To automate and save labor by enhancing general-purpose properties as well as winding performance and reliability.

An accumulator 20 is provided and disposed to the underneath of a rotation block 12 with spaces for opening/closing, allowing wire products in a spiral shape to drop down Y at the time of winding, and catching newly released wire product in a spiral shape for temporarily holding, and a cutting device 30 equipped with a pair of rotating cutters, is provided for a wire product route a6 released from the rotation block 12. A curvature forming device 40 with an adjustment mechanism 46, which curves and forms the wire product (a), is provided for the wire product route (a6) located between an releasing part underneath the rotation block 12 and a cutting part. This winder is equipped with a measurement unit 60 disposed underneath the accumulator 20, and with a dolly 50 with a rotation driving mechanism 57 which inclines (α) and set up a carrier 51 over a measurement instrument 60 so as to swing and rotate (Z) it.
