At this time, since a part of the tape T in the circumferential direction is cut over the entire length of the work W, the frictional contact and rotation of the discs 41 and 42 as shown in FIG. By the movement, the tape T remaining on the work W is sequentially peeled off. The work W is transferred while being guided by the fifth transfer mechanism 6, and the tip of the work W is transferred to the sixth transfer mechanism 7.
Sensor 6d detects this, and the upper roller 7a of the sixth transfer mechanism 7 descends to clamp the work W. As a result, the work W is sent out with the tape T completely removed.

As described above, according to the tape peeling device of the present embodiment, a part of the tape T wound around the work W in the circumferential direction is subjected to the first and second cutting mechanisms 10 and 30. After cutting over the entire length of the workpiece W, the frictional contact with the workpiece W
