Various embodiments of the present disclosure provide a rotorcraft-assisted system and method for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system includes a modular multicopter, a storage and launch system, an anchor system, a flexible capture member, and an aircraft-landing structure. The multicopter is attachable to the fixed-wing aircraft to facilitate launching the fixed-wing aircraft into free, wing-borne flight. The storage and launch system is usable to store the multicopter (when disassembled) and to act as a launch mount for the fixed-wing aircraft by retaining the fixed-wing aircraft in a desired launch orientation. The anchor system is usable with the multicopter, the flexible capture member, and the aircraft-landing structure to retrieve the fixed-wing aircraft from free, wing-borne flight.

A sheet conveying device includes a conveying body, a pressing body, and an attracting device. The conveying body conveys a sheet. The pressing body presses the sheet to a circumferential surface of the conveying body at an upstream side from an operation start position at which an operation with respect to the sheet starts, in a sheet conveying direction. The attracting device sucks and attracts the sheet onto the conveying body. The attracting device includes an attracting unit having an attracting region extending shorter than a distance between the pressing body and the operation start position. The attracting unit rotate together with the conveying body.

A unit for applying first and second tabs, obtained from first and second webs, to a chassis web includes an applicator drum rotatable about an axis and including a main body. A plurality of carriers is movable between a lowered position close to the axis and a raised position away from the axis, each including a suction portion. A first carrier first suction and non-suction portions aligned along the axis. A second carrier includes second suction and non-suction portions aligned along the axis. The first suction portions alternate with the second non-suction portions and the first non-suction portions alternate with the second suction portions. A first system holds the first web on the applicator drum upstream of a cutting device. A second system holds the second web on the drum upstream of the cutting device.

A stacking apparatus according to an embodiment includes a stacking table, a first guide member, a second guide member, and a vibrator. The stacking table includes a stacking surface on which sheets are sequentially stacked. The first guide member is provided to stand on the stacking table. The first guide member restricts position of edges in a first width direction of the sheets stacked on the stacking table. The second guide member is provided to stand on the stacking table. The second guide member restricts position of edges in a second width direction of the sheets stacked on the stacking table. The second width direction intersects with the first width direction. The vibrator applies micro-vibration to at least one of the first guide member and the second guide member.
