The tab terminal 1 is pressed onto the adhesive tape 9a to be inserted and transferred to the adhesive tape 9a.

Next, a transparent tape 9b is drawn out from the transparent tape roll 27 on the upper surface thereof, a transparent tape 9b covering the adhesive tape 9a is overlaid, and the protective tape 9c drawn from the protective tape roll 28 is further aligned with the lower side thereof. (Not shown). At the same time as the taping drum 10 stops, the feeding of the adhesive tape 9a and the transparent tape 9b also stops. When starting or stopping, the adhesive tape 9a and the transparent tape 9b on which the tab terminals 1 are mounted are slackened. Therefore, in a state where the adhesive tape 9a and the transparent tape 9b are overlapped with each other, a U-shape is formed in the vertical direction by the tension roller 21. Bending, applying a predetermined load to the tension roller 21,
The slack of the adhesive tape 9a and the transparent tape 9b is absorbed by the vertical movement of the tension roller 21. In a take-up cassette roll (not shown), the peripheral speed differs depending on the winding diameter at the beginning and end of the take-up, and the take-up tape 9 is slackened or over-tensioned. The winding tape 9 rotates intermittently according to the tension applied to the winding tape 9 so as to adjust the tension of the winding tape 9 to be uniform. In addition, since the peripheral speed of the mounting tape 9 changes and the mounting tape 9 is excessively stretched or loosened, the winding cassette roll is wound around the winding cassette roll without loosening.
