine bezeich- net. In diesem Tisch läuft eine hier nicht ge zeichnete Förderkette, um die durch Verlei- mung zu verbindenden, ebenfalls nicht ge zeichneten Furnierstreifen in der Richtung des rechts eingezeichneten Pfeils durch die Maschine zu bewegen.
Die Furniere gelangen unter die An schiebe- oder Fügerollen b, die an der Unter seite eines zweckmässig in Höhe verstellbaren Balkens c paarweise angeordnet sind, und zwar derart, dass sie in der Förderrichtung konvergieren. Der Einfachheit halber sind nur die dem Beschauer zugekehrten Rollen gezeichnet. Die weiter hinten befindlichen Rollen sind verdeckt.
Der Abstand d der Rollenmitten vonein ander in der Förderrichtung ist nun derart, da.ss auf den laufenden Meter mindestens zyvölf Rollenpaare kommen. Dementsprechend sind auch die Rollendurchmesser so weit ver ringert worden, da.ss sie jenen kleinen Ab stand. erlauben.
Veneer joint gluing machine. The invention relates to a veneer-joint gluing machine in which the veneers are provided with glue on the mutually facing edges during their longitudinal movement in the machine and then pressed against each other by pairs of converging rollers. In known machines of this type, the rollers in the conveyor direction are arranged at intervals of about 120 mm and more.
These machines have worked well when a glue that sets very quickly could be used. With less quickly from binding glue, z. B. synthetic resin glue, to whose application one has gone over more and more, because the rapidly setting skin glue is not available in sufficient quantities, but the proven Verleinunasehine failed. It turned out that the veneer sheets, after they had left the Masehine,
gaped at their back end.
It now turned out that when using synthetic resin glues, better results are achieved if one uses closer spacing rollers in the machine to press the veneer edges together. Accordingly, in the machine according to the invention, at least twelve pairs of rollers are arranged on the running meter.
An exemplary embodiment is to be explained in the following on the basis of the very schematic drawing.
The table of the machine is designated with a. A conveyor chain, not shown here, runs in this table in order to move the veneer strips, also not shown, to be joined by gluing through the machine in the direction of the arrow shown on the right.
The veneers get under the pushing or joining rollers b, which are arranged in pairs on the underside of a beam c, which is expediently height-adjustable, in such a way that they converge in the conveying direction. For the sake of simplicity, only the roles facing the viewer are drawn. The rollers further back are covered.
The distance d of the roller centers from one another in the conveying direction is now such that there are at least twelve pairs of rollers on the running meter. Accordingly, the roller diameters have also been reduced to such an extent that they stand that small gap. allow.
