Description
Verfahren zur Herstellung von Puppen für galvanische Trockenelemente Bei der Herstellung von galvanischen Trockenelementen werden die Preßlinge mit Wickelstoff bzw. Wickelpapier umwickelt, das durch Wickelzwirn fest um den Preßling gebunden wird. Die zu diesem Zweck verwendeten Wickelzwirne müssen einerseits reißfest genug sein, um die Preßlinge möglichst fest einwickeln zu können. Anderseits müssen sie den sonstigen Anforderungen in bezug auf äußere Beschaffenheit des Fadens, wie z. B. Glätte, Stärke, sowie auf chemische Eigenschaften, entsprechen. Man verwendet je nach den gestellten Anforderungen Flachs-, Hanf-, Baumwoll- und Ramiezwirne verschiedener Stärken. Vielfach nimmt man auch starke Zwirne, um dadurch zugleich die nötige Zentrierung des Preßlings im Zinkbecher zu sichern.Process for the production of dolls for galvanic dry elements In the manufacture of galvanic dry elements, the compacts are wrapped with wrapping material or wrapping paper wrapped tightly around the compact by winding thread will. The twisted threads used for this purpose must, on the one hand, be tear-resistant enough to be able to wrap the compacts as tightly as possible. On the other hand, they have to the other requirements with regard to the external nature of the thread, such as B. smoothness, strength and chemical properties. One uses Depending on the requirements, flax, hemp, cotton and ramie threads of different types Strengthen. In many cases, you also use strong threads in order to achieve the necessary centering at the same time to secure the pressed part in the zinc cup.
Man hat bis jetzt vergeblich versucht, die teuren Flachs-, Hanf- und Ramiezwirne in allen Fällen durch Baumwollzwirne zu ersetzen, da diese verschiedene wesentliche Nachteile haben. Selbst beste Baumwollzwirne haben in der Regel nicht die nötige Reißfestigkeit, sie sind zu ungleichmäßig oder rauh und faserig, was ein erheblicher qualitativer Nachteil ist. Außerdem quellen Baum-Wollgarne leicht, wenn sie im Element mit dem Elektrolyten zusammenkommen. Das Fasern ist besonders nachteilig, wenn mit Wickelmaschinen gewickelt wird. Es hat sich nun gezeigt, daß man eine allen technischen Anforderungen entsprechende und relativ billige Wicklung herstellen kann, wenn man zur Wicklung ein Material verwendet, das man durch Zusammenzwirnen von Baumwollgarnen mit Garnen aus Ramie, Flachs, Hanf o. dgl. erhält. Derartige Zwirne zeigen eine ausreichende Reißfestigkeit, der Zwirn ist glatt und die Möglichkeit des Quellens ist so weit ausgeschaltet, daß sie unberücksichtigt bleiben kann. Die Menge der einzelnen zur Herstellung des Wickelzwirnes verwendeten Garne kann je nach den Eigenschaften der Rohstoffe und den Anforderungen, die an den Wickelzwirn gestellt werden, in weiten Grenzen schwankend gewählt werden. Man kann erfindungsgemäß die Baumwollgarne auch zusammen mit mehreren anderen Garnen verarbeiten.Up until now you have tried in vain to buy the expensive flax, hemp and Replace ramie twine with cotton twine in all cases, as these are different have significant disadvantages. Even the best cotton threads usually do not have them the necessary tear resistance, they are too uneven or rough and fibrous, what is a significant qualitative disadvantage. In addition, tree wool yarns swell easily, when they come together in the element with the electrolyte. The fiber is special disadvantageous when winding with winding machines. It has now been shown that a relatively cheap winding that meets all technical requirements can be made by using a material for winding that is twisted together of cotton yarns with yarns from ramie, flax, hemp or the like. Such Twisted yarn shows sufficient tear strength, the twisted yarn is smooth and the possibility the swelling is so eliminated that it can be disregarded. the The amount of the individual yarns used to produce the twisted winding can vary according to the properties of the raw materials and the requirements placed on the winding thread can be chosen fluctuating within wide limits. You can according to the invention also process the cotton yarns together with several other yarns.
