Abstract

A drafting device includes at least three roller pairs (15, 16, 17), each roller pair (15, 16, 17) including a bottom roller (15a, 16a, 17a) and a top roller (15b, 16b, 17b); and a fiber collecting device (80) having only one suction port (84) arranged facing a bottom roller (15a) of a third roller pair (15) from a downstream side in a drafting direction. When a distance between adjacent ones of the roller pairs (15, 16, 17) is a first distance, at least one of a shape and a position of the suction port (84) is in a first state. When the distance is a second distance, at least one of the shape and the position of the suction port (84) is in a second state. A downstream end portion (84b) of the suction port (84) in the drafting direction is positioned relatively on the downstream side in the drafting direction in the second state than in the first state.
