A method for processing a strand-type fiber bundle includes sending the fiber bundle to an air nozzle of a pre-spinning machine used to produce roving. A twist is imparted to the fiber bundle via a vortex air current within the air nozzle to form the roving, wherein the roving leaves the air nozzle through an outlet and is deposited in a receptacle. Normal operation is interrupted in a stop phases during which roving is not produced by the air nozzle. A start-up phase is commenced between the stop phase and subsequent normal operation wherein the roving produced during the stop phase is discarded after leaving the air nozzle when quality of the roving does not meet a desired specification. The roving discharge is deactivated when the quality of the roving meets the desired specification and the roving removed by the roving discharge is separated from the roving.

A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.
