In the inventive device, a wire (18) is guided by means of a wire guiding device (20) and is wound onto a shaped body (10) of a template (10, 12) which can be rotationally driven. Said shaped body (10) is provided with recesses (16). The wire is cyclically pressed into the recesses (16) during the rotation of the template (10, 12) by means of outer forming elements (12) which can be driven radially. The wave-shaped coil windings are then converted into longitudinal slits of a coil receiver (34) which is axially positioned in front of the forming body (10). Said coil receiver (34) is rotationally fixed in a substantial manner during the winding movements. The aim of the invention is to produce complete winding movements over the circumference in a simple manner. The end of the last winding of a wave winding is formed by means of an additional inwards movement of at least one forming element (12) when said last winding is placed in a swing angle position of the template (10, 12) that is different to the swing angle position in the cyclical forming movement in the allocated recess (16).
L'invention concerne un dispositif qui se caractérise en ce qu'un fil (18) acheminé jusqu'à un guide-fil (20) est enroulé sur un corps moulé (10) d'un gabarit (10, 12) qui peut être entraîné en rotation et est muni d'encoches (16) et peut être comprimé de manière cyclique dans les encoches (16) au cours de sa rotation, par des éléments moulés extérieurs à déplacement axial. Les spires de fil ondulées obtenues sont ensuite transférées dans la fente longitudinale d'un support de bobine (34) positionné dans le sens axial devant le corps moulé (10), ledit support étant maintenu sensiblement bloqué en rotation pendant le mouvement d'enroulement. Afin d'obtenir de manière aisée des enroulements ondulés complets sur la périphérie, il est prévu que l'extrémité de la dernière spire d'un enroulement ondulé soit formée suite à un mouvement supplémentaire d'au moins un des éléments moulés (12) dans une autre position d'angle de rotation du gabarit (10, 12) que celle adoptée lors du mouvement de formage effectué de manière cyclique dans l'encoche (16) associée.
