Abstract (en)
Unintended sticking of a tray (T) due to a yarn (Y) that has fallen on a belt member (53) is prevented while the complexity of controlling a drive source (54) of the belt member (53) is avoided. A yarn supplying bobbin (Bs) conveying device (8) includes a flat belt (53) on which a tray (T) is placed, a plurality of belt feeding rollers (51, 52) around which a flat belt (53) is wound, and a motor (54) that rotationally drives at least one of the plurality of belt feeding rollers (51, 52). The flat belt (53) includes a plurality of protrusions (72) that support the tray (T) from below to apply to the tray (T) a frictional force for conveying the tray (T), and a base surface (73) disposed between the plurality of protrusions (72) in a width direction orthogonal to a conveying direction and a vertical direction, and below the protrusions (72) in the vertical direction.
