  Verfahren zur Herstellung von Kegelfedern aus Stahlbändern. 



   Den Gegenstand der Erfindung bildet ein Verfahren zur Herstellung von Kegelfedern aus Stahlbändern, das bezweckt, zu verhindern, dass der Querschnitt des Bandes nach dem 
 EMI1.1 
 die hohle Seite des Bandes dem Dorn zugekehrt ist. 



   Auf der Zeichnung veranschaulicht
Fig. 1 eine Seitenansicht des Stahlbandes vor dem Aufwickeln, ferner in   grösserem     Magstabe  
Fig.   2   einen Schnitt nach der Linie 2-2 der Fig. 1, von rechts gesehen, und
Fig.   8   die fertige Feder im Längsschnitte. 



   Zur Herstellung der Kegelfedern wird das Stahlband A (Fig.   t) verwendet,   dessen Querschnitt in der aus Fig. 2 ersichtlichen Weise an seinen beiden uach den Schmalseiten hin gelegenen Enden nach derselben Seite hin gekrümmt ist. Dieses Stahlband wird derart auf den Dorn aufgewickelt, dass seine hohle Seite dem Dorn zugekehrt ist. Hiebei wird das Band vollständig gerade, wie aus Fig. 3 ersichtlich ist.   Untr Umstanden   ist es vorteilhaft, den Querschnitt des Bandes nicht nur an den beiden Enden, sondern auf seiner ganzen Lange zu krümmen. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of conical springs from steel strips.



   The object of the invention forms a method for the production of conical springs from steel strips, the purpose of which is to prevent the cross-section of the strip after
 EMI1.1
 the hollow side of the tape faces the mandrel.



   Illustrated on the drawing
Fig. 1 is a side view of the steel strip before winding, also on a larger scale
FIG. 2 shows a section along line 2-2 of FIG. 1, seen from the right, and
8 shows the finished spring in longitudinal section.



   To produce the conical springs, the steel strip A (Fig. T) is used, the cross-section of which is curved towards the same side at its two ends located towards the narrow sides in the manner shown in FIG. This steel strip is wound onto the mandrel in such a way that its hollow side faces the mandrel. In doing so, the tape becomes completely straight, as can be seen from FIG. Under certain circumstances it is advantageous to curve the cross-section of the band not only at the two ends, but along its entire length.
