Description

Verfahren zur Herstellung vonoschalldämpfenden und wärmedichten Isoliermatten aus Papier, Pappe oder ähnlichen elastischen Werkstoffen mit aus dem Mattenwerkstoff herausgedrückten Ausbeulungen Bei der Herstellung von Isoliermatten besteht die Schwierigkeit, ein Material zu schaffen, das bei hinreichender Elastizität durch von außen einwirkende Kräfte bleibende Formveränderungen nicht erleidet.Process for the production of sound-absorbing and heat-proof insulating mats made of paper, cardboard or similar elastic materials with the mat material Depressed bulges In the production of insulating mats there is a Difficulty in creating a material that can withstand sufficient elasticity external forces do not suffer permanent changes in shape.

Die Aufgabe wird- dadurch gelöst, daß in dem Herstellungsgang von Isoliermatten nach Patent 636 898 -eine Bearbeitung eingeschoben wird, die eine Vordehnung entsprechend der zu erwartenden Beanspruchung schafft.The object is achieved in that in the production process of Insulating mats according to patent 636 898 -a processing is inserted, the one Creates pre-stretching according to the expected stress.

Nun bestehen bereits Matten aus Papier oder Pappenbahnen mit eingeprägten Vorsprüngen. Diese Vorsprünge bekommen aber durch den Arbeitsvorgang dieselbe Dichtigkeit wie das Ausgangsmaterial, besitzen also auch keine größere Elastizität.Now there are already mats made of paper or cardboard sheets with embossed ones Protrusions. However, these projections get the same tightness as a result of the working process like the starting material, they do not have any greater elasticity.

Bei den Matten, die durch die vorliegende Erfindung verbessert werden sollen, bestehen die Materialvorsprünge aus einem aufgelockerten Gefüge und erhalten dadurch gegenüber dem Ausgangsmaterial für Druckbeanspruchung eine erhöhte Nachgiebigkeit. Nun treten Fälle auf, bei denen eine gewisse Volumenbeständigkeit der Matten verlangt wird, so daß sie unter Druckbeanspruchung nur einen geringen Höhenverlust erleiden.In the mats improved by the present invention should, the material protrusions consist of a loosened structure and are preserved as a result, compared to the starting material for compressive stresses, it is more resilient. Now there are cases in which a certain volume stability of the mats is required so that they suffer only a slight loss of height under pressure.

Um' nun schädliche Veränderungen zu vermeiden, wird das Material, das nach der Auflockerung eine Form wie Fig. z zeigt, durch ein Walzenpaar oder zwischen zwei Platten entsprechend der zu erwartenden Belastung vorgeprellt. Die Vorsprünge nehmen dann die in Fig. -, dargestellte Form an und erleiden unter der Last.keine Höhenverringerung.In order to avoid damaging changes, the material is that after loosening a shape like Fig. Z shows, by a pair of rollers or bounced between two plates according to the expected load. the Projections then take on the shape shown in Fig. -, and suffer under the Load, no height reduction.
