PROBLEM TO BE SOLVED: To easily carry out replacement between an empty bobbin and a fully wound bobbin in a collective wire rough winder. SOLUTION: In this collective wire rough winder, a rotary shaft 1 is divided into a middle split shaft 1A and front and rear split shafts 1B and 1C. In each of the adjacent split shafts, a bearing 11 with a fitting recess part 12 formed in its end face is mounted in one end part, while a bearing 11 with a fitting projection part 13 formed in its end face is mounted in the other end part, and consequently, all the split shafts 1A, 1B, and 1C are fitted and connected mutually. In a device base 14, a bearing rack 15 is arranged for every fitting connection part. The bearing rack 15 is constructed of a fixing member 16 and a freely opening/closing movable member 17, and on each of joining faces between the fixing member 16 and the movable member 17 in closing the movable member 17, a semicircular groove 19 equivalent to a half of a shaft hole having a bearing outer ring fitting recess part 18 in the circumference direction is formed respectively. When the movable members 17 in the bearing racks 15 on the split shaft both sides are opened to release fitting in the fitting connection part, the middle split shaft 1A with a bobbin pair is removed from the bearing racks 15.
