The invention relates to a method and a device for melt spinning, treating and winding a synthetic thread. The thread is pulled off, guided and treated after melt spinning by a treatment device and is wound onto a coil by a winding device. Said thread is guided vertically from the melt spinning process to the winding process over several levels. In order to maintain short operating times, in particular when the process is started or interrupted, the treatment device is operated from a first upper operational platform. The winding device is operated in a second lower operating platform. The thread is monitored in a transitional area between the treatment device and the winding device by means of a thread monitor.
