[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage reel suitable for continuously winding a long strip such as a thin plate material for press.

[0002]

2. Description of the Related Art Parts for electronic devices are produced by pressing a band-shaped thin metal plate and continuously producing it for easy handling in each process of manufacturing, carrying and assembling. In recent years, such a thin plate material for pressing has been lengthened, but since the diameter of the reel is limited to a certain size for the convenience of work, the strip after pressing is wound on one reel. It is difficult to take, and therefore, when the reel is full, the strip is cut at that position and wound on a new reel.

However, if the strip after processing can be wound up in the same length without being cut in the middle, it is not necessary to stop the press work and the winding work many times, and the labor of work is greatly reduced. Not only does the processing accuracy increase, but
The mold is also protected and its durability is increased.
