  • the holders have, at least on both ends, on sides opposite each other, resilient feet having webs which in mounted position protrude from the grooves;

    there are undercuts in the grooves, and the feet are engaged, in mounted position, in the undercuts in the grooves;

    the system comprisinga vehicle which is moveable on said support; and

    at least one removal device located on said vehicle, said at least one removal device having at least one pressing tool and at least one pulling tool coupled to the pressing tool, said at least one removal device being located in working position directly below the bundle of laminations and being moveable up and down perpendicular to a horizontal direction of movement of the vehicle;

    wherein the pressing tool has two bevels extending in V-shape relative to each other to contact all the webs of said holder;

    upon an upward movement of the removal device, two of the webs present on opposite sides of the holder are pressed towards each other by the bevels;

    said pulling tool comprises two hooks;

    in an end position of the pressing tool, the feet of the holder are set free of the undercuts of the grooves by the pressing tool, and the two hooks of the pulling tool engage with spring action on an end of the holder to secure the holder to the removal device; and
