Abstract:
Power consumption when a yarn is conveyed by a yarn conveyance roller is effectively reduced. A guide roller 18 conveying yarns Y is covered with a roller cover 40. The roller cover 40 includes a first part 41 formed to be cylindrical and surround an outer circumferential surface 18a of a guide roller 18 and a circular second part 42 provided to face a leading end surface 18b of the guide roller 18 and connected to a leading end portion of the first part 41. The inner diameter Dc of the first part 41 is 1.6 times or more as long as and 1.9 times or less as long as the outer diameter Dr of the guide roller 18. In regard to the outer circumferential surface 18a of the guide roller 18 and the inner wall surface 41a of the first part 41, a difference between the distance (=Dc/2) from the axis J of the guide roller 18 and the radius (=Dr/2) of the guide roller 18 is constant and is equal to or longer than 40mm and equal to or shorter than 55mm.
