Tape winding method and device, and tape winding body

Abstract

In the tape winding method and the tape winding device according to the present invention, the first to the fourth rollers are provided, and the position and the like of the tape are restrained by the rollers. Therefore, the tape with the curvature amount of 6 mm or less per the tape length of 1 m can be wound up at a high speed and can be made favorable in the winding shape. Moreover, the position of the fourth roller is controlled so as to prevent contact of the tape to the shaft part surface of the fourth roller, and even if the curvature of the tape is large, the position of the tape in the width direction to the winding hub by the fourth roller can be reliably performed, as a result of which, winding of the tape which can provide a favorable winding shape is made possible.

 placing an axis of the winding hub to be horizontal;    restraining an entry direction of the tape into the winding hub by a first roller, which is provided at an upstream side in a tape traveling direction of the winding hub so that the axis of the winding hub and an axis of the first roller are substantially parallel with each other;    restraining a position of the tape in a width direction by a second roller which contacts a tape roll formed by the tape being wound around the winding hub, and is provided so that the axis of the winding hub and an axis of the second roller are substantially parallel with each other;    pressing the tape at an outermost periphery of the tape roll by a third roller provided so that the axis of the winding hub and an axis of the third roller are substantially parallel with each other;    restraining a position of the tape in the width direction by a fourth roller with a flange which restrains the position of the tape in the width direction while contacting the tape roll, in a downstream side in a tape traveling direction of the third roller at the outermost periphery of the tape roll, and is provided so that the axis of the winding hub and an axis of the fourth roller are substantially parallel with each other; and    winding the tape with a curvature amount of  6  mm or less per a tape length of 1 m around the winding hub.
