Summary:A machine for winding electrical coils from thin strip or ribbon, having a spindle on which the conductor is wound. A welding device welds intermediate or final terminations to the strip with predetermined spacing. The welding unit is mounted movably in relation to the winding spindle. Means are provided for precisely rotating the winding spindle and consistently stopping it at a fixed position. Means are provided for measuring precisely the length of one turn or known portion thereof so as to locate and weld the connection at a point that will cause it to fall in the required place when the connection has been wound onto the coil.
