Winding a rotor coil for a vehicle alternator on a WH-751 winding machine. Note that the tooling is designed to support the mechanically weak flanges of the bobbin. See www.coilwindingmachines.eu for more information.
You can't maintain perfect "layer" or "side by side" winding forever. Eventually, the manufacturing tolerances of the wire and plastic bobbin start to add up. You can see that the position of the wire as it is wound onto the bobbin actually gets a little in advance of the feeder head. By the ninth layer, the wire eventually jumps back to the flange. In this particular application it is not a problem - the wire just needs to fit into the space available.
