(57) In a spinning machine (1), at least one operation out of a first operation performed by an air-jet spinning device (7) and a second operation performed by a yarn catching device (27) is executed during a period when the yarn catching device (27) catches a yarn end. The first operation is an operation of changing an air pressure in the air-jet spinning device (7) from a first air pressure to a different second air pressure at a time when the yarn is guided to outside, and the second operation is an operation of sucking, by the yarn catching device (27), the end of the yarn with a first suction pressure and thereafter continuing a sucked state of the yarn end with a different second suction pressure.
