Abstract (en)
[origin: EP0798058A2] The coil winding machine has a wire feed to supply wire to the winding heads and a cutter (38) which cuts off each coil length. The cutter is driven by a rapid action hydraulic cylinder (80) controlled by a programmable numerically controlled valve (78). The cutting action includes movable supports for the cutting system. These may be used to optimise the working stroke of the tool and to reduce the cutting noise or vibration.
