The possibility of allowing a yarn end on the package side where the formation of a package has been completed to be entangled on the empty bobbin side is reduced. A spun yarn take-up machine 1 includes bobbin holders 24A and 24B, a switching unit, a partition plate 65, and a controller 26. In a completed state in which a switching operation is completed, a package P is held by the bobbin holder 24A, and the partition plate 65 is at a partition position, a first virtual line segment VLS1 is defined. Two virtual tangents (a first virtual tangent VLT1 and a second virtual tangent VLT2) in contact with the outer circumferential edge of the bobbin holder 24B, which are parallel to the first virtual line segment VLS1, are defined. The partition plate 65 traverses across both of the two virtual tangents and is spaced apart from a yarn holding guide 44. The controller 26 positions the partition plate 65 at the partition position after the switching operation is completed, and starts to move the yarn holding guide 44 from a holding position toward a retracted position before the partition plate 65 reaches the partition position.
