Description
Verfahren zur Herstellung kordelartiger Ketten. Die Erfindung betrifft ein Verfahren zur Verstellung kordelartiger Ketten, insbesondere für Schmuckzwecke.Process for the production of cord-like chains. The invention relates to a method for adjusting cord-like chains, especially for jewelry purposes.
Zur Herstellung der Kordelketten bekannter Art werden Drahtringe maschinell oder von Hand derart versetzt aneinandergereiht, <lgß ein zwei Schraubengänge bildendes Kordelgebilde entsteht.Wire rings are used to manufacture the cord chains of the known type or strung together by hand in such a way, <lgß a two screw threads forming cord structure is created.
Da die Herstellung von Hand sehr mühsam und teuer ist, sind Sondermaschinen gebaut worden, welche aber außer hohen Anschaffungskosten auch sorgsamer Überwachung durch gelernte Arbeitskräfte bedürfen.Since the production by hand is very laborious and expensive, special machines are used been built, but which, in addition to high acquisition costs, also requires careful monitoring by skilled workers.
Diese Nachteile werden durch den Erfindungsgegenstand beseitigt.These disadvantages are eliminated by the subject matter of the invention.
Das neue Verfahren besteht darin, daß eine Ein- oder Mehrfachankerkette zuerst in bekannter Weise durch Verdrehen zu einer Panzerkette umgebildet und die letztere alsdann weiter verdreht wird, bis sich steile, doppelgängige Verwindungen zeigen, in welche je ein Drahtstrang, beispielsweise aus weichem Eisen, eingelegt und nun das Gesamtgebilde abermals weiter verdreht wird, bis die Verwindungen geschlossen sind, d. h. zwischen derjenigen der Kette nur noch die der eingeklemmten Drahtstränge liegen, die nun in geeigneter Weise, beispielsweise durch Auflösen in Säure oder Ausziehen, entfernt werden.The new method is that a single or multiple anchor chain first transformed into a curb chain in a known manner by twisting and the the latter is then twisted further until there are steep, double-twisted twists show in which a wire strand, for example made of soft iron, is inserted and now the entire structure is twisted again until the twists are closed are, d. H. between that of the chain only that of the jammed wire strands are now in a suitable manner, for example by dissolving in acid or Take off, be removed.
Wird allgemein eine Panzerkette »überpanzert«, d. h. mehr verdreht, als zur Bildung der Panzerung erforderlich ist, so bleiben steile, doppelgängige Verwindungen stehen. Die Anzahl derselben kann durch weiteres Verdrehen vermehrt werden. Dabei aber tritt der Nachteil auf, daß sie an manchen Stellen der verdrehten Kette bereits ganz aufeinandergerückt, an anderen hingegen noch steil und offen sind. Ein derart ungleichmäßiges Gebilde ist unbrauchbar, es wirkt nicht allein unschön, sondern ist an denjenigen Stellen, die bereits geschlossene Verwindungen aufweisen, völlig steif. Sollten etwa durch weiteres Verdrehen auch die noch offenen Verwindungen den anderen gleich gebildet werden, so bricht die Kette, bevor dies erreicht ist, an einer bereits steif gewordenen Stelle ab.If an armored chain is generally "armored", i. H. more twisted, than is necessary for the formation of the armor, there remain steep, double-threaded ones Twists. The number of these can be increased by further turning will. But this has the disadvantage that they are twisted in some places The chain has already moved closer together, but on others it is still steep and open are. Such an uneven structure is useless, it does not work alone ugly, but is in those places that have already closed twists exhibit, completely stiff. Should also the still open ones by further turning If torsions are formed in the same way as the others, the chain breaks before this is reached, at a point that has already become stiff.
Es hat sich nun in überraschender Weise gezeigt, daß durch Einlegen von weichen Drahtsträngen in die bereits im Anfange des PÜberpanzernscc entstandenen, noch steilen Gänge der Verwindungen der Abstand der letzteren beim weiteren Verdrehen derart.geregelt wird, daß eine völlig gleichmäßig verwundene und nach dem Entfernen der Drahtstränge gut biegsame, kordelartige Kette entsteht.It has now been shown in a surprising way that by inserting from soft wire strands to those already created in the beginning of the PÜberpanzernscc, even steep courses of the twists, the distance between the latter as the twisting continues Such.reguled is that a completely evenly twisted and after removal the wire strands create a flexible, cord-like chain.
Das Einlegen der Drahtstränge wie auch das Verwinden kann von Hand oder maschinell ausgeführt werden.The insertion of the wire strands as well as the twisting can be done by hand or carried out by machine.
Es ist vorteilhaft, das Verwinden nicht fortlaufend vorzunehmen, sondern die Kette einschließlich der eingewundenen Drahtstränge mindestens einmal auszuglühen.It is advantageous not to do the twisting continuously, but instead anneal the chain including the twisted wire strands at least once.
