The roller 30 includes a first roller part 31 that presses the pressing target M in a radial direction of the roller 30 and a second roller part 32 that protrudes further than the first roller part 31 in the radial direction on each side of the first roller part 31 in an axial direction of the roller 30 to make contact with the pressing target M in the axial direction. Each of the second roller parts 32 has an elastic member E2 at least in a portion in contact with the pressing target M.

Abstract: A reinforcement layer of a high-pressure vessel has a plurality of low helical layers. In at least one of the (i?1)-th low helical layer and the i-th low helical layer, the difference between the diameter of an opening formed in an end portion of the (i?1)-th low helical layer and the diameter of an opening formed in an end portion of the i-th low helical layer is equal to or larger than the width of the band-shaped fiber when an inclination angle WA of the band-shaped fiber is equal to or smaller than a second angle smaller than a first angle.

Abstract: A winding section of a filament winding apparatus winds a fiber bundle around a filament-wound member. A tension acquisition part acquires a detected winding-tension value. A supply-speed acquisition part acquires a detected supply-speed value. A storage part stores correlation information in which an allowable determination range of winding tension is set in relation to the supply speed. A determination part determines whether the winding of the fiber bundle is successful or unsuccessful by comparing detected-value information, including the detected winding-tension value and the detected supply-speed value associated with each other, with the correlation information.

Abstract: A filament winding apparatus winds, around a workpiece, a fiber bundle formed by bundling a plurality of fibers. The filament winding apparatus includes a widening roller that rotates while making contact with the fiber bundle that is being conveyed. The widening roller has, provided on the peripheral surface, a plurality of projecting ridges extending in the axial direction, the projecting ridges being arranged side by side in the circumferential direction. The projecting ridges make contact with the fiber bundle to thereby widen the fiber bundle.

Abstract: A high pressure tank production apparatus includes a feeder for feeding reinforced fibers wound around a resin liner and a near infrared ray radiation unit inserted into the resin liner to radiate near infrared rays. The reinforced fibers wound around the resin liner absorb near infrared rays radiated from the radiate near infrared ray radiation unit by a near infrared absorber contained in the reinforced fibers. As a result, an outer layer made of fiber reinforced resin is formed to cover the resin liner.
