  • Filament winding machine
    Patent number: 4524918
    Abstract: 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.
