DEVICE FOR CENTERING WINDING TUBE

PROBLEM TO BE SOLVED: To surely fix the position of a winding tube among various lots of which the length, the diameter, and the material are different from each other, by selectively positioning a centering means on the preparation position related to the sort of the winding tube by means of a driving device of a holder for a plurality of centering means different from each other. SOLUTION: A readout station 41 reads out information from a tip provided on the supporting body 8 of a winding tube 102 for example. Information related to the length and the diameter of the winding tube is supplied to a control device 33 through a lead wire 41a. Next, the control device 33 controls a step motor at exchanging the winding tube, and a centering means 16d corresponding to the sort of the winding tube 102 to be wanted to clean, among six sorts of centering means 16a-16f different from each other, is rotated up to the centering position.
