PROBLEM TO BE SOLVED: To provide an adhesive tape joint method, an adhesive tape joint device and an adhesive tape conveyance method capable of implementing jointing of the terminals of adhesive tapes certainly even when the adhesive tape has strong adhesive and various handling.SOLUTION: An extrusion member 33 projects a part of adhesion tape Tp of long adhesive tape T to a direction R approximately perpendicular to a delivery direction L. By a crimp roller 35 crimping the projecting adhesive tape Tp, a part of the adhesive tape T is formed as an exposed core. Since the exposed core projects a prescribed length to the direction R at a prescribed position Tf, the adhesive tape T can be manipulated by holding the exposed core easily and certainly. Further, since a length of the exposed core at a delivery direction L is very short, location accuracy of an area where handling is done to the long adhesive tape can be improved and large strength can be applied to a limited area of the adhesive tape T by doing handling holding the exposed core.SELECTED DRAWING: Figure 14
