A roller unit aligns tapes in a width direction and feeds the aligned tapes. The tapes are made of fibers which have not been impregnated with resin or have been impregnated with the resin. The roller unit includes rollers and a support shaft. The rollers rotate by friction force between the tapes and the rollers when the rollers contact with the tapes. The rollers are aligned so that rotation axes of the rollers lie on a same straight line. Diameters of the rollers are same as each other. The support shaft supports the rollers rotatably at rotational speeds independent from each other.

A fiber width adjustment device is for adjusting a width of a tape made of fibers before or after being impregnated with resin. The tape is a material for a fiber reinforced plastic. The fiber width adjustment device includes a pair of wall surfaces, a moving mechanism and rollers. The pair of the wall surfaces form a path for passing the tape. The path has a gradually decreasing width. The moving mechanism is configured to move the path relatively to the tape so that a position at which the tape leaves the path changes. The rollers are for feeding the tape in the path.

A fiber feeding device includes rollers, a brake and a belt conveyor. The rollers guide feeding out of tapes. The tapes are arrayed without overlapping the tapes in a width direction. The brake stops first feeding out of a first tape. The belt conveyor feeds out second feeding out of a second tape. The second tape is guided by a selected roller. The second tape is fed out by being sandwiched between the selected roller and the belt conveyor. The selected roller approaches the belt conveyor to sandwich the second tape between the selected roller and the belt conveyor while a nonselected roller retreats from the belt conveyor to prevent a third tape from being sandwiched between the nonselected roller and the belt conveyor. The third tape is guided by the nonselected roller. The third tape includes the first tape.

A cargo receiving facility includes a net and a transport mechanism. The net is suspended among supports. The net is configured to receive a cargo dropped from an unmanned aircraft in flight. The transport mechanism is configured to transport the cargo received by the net. The net has an elasticity corresponding to a mass of the cargo. The net has openings each having a size corresponding to a pressure of down-wash from the unmanned aircraft.

According to one implementation, a prepreg lamination apparatus includes first and second rollers, a table, and a feed structure. The first roller sends out a first prepreg tape which is a part of material of an FRP. The second roller sends out a second prepreg tape which is another part of the material of the FRP. The table is for laminating the first and second prepreg tapes directly or indirectly. The feed structure is adapted to feed out the first and second prepreg tapes in a feeding direction by moving the first and second rollers relatively to the table while performing at least one of movement of the first roller relatively to the second roller, and rotation of at least one of the first and second rollers relatively to the table around an axis which is not parallel to each of rotation axes of the first and second rollers.

A composite manufacturing apparatus includes a width determining mechanism and a gas supplier. The width determining mechanism has a body and a gas passage. The body has a path configured to allow a tape material including fibers impregnated with a resin to pass therethrough. The path has a bottom surface and a pair of wall surfaces. The pair of the wall surfaces form a gap that gradually decreases. The gas passage is provided inside the body and formed by the bottom surface having a plurality of through holes, and is in communication with the plurality of through holes. The gas supplier is configured to supply gas to the gas pass age.
