A filament winder of the automatic exchange type in which chucks are brought successively into winding positions relative to a friction drive roller and thread is transferred from a package on an outgoing chuck to a bobbin on an incomming chuck. Each chuck moves along its own predetermined path towards and away from the friction drive roller. A free thread length is created between the friction drive roller and the outgoing chuck and this free thread length is intercepted by thread catching means on the incoming chuck.

The circumferential wall of the godet drum is heated via air which is heated by a heating device within the chamber of the drum. Air circulation through a closed path is aided by means of fan blades which are mounted on an interior face of the drum.
