## Abstract

A filament winding device (100) comprising a liner support device (42) supporting a liner (1), and a hoop winding device (43) that winds a fiber bundle (F) on to the outer peripheral surface (1S) of the liner (1) by rotating centered around the liner (1). The filament winding device (100) is characterized by being capable of simultaneously transporting the liner (1) and the hoop winding device (43), by having the liner support device (42) and the hoop winding device (43) arranged upon a trolley (40A), and moving the trolley (40A).

## Claims

### Claim 1

A filament winding device comprising:
a liner support device supporting a liner; and
a hoop winding device that winds a fiber bundle on to an outer peripheral surface of the liner by rotating centered around the liner,
wherein the filament winding device is capable of simultaneously transporting the liner and the hoop winding device, by having the liner support device and the hoop winding device arranged upon a trolley, and moving the trolley.

### Claim 2 (depends on 1)

The filament winding device according to claim 1, wherein the filament winding device is capable of simultaneously exchanging the liner and the hoop winding device, by having at least two trolleys placed on rails, and moving the trolleys.

### Claim 3 (depends on 2)

The filament winding device according to claim 2, wherein a work space for carrying out exchanging work of a bobbin in which the fiber bundles have been wound and the liner is provided in a vicinity of the rails.

### Claim 4 (depends on 1)

The filament winding device according to claim 1 comprising:
a liner shaft supported by the liner support device in such a condition that the liner shaft is attached to the liner; and
a liner transfer device which is configured to be connected to/separated from the liner shaft, wherein
the trolley is movable in such a condition that the liner shaft is separated from the liner transfer device.

### Claim 5 (depends on 4)

The filament winding device according to claim 4, wherein
when the liner shaft is supported by the liner support device, the liner transfer device is separated from the liner shaft, and
when the liner transfer device is connected to the liner shaft, the liner support device is separated from the liner shaft.
