Abstract

Method for cutting a web, during its winding in winders, with the aid of a cutting means extending over its entire width. A wire 9, stretched in the axial direction of the reel 8, is moved in order to bring it between the final and penultimate layer of the web 4 lying on the reel 8, and, after going beyond the point of contact between the reel 8 and a carrier roller 1 pressed on its periphery, it is moved away from the penultimate layer in order to cut the final layer of the web from it. <IMAGE>
