Description

Webstuhlkarte Die Karten für Webstühle, insbesondere Jaquardmaschinen, sind bislang in der Hauptsache aus Papier gemacht worden. Solche Schablonen sind aber zufolge der geringen Festigkeit des Papiers den an sie gestellten Beanspruchungen nicht gewachsen, sondern zerreißen häufig, wodurch Betriebsstörungen eintreten.Loom card The cards for looms, especially jacquard machines, have so far mainly been made of paper. Such templates are but due to the low strength of the paper, the stresses placed on it not grown, but often tear, causing operational disruptions.

Es ist bereits bekannt, zwecks Erhöhung der Festigkeit von Papier und anderen Cellulosefaserstoffen, beispielsweise Pappe, Filz oder auch zerfasertes Material, diese mit Kondensationsprodukten aus einwertigen Phenolen und Formaldehyden zu durchtränken. Die so erhaltenen Erzeugnisse zeigen jedoch außer ihrer Härte eine überaus große Sprödigkeit, ein Nachteil, der diese Stoffe zur Herstellung des Gegenstandes gemäß der Erfindung ungeeignet macht.It is already known to increase the strength of paper and other cellulosic fibers, for example cardboard, felt or shredded Material, these with condensation products from monohydric phenols and formaldehyde to soak. However, the products thus obtained show one other than their hardness extremely great brittleness, a disadvantage of these substances for the manufacture of the object makes unsuitable according to the invention.

Zur Vermeidung dieser Nachteile werden erfindungsgemäß derartige Karten aus Faserstoffbahnen verfertigt, die mit einem Kondensationsprodukt von Aldehyden und mehrwertigen Phenolen oder deren Homologen verklebt sind. Dieses Klebemittel ist ausgezeichnet durch die Fähigkeit, nach kurzer Wärmebehandlung bereits zu erhärten. Beispielsweise werden Kondensationsprodukte aus Resorzin und Paraformaldehyd verwendet. Es können auch neben den Phenolen andere aromatische Körper zur Kondensation Verwendung finden, insbesondere auch solche, die eine N H.- oder N H-Gruppe enthalten. Auch andere Stoffe, die solche Gruppen enthalten, können verwendet werden, z. B. Harnstoff.In order to avoid these disadvantages, according to the invention, such cards are produced from fibrous webs which are glued to a condensation product of aldehydes and polyhydric phenols or their homologues. This adhesive is distinguished by its ability to harden after a short heat treatment. For example, condensation products made from resorcinol and paraformaldehyde are used. In addition to the phenols, other aromatic bodies can also be used for the condensation, in particular also those which contain an NH or NH group. Other substances containing such groups can also be used, e.g. B. urea.

Mit Hilfe derartiger Kondensationsprodukte gelingt es, Hartpapierkarten für Webstühle zu kleben und vor, während oder nach der Herstellung der Karten durch Druckeinwirkung bei Erwärmen auf ungefähr i 5o° C, welches nur ungefähr 1!. Minute zu dauern braucht, das Klebemittel in den erhärteten Zustand überzuf ühren.With the help of such condensation products it is possible to produce hard paper cards for looms to glue and before, during or after making the cards through Pressure applied when heated to about 150 ° C, which is only about 1 !. minute needs to take to transfer the adhesive to the hardened state.

Karten dieser Art entsprechen allen Anforderungen, die zufolge ihres Venvendungszwekkes an sie gestellt werden müssen. Die Karten sind biegsam und fest, so daß ein Brechen oder Zerreißen, wie dies oft bei Pappkarten vorkommt, vermieden wird.Cards of this type meet all the requirements of theirs Purposes of use must be made to them. The cards are flexible and strong, so that breaking or tearing, as often happens with cardboard cards, is avoided will.
