Description

Verfahren zur Herstellung von Treibriemen, Seilen, Transportbändern u. dgl.Process for the production of drive belts, ropes, conveyor belts and the like

Zusatz zum Zusatzpatent 8303446 Im Patent 870 346 ist das Herstellungsverfahren von in ihren Eigenschaften verbesserten Treibriemen, Förderseilen, Transportbändern od. dgl. aus bestimmten partiellen Derivaten des Polyvinylalkohol-s beschrieben.Addition to additional patent 8303446 In patent 870 346 is the manufacturing process of drive belts, conveyor ropes, conveyor belts with improved properties or the like. Described from certain partial derivatives of polyvinyl alcohol-s.

Bei der weiteren Bearbeitung dieses Verfahrens wurde gefunden, daß das meistens etwas zu starke Dehnungsvermögen solcher Treibriemen usw. völlig befriedigend verringert und zugleich eine weitere Steigerung der Reiß- und Bruchfestigkeit dadurch herbeigeführt werden kann, daß man die Treibriemen u. dgl. derart auswalzt, beispielsweise durch eine oder mehrere Walzenpaare zieht. daß dabei ihre Dicke merklich verringert wird. Vorzugsweise arbeitet man auf eine erhebliche Verringerung der Dicke hin, beispielsweise von 5 auf 3 mm. Das Dehnungsvermögen läßt sich so jeder gegebenen Anforderung anpassen.In further processing this procedure it was found that the stretching capacity of such drive belts, etc., which is usually a little too strong, is completely satisfactory reduced and at the same time a further increase in tear and breaking strength it can be brought about that the drive belts and the like are rolled out in this way, for example pulls through one or more pairs of rollers. that their thickness is noticeably reduced will. It is preferable to work towards a significant reduction in thickness, for example from 5 to 3 mm. The elongation can be like this adapt to any given requirement.

Beispiel Eine 25- bis 3oo/oige wäßrige und gut entlüftete Lösung eines Polyv inylalkohols mit der Verseifungszahl von etwa ,4o wird auf- einer gebräuchlichen Filmgießmaschine zu einem endlosen Film beliebiger Dicke vergossen. Die so entstehenden endlosen Bänder werden dann von beispielsweise 5 auf 3mm Dicke ausgewalzt und anschließend auf Treibriemen verarbeitet.Example A 25 to 300% aqueous and well-vented solution of a Polyvinyl alcohol with a saponification number of around .40 is commonly used Film casting machine cast into an endless film of any thickness. The resulting endless strips are then rolled out from, for example, 5 to 3mm thickness and then processed on drive belts.
