Abstract: A flying reel change is accomplished by joining an exhausting web of a first reel that is to be replaced to a web of a fresh or replacement reel. The fresh reel is caused to run at the speed of the exhausting reel to be replaced prior to such joining. The exhausting web is joined to the fresh web once the diameter of the reel to be replaced has reached a set minimum. This minimum diameter may be fixed by the characteristics of a core for this exhausting reel.

Abstract: A reel changer is used to support rolls of material. A web of the material is unwound from one of the rolls while an additional roll of material is held for use in a roll changer when the first roll is exhausted. The rolls are each supported for rotation by two holding fixtures. Each of these holding fixtures has a supporting journal with gripping jaws. At least four collets are arranged in an axial direction of the supporting journals.
