(54) SPINNING MACHINE AND SPINNING METHOD


(57) A spinning unit 2 includes a draft device 6 adapted to draft a fiber bundle F and a pneumatic spinning device 7 arranged movable to a spinning position and a receded position and adapted to produce a yarn Y by applying twists to the drafted fiber bundle F by injecting whirling flow of air to a spinning chamber while being located at the spinning position. In the spinning unit 2, at least one of a first timing, which is a timing at which injection of the air is stopped when a drafting operation of the draft device 6 is stopped, and a second timing, which is a timing at which the pneumatic spinning device 7 starts being moved from the spinning position to the receded position when the drafting operation of the draft device 6 is stopped, is adjusted.
