To simultaneously and continuously stick the two strips of curing tapes at a prescribed interval onto both the sides of a joint and the like put there between.

In this tool, paired rotors 1 disposed at an interval are provided, and a masking adhesive tape 100 wound in a roll shape is detachably mounted on each rotor 1. A pressing means 2 is provided, which presses the back faces 103 of drawn-out portions 100' and 100' in the adhesive tapes 100 that are unwound and drawn out in a state that they are mounted on the paired rotors 1. After the drawn-out portions 100' and 100' of the paired adhesive tapes 100 mounted on the paired rotors 1 are stuck thereon, the moving operation of the adhesive tapes 100 in the unwinding direction thereby enables the two stripes of the adhesive tapes 100 to be continuously stuck at a prescribed interval while pressing the back faces 103 of the drawn out portions 100' by the pressing means 2.
