A device for removing a winding of an electric linear motor which winding is arranged in downwardly open grooves of a bundle of laminations fastened to a support. The individual strands of the winding are held fast in the grooves on holders. The holders have feet with webs which extend out of the grooves, the feet engaging in mounted position in undercuts in the grooves. The device includes at least one removal device arranged on a vehicle which is moveable on the support, the device having at least one pressing tool and at least one pulling tool coupled with it. The pressing tool has two bevels extending in V-shape to each other which are intended to come against the webs of the feet, by which bevels, upon the downward movement of the removal device, every two webs present on opposite sides of the holder are pressed towards each other. The pulling tool includes of two hooks which hook resiliently on both ends of the holder in the final position of the pressing tool in which the feet of the holder are free of the undercuts of the grooves. Thereby, the holder is fixed on the removal device and upon the downward movement thereof is pulled out of the groove together with the corresponding strand of the winding.

ispositif pour enlever un bobinage d'un moteur électrique linéaire, lequel bobinage est disposé dans les rainures ouvertes vers le bas d'un faisceau de tôles fixées à un support. Chaque fil du bobinage est assujetti dans les rainures sur des montures. Les montures ont des pieds avec des âmes qui s'étendent à l'extérieur des rainures, les pieds s'engageant en position montée dans des entailles ménagées dans les rainures. Le dispositif comprend au moins un dispositif d'enlèvement installé sur un véhicule pouvant se déplacer sur le support, le dispositif étant muni d'au moins un outil de pression et d'au moins un outil de tirage qui lui est accouplé. L'outil de pression a deux biseaux formant un V qui viennent se placer contre les pieds des âmes et qui, lors du mouvement vers le bas du dispositif d'enlèvement, poussent l'une vers l'autre les deux âmes se trouvant de chaque côté de la monture. L'outil de tirage comporte deux crochets qui s'accrochent de façon souple aux deux bouts de la monture dans la position finale de l'outil de pression dans laquelle les pieds de la monture sont dégagés des entailles des rainures. Ainsi, la monture est fixée au dispositif d'enlèvement et, lors du mouvement vers le bas de celui-ci, elle est tirée hors de la rainure avec le fil correspondant du bobinage.
