To easily secure yarn having the desired rewinding length by cutting a tail bunch winding part of a yarn package, and sucking the tail bunch winding part by allowing an untying/loosening preventive member of rewinding yarn to abut to an end surface of a bobbin from the axial direction of the bobbin.
This manufacturing device of a yarn package is provided with a bunch cutter 7 as a means for cutting a tail bunch winding 1 being unnecessary yarn of a winding yarn body 3, and is provided with a removing means 21 for sucking/capturing the yarn end on the side connected to at least the winding yarn body 3 among two yarn ends of the tail bunch winding 1 generated by cutting. Such constitution can untie/loosen and pull out the desired length of the tail bunch winding 1 or a transfer tail 2 remaining in an end part of a bobbin 4 without being untied and loosened.
