Abstract: The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method.Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

Abstract: A winding condition generating apparatus includes: an input unit; an output unit; and a condition calculation unit. A winding condition calculation unit includes a learning model created by machine learning using a combination of a winding parameter and a winding condition in producing a wound web that satisfies a target winding quality as training data, and calculates a winding condition of a new wound web using the learning model, from a winding parameter of a new wound web input through the input unit. The output unit outputs the winding condition. The winding parameter includes a web width, a web transport velocity, and a web winding length. The winding condition includes a tension of the web at the start of winding and a tension of the web at the end of winding.
