Die Erfindung betrifft eine Einrichtung zum Kräuseln von Metallfäden und besteht darin, daß die einzelnen Kräuselungen durch nacheinander in Tätigkeit tretende Klemmbacken von oben nach unten gebildet werden. Die Klemmbacken sitzen an Hebeln, die paarweise gegeneinander bewegt werden und übereinander angeordnet sind; sie werden zweckmäßig nacheinander so geschlossen, daß die vorhergehenden Backen in der geschlossenen Stellung gehalten werden, während die folgenden sich schließen, so daß nach Beendigung der Kräuselung sämtliche Backen gleichzeitig geschlossen sind. Die Hebel sind zweiarmige und tragen an dem einen Ende die eigentlichen Klemmbacken aus feuerfestem Material, an dem anderen Ende werden sie angetrieben, z. B. durch Exzenterscheiben. Die Exzenterwelle geht durch den Boden der Formierungsglocke hindurch; ihr Lager ist luftdicht gegen den Boden abgeschlossen, während außen ein Handgriff zum Drehen angeordnet ist. Vorteilhaft werden die einzelnen Backenhebel bügeiförmig ausgebildet, damit das freie Fadenende beim Kräuseln unbehindert hin und her schwingen kann.The invention relates to a device for crimping metal threads and consists in that the individual crimps by successively coming into action clamping jaws be formed from top to bottom. The jaws sit on levers, in pairs are moved against each other and are arranged one above the other; they become functional successively closed so that the previous jaws are in the closed position be held while the following close, so that after the crimp is complete all jaws are closed at the same time. The levers are two-armed and carry at one end the actual clamping jaws made of refractory material, at the other end they are driven, e.g. B. by eccentric discs. The eccentric shaft goes through the bottom of the formation bell through; their storage is hermetically sealed against the floor, while the outside is a handle is arranged to rotate. The individual jaw levers are advantageously bow-shaped designed so that the free end of the thread swing back and forth unhindered when crimping can.

Die Backen sitzen an zweiarmigen, um Achsen 8, 8 drehbaren Hebeln; die Achsen 8, 8 sind in dem auf dem Glockenboden 9 befestigten Ständer 10 gelagert. Die oberen Enden der Backenhebel tragen die eigentlichen Kräuselungswerkzeuge, bestehend aus Platten 11 aus feuerfestem Material, die auswechselbar angeordnet sind, um sie ersetzen zu können. Damit die Platten 11, 11 nacheinander zur Einwirkung kommen, erhalten die unteren, zweckmäßig gekröpften Arme der Backenhebel Nasen 12, auf welche entsprechend gestaltete Exzenterscheiben 13 einwirken. Die wirksamen Flächen 14 der Exzenterscheiben 13 haben eine solche Länge und sind so zueinander gestellt, daß zunächst das oberste Backenpaar, dann das folgende usw. nacheinander geschlossen wird. Deshalb hat das unterste Exzenter 13 die längste wirksame Fläche 14, während die darüber liegenden wirksamen Flächen an Umfangslänge abnehmen.7, 7, the number of which varies according to the number desired Corrects ripples. The jaws sit on two-armed, rotatable about axes 8, 8 To leverage; the axes 8, 8 are in the stand attached to the bell bottom 9 10 stored. The upper ends of the jaw levers carry the actual crimping tools, consisting of plates 11 made of refractory material, which are arranged interchangeably are to be able to replace them. So that the plates 11, 11 one after the other to act come, the lower, appropriately cranked arms of the jaw lever get noses 12, on which correspondingly designed eccentric disks 13 act. The effective areas 14 of the eccentric disks 13 have such a length and are placed in relation to one another that initially the top pair of jaws, then the following, etc. is closed one after the other. Therefore, the lowermost eccentric 13 has the longest effective surface 14, while the one above Reduce the circumferential length of the effective surfaces lying down.

Claims

Arms of the jaw lever attached by springs 15 to arms 16 which are seated on the stand 10, so that the jaw levers automatically return to their initial position. The eccentrics sit on a shaft 17 which is hermetically sealed in the bell base by a cone 18. At the lower end, the axle carries a handle 19, by means of which the eccentrics for opening and closing the jaws are moved back and forth. Since the free end of the thread to be crimped swings back and forth during the crimping, the jaw levers are designed in the shape of a bow (FIG. 3) so that the free end of the thread can enter the bow opening 20. The operation of the device is as follows: The thread F to be crimped is suspended by means of a clamp K in such a way that the length of the thread to be crimped hangs freely between the plates 11. Then the current is sent through the thread, and while it is still in the sintering glow heat, the hand lever 19 is slowly moved in the direction in which the effective surface 14 of the lowermost eccentric disc 13 acts on the nose 12 of the jaw lever, which the top plate 11 carries. As the lever 19 continues to rotate, the effective surface 14 of the eccentric located above it acts on the nose of the second jaw lever, etc. The jaw levers remain closed, so that after the movement of the last pair of jaws, all jaws are closed (FIG. 5). During the crimping process, the lower free end of the thread F swings back and forth and enters the temple opening 20. Pate ν T-A ν Proverbs:

1. Device for crimping metal filaments, characterized in that the individual crimps by successively operating clamping jaws one after the other be formed from top to bottom.

2. Apparatus according to claim 1, characterized characterized in that the clamping jaws are arranged one above the other and in pairs and are closed one after the other so that the previous jaws are held in the closed position while the following close, so that when the crimping is complete, all the jaws are closed at the same time.

3. Apparatus according to claim 1, characterized in that the jaws as two-armed Levers are formed, which at one end the actual crimping tool made of refractory material (e.g. Slate, clay, soapstone or the like) carry, while the other ends of eccentric discs driven one after the other.

4. Apparatus according to claim 1, characterized in that the lower arms of the Cheek levers carry lugs on which act successively eccentric disks, their effective surfaces decrease in length, so that the first acting eccentric the longest, the last acting has the shortest effective area.

5. Apparatus according to claim 1, characterized in that the jaw levers are bow-shaped so that the free The end of the thread to be crimped can swing freely back and forth.
