Description

Für Kofferwandungen bestimmte Platte mit Stäben Zusatz zum Patent 689 459 Gegenstand der Erfindung ist eine Abänderung und Verbesserung der für Kofferwandungen bestimmten Platte mit Stäben nach Patent 689459, bei der eine Einlage aus Wellpappe benutzt ist. ES hat sich nun gezeigt, daß die Wellpappe, die ja nur aus miteinander verklebten Fasern besteht, sich bei zu starker Biegung auflöst, dergestalt, daß -sie in zwei voneinalader getrennte Schichten zerfällt. Dies ist darauf zurückzuführen, daß .die Oberfläche der Wellpappe mit dem Klebstoff bzw. dem Füllstoff eine innige Bindung eingeht, deren Festigkeit erheblich größer ist als die innere Festigkeit des Werkstoffes, aus dem die Wellpappe hergestellt ist.Plate with rods intended for suitcase walls, addition to patent 689 459. The subject of the invention is a modification and improvement of the plate with rods intended for suitcase walls according to Patent 689459, in which an insert made of corrugated cardboard is used. It has now been shown that the corrugated cardboard, which consists only of fibers glued together, dissolves if it is bent too much, in such a way that it breaks up into two separate layers. This is due to the fact that the surface of the corrugated cardboard enters into an intimate bond with the adhesive or filler, the strength of which is considerably greater than the internal strength of the material from which the corrugated cardboard is made.

.Um diesen Mangel zu beheben, wird gemäß des Erfindung an Stelle der Wellpappe ein in die gleiche Form gebrachtes Gazegewebe benutzt. Ein derartiges Gewebe hat den Vorteil, d,aß seinerseits seine Zerreißfestigkeit wesentlich höher ist, andererseits dringt das Bindemittel bzw. der Füllstoff in die Maschen des Gazegewebes ein, so daßeine innige Verbindung der zu beiden Seiten der Gaze liegepiden Decklagen stattfindet. Man k= infolgedessen die Platte rollen und biegen, bis nahe an die äußerste Zerreißgrenze der Gaze, ohne daß -die Gefahr besteht, daß die Stäbe bzw. der Füllstoff und das Bindemittel sich von der Gaze löst..To remedy this deficiency, according to the invention, instead of the Corrugated cardboard uses a gauze fabric that has been shaped in the same way. Such a thing Tissue has the advantage that its tensile strength is much higher is, on the other hand, the binding agent or filler penetrates into the mesh of the gauze fabric so that an intimate connection of the cover layers lying on both sides of the gauze takes place. Man k = as a result roll and bend the plate until it is close to the extreme tensile strength of the gauze without the risk of the rods or the filler and binder will separate from the gauze.
