2. Description of the Related Art A conventional winder cutting device is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-123416.
A cutting device is installed in the winder main body, and when winding of a product tape of a predetermined length is completed and it becomes a nearly finished product reel, the product tape connected to the winder and the press is cut by the cutting device and the paper tape is also cut and cut. The end of the product tape was wound on the take-up reel to form a finished reel. Therefore, the finished product reel mounted on the reel support shaft disposed in the winder body is in a state in which the entire outer circumference is covered with the paper tape.

[0003]

When the outer circumference of the finished product reel is covered with paper tape, it is difficult to visually identify the product tape wound on the reel, and especially in a workplace where many kinds of product tapes are manufactured. In the above, misidentification of the product tape of the finished product reel becomes a problem in product management. In order to inspect the product tape wound on the finished product reel and display the product identification of the product tape, rewind while peeling off the paper tape conventionally wrapped around the outer circumference, pull out the end part of the product tape, and use scissors. The sample was cut by cutting.

The present invention is intended to rationalize the work by eliminating this sample cutting work.
