A method of measuring the thickness of a fiber texture wound on an impregnation mandrel for fabricating an annular structural part of a turbine engine out of composite material, the method including, prior to winding the fiber texture, acquiring a reference distance between an outside surface of the impregnation mandrel and a distance sensor positioned facing the outside surface of the impregnation mandrel, while winding the fiber texture, acquiring at least one real distance between the distance sensor and the outside surface of the fiber texture wound on the impregnation mandrel, and calculating the real thickness of the fiber texture wound on the impregnation mandrel by subtracting the real distance from the reference distance.

A tank production system and method that can suppress peeling of normally wound fibers when fibers not wound at predetermined position are peeled off. The system includes a rotation unit that rotates a liner, a storage unit that has recorded thereon the number of revolutions of the liner, and a detection unit that detects abnormality in the position of the fibers wound on the outer periphery of the liner. The rotation unit, when abnormality in the position of the fibers is detected by the detection unit, refers to the number of revolutions of the liner recorded on the storage unit and rotates the liner in an opposite direction to the direction in which the fibers are wound, back to the number of revolutions of the liner at a point when the winding of fibers to form a fiber layer, which includes the fibers detected at the abnormal position, has started.

A filament winding system includes a storage unit that stores in advance a reference shape of a winding object, and winding conditions including a winding position and a winding angle at which a fiber is wound around the winding object having the reference shape, a guide that is movable relative to the winding object, and feeds the fiber onto the winding object, a rotating device that rotates the winding object, such that the fiber fed from the guide is wound around the winding object, a measuring unit that measures a shape of the winding object, and a controller. When there is a difference between the reference shape stored in the storage unit, and the measured shape of the winding object, the controller corrects the winding conditions so as to reduce or eliminate the difference, and controls the guide according to the corrected conditions.

Disclosed is a liner reel, a cassette, a let off station and a method for collecting a liner, wherein the liner reel has a core and a shell that is concentrically mountable to said core for rotation together with said core about a liner reel axis, wherein the shell has a collection wall that extends in a circumferential direction about the liner reel axis when the shell is mounted to the core, wherein the collection wall is arranged for receiving the liner, wherein the core has a support wall extending in the circumferential direction for supporting the collection wall at least with a vector component in a radial direction perpendicular to the liner reel axis, wherein the collection wall is at least partially contractible in said radial direction when the shell is removed from the core.

Apparatus and method for manufacturing coil screens. The apparatus includes at least one winding device, arranged above a working surface, that is structured for producing coils; a depositing device structured and arranged to deposit the coils on the working surface; and a storage device arranged, with respect to a depositing direction of the coils, downstream from the at least one winding device.

It is possible to achieve reduction in the occurrence of tension decrease at fiber bundles in a sheet. A method of manufacturing a tank includes: a feed step of feeding a sheet including aligned fiber bundles while applying tension to the sheet in the longitudinal directions of the fiber bundles; a detection step of detecting a decreased tension part subjected to tension decrease in the sheet being fed; a tension recovery step of compensating for the tension decrease at the decreased tension part by spraying an organic solvent if the decreased tension part is detected in the detection step; and a winding step of winding the sheet having been fed on a liner.

A filament winding apparatus includes a controller that controls the action of the filament winding apparatus. The controller includes a tension controller that controls a tension adjuster in such a way that an adjusted tension waveform that relates the rotation phase of a liner to the tension of a fiber adjusted by the tension adjuster has a phase opposite to the phase of a temporary tension waveform.

A system and a method of manufacturing continuous glass filament fiberglass media comprises melting glass within a temperature controlled melter. Molten glass exits through a bushing plate with orifices of varying row configurations and orientations. The resulting fiberglass filaments are received on a rotating drum and sprayed with resin and aqueous solution. The resulting fiberglass mat is placed onto a let-off table then sprayed with aqueous solution before further processing.
