发明名称 DEVICE FOR FORMING COILS OF METAL WIRE
摘要 According to this method, preformed turns (10) of the said wire are dropped into a forming pit (1) which has a substantially cylindrical wall with a vertical axis, where they are superposed in order to form a bobbin (7). As the turns (10) fall, a radial force of attraction towards the wall of the pit (1) is exerted on them, the direction of this force being stimulated by a movement of rotation about the axis of the pit. The attraction force is preferably generated by a rotating magnetic field. To this end, the device comprises means for exerting, on the turns (10), the said force stimulated by a rotational movement comprising inductors, such as electromagnets (5), uniformly distributed at the periphery of the pit and means for cyclically supplying these electromagnets with direct current. …<??>The invention applies to the forming of wire bobbins in magnetic metal, particularly steel. …<IMAGE>…
