To provide a method for hooking yarns to a spinning and winding apparatus, a spinning and winding apparatus, and a suction gun which prevent an entanglement and a vibration of a plurality of yarns caused by a twist and a vibration from the suction gun, and facilitate a yarn hooking work.

There is provided a method for hooking yarn to a spinning and winding apparatus in which a plurality of yarns Y, whose yarn path is regulated by a first roller 21 or a first yarn path guide 22 of a spinning and winding apparatus, are hooked to a second roller or a second yarn path guide 23 on a downstream side of the first roller 21 or the first yarn path guide 22 by using a suction gun 61. The method includes: a first step for contacting a third roller 24 to the plurality of yarns Y between the suction gun 61 and the second roller or the second yarn path guide 23; a second step for hooking the plurality of yarns Y to the second roller or the second yarn path guide 23 in a state that the plurality of yarns Y are in contact with the third roller 24; and a third step for separating the third roller 24 from the plurality of yarns Y after hooking the plurality of yarns Y to the second roller or the second yarn path guide 23.
