This invention relates to a cutting and rewinding method and a winding device, particularly suitable for cutting a slightly adhesive film without stopping its transport and winding it around a new empty core. Regarding equipment.

けるという自動切断巻替えを行うものである。(Prior Art) Conventionally, multi-axis turret type winding devices have been widely used for winding adhesive films, synthetic resin films, and the like. This multi-spindle turret type winder is capable of rewinding a new core S as the film is wound onto the core without stopping the transport of the film being wound. When the winding core is close to the 1st winding position during winding, the winding position will change from this winding position. ? Automatic cutting in which R is rotated to move the core, then the empty core is fed to the winding position, the film is cut while being wound onto the /I'li core, and the starting end of the cut film is wound around the empty core. This is for rewinding.

スカット法かのいずれかが採用されている。The cutting method for cutting and rewinding the film in the above-mentioned multi-axis turret winding device is the saw blade method, which cuts instantly with a straight saw blade, or the saw blade method, in which the cutting blade is moved perpendicular to the film transport direction. One of the traverse cutting methods is used.

。(Problems to be Solved by the Present Invention) However, in the former cutting and rewinding method using the saw blade method among the above-mentioned conventional techniques, when used for cutting and rewinding an adhesive film, etc., the adhesive surface of the film is empty. It is suitable because it adheres to the winding core, but when used for cutting and rewinding slightly adhesive films or non-adhesive synthetic resin films, the starting end of the cut film is difficult to wrap around the empty core. Even if winding is performed by blowing air onto the starting end, in the case of a thin, flexible film, there is a problem in that wrinkles may occur due to bending at the cut portion or air being drawn in when the film is wound.

端部付近がロスとなってしまうという問題があった。In addition, in the latter method of cutting and rewinding using the traverse cut method, since the cut portion of the film is cut across the film while it is running, it is naturally cut diagonally across the width direction of the film. The part of the right triangle with the cutting line as the hypotenuse becomes the loss part of the film, and in the case of a slightly adhesive film, if the film is run on an air-wound core just before cutting and rewinding, that part of the slightly adhesive film will be lost. There has been a problem in that the adhesive force decreases due to contact with the core, resulting in loss near the end of the roll wound around the core.
