Description
Rollbares Sperrholz Die Erfindung betrifft. rollbares Sperrholz, das z. B. für Rolläden Verwendung findet, deren Schauseite aus :einem Holzfurnier besteht, auf dessen Rückseite Leisten zur Versstärkung angeordnet sind. Im Gegensatz zu bekannten Rolläden dieser Art sind nach der Erfindung unmittelbar auf - das Furnierholz quer zur Faser mit geringem Abstand voneinander Leisten geleimt, wobei als Furnier vorteilhaft ein gerade und schlicht gewachsenes Furnier verwendet wird.Rollable Plywood The invention relates to. rollable plywood that z. B. is used for roller shutters, the front side of which consists of: a wood veneer, on the back of which strips are arranged for reinforcement. In contrast to well-known Shutters of this type are according to the invention directly on - the plywood across Glued strips to the fiber with a small distance from each other, which is advantageous as a veneer a straight and simply grown veneer is used.
Es ist bekannt, Rollwände in der Weise herzustellen, daß Furnierholz mit Stäbchen verbunden wird. Hierbei verlief jedoch die Faser des Furnierholzes parallel mit den Stäb,-chen und dementsprechend senkrecht zur Rollrichtung. Auch war zwischen die Stäb,-chen und das Furnierholz meist ein Textilstoff geklebt. Es ist ferner auch bekannt, hierbei Furnierholz aus einem zusammenhängenden und fugenlosen Stück zu verwenden. Demgegenüber hat das rollbare Sperrholz nach der Erfindung den Vorteil, daß kein Textilstoff benötigt wird, ferner die Fläche des Furnierholzes vollkommen zusammenhängt und die aus dem Sperrholz hergestellten Roll;-wände außerordentlich widerstandsfähiggegen mechanische und physikalische: Einwirkungen, wie Temperaturschw.ankimgen und Eintrocknung, sind.It is known to manufacture roll walls in such a way that plywood connected with chopsticks. Here, however, the grain of the veneer ran parallel to the chopsticks and accordingly perpendicular to the direction of rolling. Even A textile material was usually glued between the sticks and the veneer. It is also known, this veneer from a coherent and seamless Piece to use. In contrast, the rollable plywood according to the invention has the Advantage that no textile material is required, as well as the surface of the plywood perfectly connected and the roll-up walls made of plywood are extraordinary Resistant to mechanical and physical: influences such as temperature fluctuations and drying out, are.
Die Erfindung beruht auf der üb@errasc'henden Erkenntnis, daß es möglich ist, die Biegung- des Furnierholzes ohne die bisher übliche Verwendung von Textilstoff in der Faserrichtung vorzunehmen, ohne daß das Furnierholz dabei aufplatzt oder bricht.The invention is based on the surprising realization that it is possible is, the bending of the plywood without the usual use of textile material in the grain direction without the plywood cracking or breaks.
Im besonderen liegt der Querschnitt :der Leisten und ihr Abstand voneinander in der Größenordnung von 7 X i o und 2 mm. Bei Einhaltung dieser Maße ergeben sich Rollläden, die in besonders günstiger Weise die an solche Rolläden gestellten Anforderungen, wie Biegeradius, Haltbarkeit u. dgl., erfüllen. Für Sonderzwecke sind jedoch auch andere Abmessungen möglich, deren Verhältnis zueinander jedoch im wesentlichen das gleiche bleibt. Um ein Werfen des Furnierholzes unter allen Umständen zu verhindern, wird ferner die Leimschicht auf die Flächen beschränkt, an denen die Leisten auf dem Furnierholz. aufliegen. Es soll alsQP beim Aufleimen der Leisten auf das Furnier kein Leim auf die Flächen zwischen den Leisten gepreßt werden. Irgendein elastischer Werkstoff zwischen Furnier und Leisten ist nicht erforderlich. Zum Aufleimen wird, wie an sich bekannt, elastischer Leim verwendet.The cross-section lies in particular: the strips and their distance from one another on the order of 7 X i o and 2 mm. If these dimensions are adhered to, the result is Roller shutters that meet the requirements placed on such roller shutters in a particularly favorable manner, such as bending radius, durability and the like. For special purposes, however, are also other dimensions are possible, but their ratio to one another is essentially the same remains the same. To prevent the plywood from being thrown under any circumstances, Furthermore, the glue layer is limited to the areas where the strips are on the plywood. rest. It is intended as a QP when gluing the strips onto the veneer no glue is pressed onto the areas between the strips. Some elastic No material is required between the veneer and the strips. For gluing, as known per se, elastic glue is used.
Auf der Zeichnung ist ein Ausführungsbei spiel des Erfindungsgegenstandes dargestellt. Fig. i ist eine perspektivische Ansichteines geradeliegenden Rolladenteils.In the drawing, a Ausführungsbei is game of the subject invention shown. Fig. I is a perspective view of a straight roller shutter part.
Fig.2 zeigt in Stirnansicht einen Rolladen in der Biegestellung.2 shows a front view of a roller shutter in the bending position.
Auf die Furnierholztafel i von ungefähr i mm Stärke sind rechteckige Leisten unmittelbar geleimt, derart, daß zwischen den Leisten ein geringer Abstand gewahrt bleibt. An den dadurch auch an der Innenseite frei bleibenden Stellen des Furnierholzes i soll kein Leim vorhanden sein.On the veneer wood panel i approximately i mm thick are rectangular Last glued directly, in such a way that there is a small distance between the strips is preserved. In the areas of the Veneer i should not have any glue.
Beim Rollen (Fig. 2) stoßen die äußeren Kanten 3 der Leisten aneinander, während sich das Furnierholz an den freien Stellen biegt.When rolling (Fig. 2) the outer edges 3 of the strips abut each other, while the veneer bends in the free places.
Die Herstellung des rollbaren Sperrholzes erfolgt also ohne Zuhilfenahme eines biegsamen Werkstoffes, wie Leinwand, da die Leisten unmittelbar auf die Furnierholztafel, d. h. also Holz auf Holz quer zur Faserrichtung, geleimt sind.The rollable plywood is manufactured without any assistance a flexible material, such as canvas, because the strips are directly on the veneer wood panel, d. H. that is, wood on wood across the grain, are glued.
