Description
Vorrichtung zum gleichzeitigen Herstellen mehrerer Stahldraht- oder Stahlbandkopien nach einer magnetischen Schallaufzeichnung Der Erfindungsgegenstand gehört zur Klasse der Vorrichtungen zum gleichzeitigen Herstellen mehrerer Stahldraht- oder Stahlbandkopien nach einer Schallaufzeichnung, die in magnetischer Form auf einem Stahldraht oder Stahlband aufgetragen ist, vermittels eines Schallabnahme-Sprechkopfes und eines Kopiersprechkopfes.Device for the simultaneous production of several steel wire or Steel tape copies after a magnetic sound recording The subject of the invention belongs to the class of devices for the simultaneous production of several steel wire or steel tape copies after a sound recording that is in magnetic form a steel wire or steel band is applied by means of a sound pick-up headset and a copier speaking head.
Das Wesen der- Erfindung besteht darin, daß der Magnet des Kopiersprechkopfes der Anzahl der an ihm vorbeigeführten Kopierdrähte entsprechend breit gewählt und mit kammartigen Zähnen versehen ist.The essence of the invention is that the magnet of the copier speaking head chosen according to the number of copy wires passed by it and wide is provided with comb-like teeth.
Dadurch wird erreicht, daß mehrere gleichzeitig zu kopierende Stahlbänder dicht nebeneinander über dem Sprechkopf laufen und daß das zur Kopierung verwendete Magnetfeld des Sprechkopfes infolgedessen eine hohe Kraftliniendichte aufweisen kann, was für die exakte und getreue Kopierung wesentlich ist.This ensures that several steel strips to be copied at the same time run close to each other over the headset and that the one used for copying As a result, the magnetic field of the speaking head has a high density of force lines can do what is essential for exact and faithful copying.
In beispielsweiser Ausführungsform ist der Erfindungsgegenstand in der Zeichnung dargestellt.In an exemplary embodiment, the subject matter of the invention is shown in FIG shown in the drawing.
Gemäß der Zeichnung ist i die den bespielten (Aufnahme-) Draht 2 enthaltende Vorratsspule, 3 die zugeordnete Abwickelspule. Der Aufnahmedraht 2 erregt den Schallabnahmemagneten q., der über einen Verstärker 5 den eigentlichen Kopier-Elektromagneten 6 erregt. Der Kern dieses Elektromagneten ist als Kamm 7 ausgebildet mit engen nebeneinanderliegenden Kammzähnen (vgl. Abb.2). Es kann selbstverständlich zur Erzielung des erforderlichen magnetischen Schlusses auch noch ein zweiter Kamm 7, der die zu kopierenden Drähte von oben her umfaßt, über dem unteren Kamm 7 angeordnet sein, was in der Zeichnung nicht besonders dargestellt ist. Durch die Zahnlücken des oberen der Kämme 7 werden nun die einzelnen zu kopierenden Drähte 8 durch Führungsösen g, =o parallel hindurchgeführt. Zu diesem Zwecke laufen sie in den Führungsösen g, von den Vorratsrollen ausgehend, zusammen und von den Führungsösen =o zu den Aufwickelspulen =i auseinander. Die Aufwickelspulen =i sitzen gleichachsig auf der gemeinsamen, auch die Aufwickelspule des Aufnahmedrahtes tragenden Welle i2, die vom motorischen Getriebe aus mit der erforderlichen Geschwindigkeit in Umlauf gesetzt wird. Dadurch wird das gleichmäßige Durchziehen des Aufnahmedrahtes und sämtlicher Kopierdrähte durch die Kopiermaschine gesichert.According to the drawing, i is the one containing the recorded (recording) wire 2 Supply reel, 3 the associated supply reel. The pickup wire 2 excites the sound pickup magnet q., which excites the actual copier electromagnet 6 via an amplifier 5. The core of this electromagnet is designed as a comb 7 with close adjacent ones Comb teeth (see Fig. 2). It can of course be used to achieve the necessary Magnetic connection also has a second comb 7, which holds the wires to be copied from above, be arranged above the lower ridge 7, which is in the drawing is not specifically shown. Through the gaps between the teeth of the top of the combs 7 are Now the individual wires 8 to be copied are passed through guide eyes g, = o in parallel. For this purpose, they run in the guide eyes g, starting from the supply rolls, together and from the guide eyes = o to the take-up reels = i apart. the Take-up reels = i sit coaxially on the common, also the take-up reel of the take-up wire-bearing shaft i2, which is connected to the motorized gearbox with the required speed is put into circulation. This will make the uniform Pulling the pick-up wire and all copy wires through the copy machine secured.
