Zusammenfassung:The device is for winding shaped coil springs and has a frame-fitted spindle with a mandrel, which is connected with a turning drive. Application rollers press the spring onto the mandrel. The mandrel has a helical shape which corresponds to the internal shape of the cross-section of the spring and the pitch of the generated winding. It is mounted so that it can move axially. A copying roller is rigidly connected with the application rollers in the direction of the axis of the mandrel. This copying roller acts with the helical profile of the mandrel and is arranged at a distance from the rollers which represents a multiple of the pitch of the windings of the mandrel. L'INVENTION CONCERNE LES CONSTRUCTIONS MECANIQUES.LE DISPOSITIF FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QUE LE MANDRIN 3 PRESENTE UN PROFIL SPIRAL CORRESPONDANT AU PROFIL DE LA SECTION TRANSVERSALE DU RESSORT EN SERPENTIN ET DONT LE PAS CORRESPONDANT A CELUI DE LA SPIRALE A OBTENIR, ET EST MONTE AVEC POSSIBILITE DE DEPLACEMENT EN TRANSLATION AXIALE, ET EN CE QU'IL COMPORTE AU MOINS UN GALET-GABARIT 17 RIGIDEMENT SOLIDAIRE DES GALETS DE PRESSION 14, SOLLICITE AVEC CES DERNIERS VERS L'AXE DU MANDRIN DE MANIERE A COOPERER AVEC LE PROFIL SPIRAL DU MANDRIN, LEDIT GALET-GABARIT ETANT MONTE, PAR RAPPORT AUXDITS GALETS DE PRESSION, A UNE DISTANCE MULTIPLE DU PAS DES SPIRES DU MANDRIN.L'INVENTION PERMET NOTAMMENT D'OBTENIR DES SPIRALES SANS ECRASEMENT NI DEFORMATION DES SPIRES.
